The Survival of Andalusi Artistic Formulas in the Time of Hernan

In the transition from the Middle Ages to the Modern Era, Hernan Ruiz I worked as master builder of the Cathedral of Cordoba. His works exemplify the adoption of an artistic language resulting from the symbiosis of Gothic, Renaissance and Islamic formulas. In this paper, we demonstrate the imprint of the Andalusi aesthetic in this master’s work. Through an analysis of his building works and the evolution of his style, we show that Hernan Ruiz I’s legacy is more important than what historiography has previously suggested, which has only addressed the transition in his architectural style from Gothic to Renaissance and has overlooked the impact of Andalusi formulas in his work. Hernan Ruiz I bore witness to an important change in the mentality and aesthetic tastes of his time, and although his son, Hernan Ruiz II, gained greater recognition for his work, his father was able to adapt a church model imbued with the medieval spirit to the demands of the new patrons, namely the nobility and high clergy. These clients imposed their tastes, which were anchored in the past, but were open to new Renaissance influences due to their humanistic training and, at the same time, attracted by the exoticism and prestige of Andalusi art.


Introduction
At the turn of the fifteenth to the sixteenth century, marked by the transition from the Middle Ages to the Modern Era, the master architect Hernan Ruiz I, also known as the Elder (1479?-1547), was active in the city of Cordoba, Spain.This article aims to contextualize his building works with a view to understanding the important role he played in the passage from medieval to modern architecture, and how the Andalusian influence (Islamic tradition in the ancient al-Andalus) endured in his work through the use of certain elements that merged with other elements of Christian origin.It supposed the constitution of a great example of architectural hybridization that is still surprising today (Burke 2010;Dodds et al. 2008).The powerful image of the Mosque of Cordoba defined the following constructions inside it, such as, for instance, the Royal Chapel (Ruiz Souza 2006), which resulted from the great exchange of cultures.
His homonymous son, Hernan Ruiz II the Younger, is much more well known, mainly due to his treatise on architecture, his successful intervention in the Giralda bell tower of the Seville Cathedral and other outstanding works.Most of these works are documented, as has also occurred with his son, Hernan Ruiz III.
Hernan Ruiz I may have been less studied than his descendants because his work is not as widely documented.We do not intend to carry out an in-depth analysis here, but rather to undertake a task we owe to this master, and which historiography has tended to overlook, attracted more by the brilliance of his descendants.In their classic study of Hernan Ruiz II the Younger (Banda y Vargas 1974), A. de la Banda y Vargas provided some biographical data on Hernan Ruiz I and briefly mentioned some historical and artistic aspects of this master's works.For his part, M. Nieto Cumplido provides additional information on his origins, carries out a historical and artistic study of San Juan Bautista

Hernan Ruiz I's Intervention in the Mosque-Cathedral of Cordoba
Although the work of Hernan Ruiz I has been studied using a variety of approaches, whether formal, historical or architectural, our intention is to show, above all, the apparent ease with which the master architect combined the solutions handed down from centuries of Islamic building experience with the advances of late Gothic architecture (especially the stellar vaults) and the Renaissance influences imported from Italy.
It is interesting to observe how in the new chancel, built inside the original Aljama Mosque after 1523-"an intervention that Christianizes completely the building" (Urquízar Herrera 2003)-following a well-known controversy between the cathedral chapter and Bishop Alonso Manrique, the driving force behind the project (Nieto Cumplido 1998), Hernan Ruiz I dedicated his efforts to constructing Gothic vaults in order to create a luxurious ensemble along the perimeter of the Latin cross floor plan that marked the new intervention (the chancel, transept and choir) (Figure 1b).In contrast, however, he achieved a perfect symbiosis in the walls between the pre-existing Umayyad Caliphate arches-which he took advantage of to design the tracery-by combining the Islamic arrangement of small blind arches of the sebka type with the typologically Christian shape of the pointed or trefoil arches (Figure 2a).In addition, the elevation of the east and west sides, with their triple arcades sheltered by a semicircular relieving arch, is reminiscent of the basic structure of the Ambassadors hall in the Alcazar of Seville.Moreover, on the north and south sides of the transept, he not only overlaps the arches, but also emphasizes the superior arches by using a drip cup with Christian plant motifs in the spandrels (Figures 2b and 3).He finalized the caliphal inspired structure with a frieze of blind arches, a solution that had already been used in the San Sebastian gate of the mosque, and that major achievement was the façade of the mihrab.Consequently, the sources of inspiration for the master seem obvious, to which he also greatly contributed.In contrast, however, he achieved a perfect symbiosis in the walls between the pre-existing Umayyad Caliphate arches-which he took advantage of to design the tracery-by combining the Islamic arrangement of small blind arches of the sebka type with the typologically Christian shape of the pointed or trefoil arches (Figure 2a).In addition, the elevation of the east and west sides, with their triple arcades sheltered by a semicircular relieving arch, is reminiscent of the basic structure of the Ambassadors hall in the Alcazar of Seville.In contrast, however, he achieved a perfect symbiosis in the walls between the pre-existing Umayyad Caliphate arches-which he took advantage of to design the tracery-by combining the Islamic arrangement of small blind arches of the sebka type with the typologically Christian shape of the pointed or trefoil arches (Figure 2a).In addition, the elevation of the east and west sides, with their triple arcades sheltered by a semicircular relieving arch, is reminiscent of the basic structure of the Ambassadors hall in the Alcazar of Seville.Moreover, on the north and south sides of the transept, he not only overlaps the arches, but also emphasizes the superior arches by using a drip cup with Christian plant motifs in the spandrels (Figures 2b and 3).He finalized the caliphal inspired structure with a frieze of blind arches, a solution that had already been used in the San Sebastian gate of the mosque, and that major achievement was the façade of the mihrab.Consequently, the sources of inspiration for the master seem obvious, to which he also greatly contributed.Moreover, on the north and south sides of the transept, he not only overlaps the arches, but also emphasizes the superior arches by using a drip cup with Christian plant motifs in the spandrels (Figures 2b and 3).He finalized the caliphal inspired structure with a frieze of blind arches, a solution that had already been used in the San Sebastian gate of the mosque, and that major achievement was the façade of the mihrab.Consequently, the sources of inspiration for the master seem obvious, to which he also greatly contributed.The way in which Hernan Ruiz I closes the chancel towards the Islamic prayer room with an ornate net of subtle arches that seems to imitate the forest of columns is similarly interesting (Figure 4).In contrast, the tenacity with which Hernan Ruiz I constructed the Gothic vaults surrounding the central cross is astonishing.Upon closer examination, however, it becomes apparent that the creation of a sequence of stellar vaults built upon the Caliphate columns and arches was the most practical and obvious way of ensuring that the new Christian construction would stand out.It was a pragmatic solution, since it would surely have been a daunting challenge to replace the old supporting structures with new ones.
Thus, his intervention was aimed at inexorably imprinting the Christian seal on the enclosure, which, on the other hand, marked a clear difference between the new liturgical space and the old Islamic one in a more visual way.In doing so, the processional walkway was perfectly distinguishable for the canons and marked the way to the cross of redemption that stood symbolically in the center of the Muslim prayer hall (Moreno Cuadro 2007) (Figure 5).The way in which Hernan Ruiz I closes the chancel towards the Islamic prayer room with an ornate net of subtle arches that seems to imitate the forest of columns is similarly interesting (Figure 4).The way in which Hernan Ruiz I closes the chancel towards the Islamic prayer room with an ornate net of subtle arches that seems to imitate the forest of columns is similarly interesting (Figure 4).In contrast, the tenacity with which Hernan Ruiz I constructed the Gothic vaults surrounding the central cross is astonishing.Upon closer examination, however, it becomes apparent that the creation of a sequence of stellar vaults built upon the Caliphate columns and arches was the most practical and obvious way of ensuring that the new Christian construction would stand out.It was a pragmatic solution, since it would surely have been a daunting challenge to replace the old supporting structures with new ones.

Despite his harsh words, Gautier described the cathedral as being "one of the most marvellous buildings in the world" (Pardo Rodríguez 1989).In addition, although he reproached the alterations made to the mosque, his recognition of the Christian construction suggests that Hernan Ruiz had put enormous effort into integrating the different styles.This, as we pointed out, can be seen in the way in which the Caliphate arches in the lower parts were used to provide a Christian ascent that culminated in the great vaults of Gothic design and Renaissance ornamentation built by his successors (Figure 6).If the impression of a nineteenth-century traveler such as Gautier was that "Cordova has more of an African look than any other Andalusian city", to such a point that he claimed "if the Moors were to return, they would not have to alter much before settling down" (Sumichrast 1912), then it would not be surprising that this perception was much stronger in Hernan Ruiz's time due to the countless buildings from previous eras that must have remained standing.Although Gautier was very critical of the chancel, transept and choir, he acknowledged the fine work of Hernan Ruiz: This parasitic church, a monstrous stone mushroom, an architectural wart which has grown on the back of the Arab building, was constructed from the designs of Hernan Ruiz, and is not without merit in itself; anywhere else it would be admired [...].

The gallery of arches of the Orange Tree Courtyard in the Mosque-Cathedral is the other intervention which reveals this syncretism between Islamic and Christian elements.Although the courtyard's authorship has not been certified, the evidence seems to indicate that it may have been the work of the master's hand.The round stilted arches resting on columns with Arab capitals framed by a drip-cap offer an evocative image that speaks of this perfect ensemble of elements of diverse cultural origin, which blend together elegantly (Figure 7).It is a widely accepted formula employed in various types of works (San Sebastian and Anton Cabrera hospitals, Santa Clara Church, the Santa Marta and Capuchin cloisters, the portico of the Casa de las Campanas, etc.).What is striking about the solution adopted by the master in the courtyard of the Mosque-Cathedral is the way he incorporated Christian elements in the drip-cap, which he emphasized with a series of moldings, among which a thick reed one stands out.This formula was also used in the San Miguel door located on the west wall of the enlargement made by Abd al-Rahman II, in which the coat of arms of Bishop Juan Daza (1504-1510) is displayed.We believe that it is an example that perfectly illustrates how a former door of the Mosque was Christianized by means of a drip-cap (Jordano Barbudo); an element that would be widely employed in this type of intervention.Indeed, in the architecture of the Pedroches, an area in the north of the province of Cordoba, these drip-caps would continue to be a recurring feature almost until the present day.It is possible that the formula was devised by Hernan Ruiz I for the Orange Tree Courtyard and, given its acceptance, was widely used.

Hernan Ruiz I and the Consolidation of the Parish Model
The parish church model that was imposed at the end of the thirteenth century in Cordoba and served to erect the first Christian temples in the conquered city had a layout consisting basically of three naves and a triple apse.These churches incorporated few Islamic elements, as it seemed that the Christians wanted to visually symbolize the supremacy of the new religion and therefore limited the presence of Andalusi features.Although it is not our intention to address this question here, as it has already been studied on other occasions (Jordano Barbudo 2002), it is revealing that Hernan Ruiz I, master builder of the Cathedral of Cordoba and visitator of the bishopric-a figure that was responsible for overseeing the existing buildings in the province belonging to the Diocese of Cordoba-maintained the model that had been used systematically since the thirteenth century, although he adapted it to fit in with the new aesthetic trends.The fact is that the churches built in the time of Hernan Ruiz I maintain the same floor plan mentioned above, but with some changes.The one that most singularly affects the topic of this study is the evolution of the wooden ceilings parallel to the construction of the Gothic vaults covering the apse.Indeed, while the latter displayed an increasingly elaborate ribbed design with a greater number of additional decorative elements and were more complex than the simple ribbed vaults of the thirteenth century, the carved and pictorial

With regard to the carved wooden ceilings, it is important to mention their geometrical decorative elements, such as carved hexagonal (alfardones) and lobed (chillas) pieces, which are decorated with paintings.However, the tie-beams are also made more complex through the use of stars that often stand out for their beauty and size.The muqarnas ornaments resembling stalactites or honeycomb gain in sumptuousness and are usually gilded.The girder and other supporting parts of the frame are now richly painted with plant motifs interwoven with bright colors.In addition, there are heraldic motifs and even calligraphic inscriptions, sometimes in Latin, but more often in Kufic Arabic script.
Thus, the model that had been used since the conquest to build the first churches belonging to the religious orders of the Dominicans (the Real Convento de San Pablo, 1241) and Franciscans (San Pedro el Real, ca.1241) was consolidated.Hernan Ruiz was receptive of this model and brought it to its height in examples such as the parish church of San Juan Bautista in Hinojosa del Duque, which was completed by his son Hernan Ruiz II and Juan de Ochoa (Figure 8).
This example shows the evolution with respect to the original model because, among other reasons, the double arcade of the Cistercian church which had been one of the characteristic elements of the Cordoban parish church model, was simplified.Although clearly based on this model, it was stylized in line with this new interpretation.The almost generalized pointing of the upper arches (which are not quite round) and the disappearance of the robust cornice on which the framing rested in the city's churches contributed to this.The ceiling, on the other hand, is more elaborate.As we mentioned, the boards are more richly carved and are decorated with a great variety of plant, geometric, epigraphic and sometimes heraldic motifs.decorated with paintings.However, the tie-beams are also made more complex through the use of stars that often stand out for their beauty and size.The muqarnas ornaments resembling stalactites or honeycomb gain in sumptuousness and are usually gilded.The girder and other supporting parts of the frame are now richly painted with plant motifs interwoven with bright colors.In addition, there are heraldic motifs and even calligraphic inscriptions, sometimes in Latin, but more often in Kufic Arabic script.

It is not difficult to see that this model was quite widespread and reached new heights, as evidenced in the construction of Nuestra Señora de la Asunción of Dos Torres, a town near Hinojosa, although the church dates back to a later period.The coat of arms of Bishop Martín de Córdoba y Mendoza was displayed in the chancel, so it is dated between 1578 and 1581 and can be attributed to Hernan Ruiz III (Nieto Cumplido).
The old town of Pedroche, where the church dedicated to the Transfiguration of the Savior was erected, is not far from here.The church has not been attributed to any master, but it is in the same typological line that we have described above, and it would not be surprising if it were designed by Gonzalo Rodríguez and perhaps concluded by his son, since the coat of arms of the Catholic Monarchs after the incorporation of Aragon (1479) can be found in the choir.This is another example of the consolidation of the parish model, although in this case the Islamic imprint is perceived in a more visible way.The octagonal piers are of a characteristic Mudejar type that was common precisely under the Catholic Monarchs.At least that is what we have identified in the case of Cordoba.Moreover, the pointed arches are framed by drip-caps, which is uncommon in churches of this type, and there are oculi instead of windows above the arches.However, perhaps the most remarkable aspect of these churches is the presence of wooden carpentry, which, apart from the collar-beams, also included a wooden choir decorated with paintings and supported by curvilinear corbels of Andalusian inspiration.The parapet is decorated with eight-pointed star latticework, but the most extraordinary feature is the combination of motifs of Islamic origin-including inscriptions in Neski-with purely Gothic motifs, such as thistle leaves, which also decorate the ceiling.The boards of the ceiling have carved alfardones and chillas embellished with leaf motifs typical of the Islamic and other Gothic styles; a style that is also represented by the flamboyant tracery with Almohad motifs, such as the intertwined octagons.The connection that shows this rich decoration with the singular ceilings of the convent of Santa Clara de la Columna in Belalcazar, another of the nearby towns, indicates that crews of artists must have moved from one place to another in search of patrons and building works.It therefore seems evident that the same workers would have been hired by the Counts of Belalcazar to build the aforementioned convent.In fact, the flat ceiling with latticework (taujel) in the baptistery of the parish church of Pedroche is very similar to the ceilings found in Santa Clara since, like the convent, it is decorated with a rope motif alluding to the Franciscan Order (Jordano Barbudo 2002).
Unlike the architecture of Pedroches, with its characteristic grey granite, further south in the province in the town of Montoro it is the reddish-colored stone which lends a distinctive mark to the architecture.The parish church of San Bartolomé gives us the opportunity to see first-hand the image through the visitator general's eyes.Let us not forget that Hernan Ruiz himself was a visitator general, and although he may not have intervened directly in this work, he at least left his signature on it.The chancel, with its three vaulted chapels with Gothic tiercerons, originally displayed the coat of arms of the bishop of Cordoba, Bro Bernardo de Fresneda (1572-1577).However, given the late date of his episcopate (much later than the time of Hernan Ruiz I), his coat of arms may have alluded to some reform of the church, since the vaults would have been very archaic at that time.What is interesting here is the visitator's description of the church contained in his report: He also visited the material body of said church, which had three naves built of carved millstone from barbers' shops with good bases without carvings or moldings.The chancel was made of the same carved stone.The stone-vaulted ceiling with moldings and ribbons with their pine cones, gold mouldings and the coat of arms of the good Bishop Bernardo de Fresneda, and on the apse ends of the side-aisles there were two other chapels with stone vaults with moldings and ribbons without mouldings.The roof of the main nave was made of carved pine wood with a latticed pattern decorated with gold pine cones, and the ceilings of the side-naves were of wooden beams and brick [...] (Nieto Cumplido).
As this text indicates, another beam and brick system was widely used, which in the case of San Bartolome was reserved for the aisles.It is important to recall that in the cloister of San Sebastian Hospital, located just across from the Mosque-Cathedral of Cordoba, this type of enclosure was also used to cover the galleries of the courtyard; a work that has been attributed to Hernan Ruiz I. Vestiges of this system can also be seen in the Anton Cabrera Hospital and the Capuchin and Santa Cruz cloisters, among others.Clearly, it was a simpler structure, but also with striking results, since the surface of the brick that was left exposed was usually painted with plant, geometric and even epigraphic motifs of either Islamic or Christian influence (flamboyant stencils, for example).
Although not documented, it is assumed that Hernan Ruiz I oversaw the building works of Nuestra Señora de Soterraño, the parish church of the town of Aguilar de la Frontera, which replaced the previous church, which was too small to accommodate the population (Luque et al. 1981) (Figure 9).This work marked the beginning of the master's turn towards the new architectural styles coming from Italy.However, was this of his own making, or was the mind of a humanist behind him?It has been said that Catalina Fernandez de Cordoba, II Marchioness of Priego and wife of Lorenzo Suarez de Figueroa, Count of Feria (Nieto Cumplido 1984), was responsible for commissioning the works.In his extensive study of the counts of Feria, Rubio Masa states that the library of Lorenzo III Suarez de Figueroa (1505-1528) housed 284 volumes, including many by Italian humanists (Rubio Masa 2001).It should be noted that his palace in Montilla was connected by a passageway to the convent of Santa Clara; a work in which, as we have said, the master also intervened.At that time, Montilla was the capital of the count's seigneury and included, among others, the villa of Aguilar.
Up to this time, there had been a process of integration that merged elements of Islamic inspiration with the Christian ones of Gothic architecture, but the time had come to usher in the Renaissance, and it is these new airs that can be perceived when entering Soterraño Church.Although the model is the same as that of the first churches built after the Christian conquest, these constructions are more diaphanous, which is achieved by means of slender piers; a perception that the visitator general of the bishopric of Cordoba expressed in his report when he described the church as being "of good foundation and talent, grand and well finished" (Nieto Cumplido).The church of San Mateo in the town of Lucena was built in the same style, and although later than Soterraño, it was also commissioned by another of the most powerful lineages of the Kingdom of Cordoba, which, like the previous ones, belonged to the great House of Cordoba: the lords of Chillon, Espejo and Lucena, who would be granted the distinction of Marquises of Comares.
In both cases, the staggered triple-apse arrangement and diverse floor plans (hemicycle, polygonal, straight or alternating) characteristic of the first period were substituted for an apse end consisting of three flat chapels laid out in a line, as in the case of Soterraño, or a somewhat deeper central chapel, such as that of Lucena.In both examples, it is clear that the aim is to make the space as uniform as possible to achieve a visual perception of transparency.
In Aguilar, the ribbed vault of the chancel is divided into eight webs, and the keystone bears the coat of arms of the Fernandez de Cordoba family.In contrast to this archaic roofing, it is important to highlight the segmental triumphal arch, which was a new development.In the same way, the molding of the vault, the piers on which it rests, and the smaller capitals mark this trend towards simplification to achieve a sensation of openness.A similar assessment could be made of the naves, whose piers suggest a change in plans.However, without a doubt, what is most worthy of mention in the assimilation of Andalusi formulas is the collar-beam wooden ceiling of the main nave, where the corbels supporting the tie-beams display the classicist acanthus leaves, thus indicating the contribution of the new Renaissance styles.Far from lessening the splendor of these wooden ceilings, they are better resolved, technically, through the use of more complex solutions (Figure 10).The tie-beams, for example, are decorated with double latticework patterns that create stars of considerable size, such as those to be found in the Animas Chapel of the Asuncion Church in Santaella.
Hospital, located just across from the Mosque-Cathedral of Cordoba, this type of enclosure was also used to cover the galleries of the courtyard; a work that has been attributed to Hernan Ruiz I. Vestiges of this system can also be seen in the Anton Cabrera Hospital and the Capuchin and Santa Cruz cloisters, among others.Clearly, it was a simpler structure, but also with striking results, since the surface of the brick that was left exposed was usually painted with plant, geometric and even epigraphic motifs of either Islamic or Christian influence (flamboyant stencils, for example).

In both cases, the staggered triple-apse arrangement and diverse floor plans (hemicycle, polygonal, straight or alternating) characteristic of the first period were substituted for an apse end consisting of three flat chapels laid out in a line, as in the case of Soterraño, or a somewhat deeper central chapel, such as that of Lucena.In both examples, it is clear that the aim is to make the space as uniform as possible to achieve a visual perception of transparency.
In Aguilar, the ribbed vault of the chancel is divided into eight webs, and the keystone bears the coat of arms of the Fernandez de Cordoba family.In contrast to this archaic roofing, it is important to highlight the segmental triumphal arch, which was a new development.In the same way, the molding of the vault, the piers on which it rests, and the smaller capitals mark this trend towards simplification to achieve a sensation of openness.A similar assessment could be made of the naves, whose piers suggest a change in plans.However, without a doubt, what is most worthy of mention in the assimilation of Andalusi formulas is the collar-beam wooden ceiling of the main nave, where the corbels supporting the tie-beams display the classicist acanthus leaves, thus indicating the contribution of the new Renaissance styles.Far from lessening the splendor of these wooden ceilings, they are better resolved, technically, through the use of more complex solutions (Figure 10).The tie-beams, for example, are decorated with double latticework patterns that create stars of considerable size, such as those to be found in the Animas Chapel of the Asuncion Church in Santaella.The San Mateo Church of Lucena may be considered the final link in the evolution of the parish model during Hernan Ruiz I's time (Figure 11).That this church was built at a later date (the end of the fifteenth or beginning of the sixteenth century) could be due to the fact that elements recovered from the Lucena's aljama or Great Mosque were used in its construction, as had occurred in Cabra, for example, and perhaps also due to its proximity to the border with the Nasrid Kingdom of The San Mateo Church of Lucena may be considered the final link in the evolution of the parish model during Hernan Ruiz I's time (Figure 11).That this church was built at a later date (the end of the fifteenth or beginning of the sixteenth century) could be due to the fact that elements recovered from the Lucena's aljama or Great Mosque were used in its construction, as had occurred in Cabra, for example, and perhaps also due to its proximity to the border with the Nasrid Kingdom of Granada.The Christian victory at the battle of Lucena in 1483, with Boabdil imprisoned, must have been another important reason.The new work, which was undertaken following the demolition of the previous construction in 1498, was made possible thanks to the patronage of Diego Fernandez de Cordoba, I Marquis of Comares, and whose son Luis continued later.The model of the first parish churches of Cordoba underwent a substantial change, as can be seen in the notable increase in their diaphanous space as described above.This was achieved through the use of simple, slender piers, now with small, unadorned capitals, but also by elevating the arches and building naves of equal height, which lent these churches a very similar appearance to that of the hall churches inspired in the German hallenkirche (Figure 12).We must also add another factor that differs from the other examples analyzed here: the use of a drip-cap on the wall-ribs; a feature that may be attributable to the closer proximity to Islamic territory.Following the pattern of previous cases, the naves were covered with wooden ceilings, the central one being of the collar-beam type, and the apse end was designed with three straight chapels, the central one of which projects out a bit from the rest.The vaults are all stellar, although they became increasingly complex in their design and number of ribs.This may be due to the fact that in the last decade of the sixteenth century the chapels were sinking, which forced the Count of Pradas to authorize a payment of 74,592 maravedis in order to "build the three chapels of the church, the chancel and the side chapels" (Nieto Cumplido, forthcoming a).
The lateral portals of the Virgin and San Miguel have been attributed to Hernan Ruiz I.They were also built using the same scheme and with a similar drip-cap.It is a pity that the inner doorway that leads to the sacristy has been torn down.It seems that the round arch may also have had a similar drip-cap, as the first springers would seem to indicate.If this were the case, the entire ensemble would have perfectly combined these influences, as the decorative program could not be more Christian with the coat of arms of the Marquises of Comares bearing the fesses of the Cordoba lineage-the chained head of Boabdil and the flags that were won from him flanked by two lions-while the molding that forms the drip-cap is decorated with thistle and animal motifs, thus displaying an image of power and propaganda.The model of the first parish churches of Cordoba underwent a substantial change, as can be seen in the notable increase in their diaphanous space as described above.This was achieved through the use of simple, slender piers, now with small, unadorned capitals, but also by elevating the arches and building naves of equal height, which lent these churches a very similar appearance to that of the hall churches inspired in the German hallenkirche (Figure 12).We must also add another factor that differs from the other examples analyzed here: the use of a drip-cap on the wall-ribs; a feature that may be attributable to the closer proximity to Islamic territory.Following the pattern of previous cases, the naves were covered with wooden ceilings, the central one being of the collar-beam type, and the apse end was designed with three straight chapels, the central one of which projects out a bit from the rest.The vaults are all stellar, although they became increasingly complex in their design and number of ribs.This may be due to the fact that in the last decade of the sixteenth century the chapels were sinking, which forced the Count of Pradas to authorize a payment of 74,592 maravedis in order to "build the three chapels of the church, the chancel and the side chapels" (Nieto Cumplido).

The Box Floor Plan of Female Conventual Churches
The other model that was characteristic of Hernan Ruiz I's work was the box floor plan typical of convents; that is, a rectangular layout which was adapted perfectly to the needs of the nuns and their promoters since it allowed the nuns to attend liturgy, either from the choir and sotocoro, or through the rood screen of the main altar, while it also provided a place for the founders to be buried, usually in the chancel.This model was first used in the Monastery of San Juan de los Reyes of Toledo, which was commissioned by the Catholic Monarchs.Perhaps the earliest example in Cordoba is that of Santa Marta, a Hieronymus monastery where Hernan Ruiz I's sister took the name of Sister Maria de San Miguel upon professing her vows, and whose church appears to have been founded circa 1479 by their father, Gonzalo Rodriguez (Banda y Vargas 1974).The formula is very simple: the chancel is covered with Gothic stellar vaults and the nave with ridge-ribbed vaults, although the choir This portal of the sacristy is a perfect example of what we are attempting to transmit, here, because, in our opinion, it reveals the aesthetic trends of a society transitioning from Medieval to Modern times in the passage from the Gothic to the Renaissance, with a still-notable Islamic presence of the former Al-Andalus, which was now Christian.Logically, the mentality of the master, in this case Hernan Ruiz I, was also changing, and in attending to the demands of a humanistic-minded clientele, he laid the foundations for the subsequent arrival of Renaissance styles.For this reason, even though he may not have achieved the fame of his son Hernan Ruiz II, he was able to adapt to the changing tastes of his clientele.After the initial phase of the Reconquest, when the first parish churches had been built thanks to the administrative organization of the dioceses (only the conventual temples of San Pablo and San Pedro el Real were commissioned by the king), Hernan Ruiz I was prepared for what would come later: the almost complete control over building undertakings by the nobility and even the ecclesiastical dignitaries.This enabled them to convey the propaganda of their lineage using heraldry to gain notoriety, while patronage was a form of atonement and a way to ensure a privileged place of burial in the churches they themselves had commissioned to be built.

In 1480, the chancel was not yet finished, but seven years later the first Counts of Cabra were buried there.However, it is likely that the work was not completed until the first decade of the fifteenth century.The portal is dated 1511 and is the work of Hernan Ruiz I (Banda y Vargas 1974).It should be noted that the late Gothic-style portals in the city-the first of which was this example of the Hieronymus monastery-underwent a clear evolution (Santa Marta, San Andres, San Jeronimo and San Sebastian churches), especially this one of Santa Marta (Figure 13a) and that of San Sebastian Hospital, where the master erected an ogee arch decorated with foliage, clusters flanked by savages-one playing a horn and the other holding a rope (Figure 13b)-and tracery spandrels embellished with small arches and a type of drip-cap reminiscent of a brief roof (tejaroz).The characteristic feature is that the surface of this drip-cap, which is constructed from two piers that flank the portal, is adorned with tracery in the form of intertwined arches resembling the Almohad sebka.These elements led A. de la Banda to describe them as "faint but certain Mudejar influences" (Banda y Vargas 1974).The formula is repeated again in San Sebastian Church, although with later solutions and an obvious taste for what is traditionally known as the Plateresque style.This system of Christianized drip-cap and elaborate spandrels with a network of arches is the same one that Hernan Ruiz I would use in the Cathedral transept some years later.Thus, it could be inferred that Santa Marta and San Sebastian were his 'testing grounds' with regard to this particular feature, although the master may have built other works with this same formula that have not survived.

However, the Santa Clara Convent of Montilla is paradigmatic in this sense.Not only is there a tribune above the chancel where the Marquises Priego could attend the services, but also an elevated passage over the street connected to their palace which provided direct access to the church (Casado Alcaide and Jordano Barbudo 2010).
It is very revealing that the simple nave and chancel model in which the spaces are not architecturally distinct (Gimena Córdoba 2015), the first example of which is probably Santa Marta, is more similar to Christian formulas due to the ribbed-vault ceilings.However, from that time on, there was a tendency to use the Islamic-style wooden ceilings, which were of a quality and opulence comparable to that of the Christian vaults.Moreover, the individual covering of the chancel, which was also separated by means of a triumphal arch, lent this part of the church greater autonomy.This scheme was a reinterpretation of the Islamic qubba system; that is, a construction with a square floor plan that symbolized the earthly versus the celestial, represented in this case by a domed wooden structure sprinkled with stars (e.g., Guadalupe Church in Baena, Jesus Crucificado Hospital in Cordoba).

Epilogue. The Death of Hernan Ruiz I and His Burial in the Mosque-Cathedral of Cordoba
In his work La catedral de Córdoba, M. Nieto Cumplido states that Hernan Ruiz must have died in early September 1547, because on the 6th of that same month his widow engaged in litigation over the will.According to one witness, she attended the death of the master builder and his burial in the city's main church.Nieto posits that he might have been buried with his son Juan Ordóñez, the prebendary of the cathedral, under one of the two arches on the south side of the transept.Indeed, it is here where a tombstone bearing his shield can be found.The chronicle of M. Medina González, published in the Diario Córdoba newspaper of 9 March 1943, in which he refers to the discovery by Enrique Romero de Torres of Hernan Ruiz I's remains in this burial place, confirms that this is the where master lies (Figure 16a).Romero de Torres, driven by his innate curiosity, located the will of Juan Ordoñez dated 6 November 1604.As prebendary of the Cathedral Church of Cordoba, he said: When God our Lord is served by my paying this natural debt and I am deceased, my will is that my body be buried in the Cathedral Church of Cordoba, in the tomb I have in said church, where Hernan Ruiz, my father, master builder of said holy church, is buried, which is under an arch of one of the side chapels of the new transept where there is a marker that tells when the new work was begun.
After receiving the pertinent authorization Enrique Romero de Torres had requested from the Cathedral Chapter, and under the direction of the architect Felix Hernandez, the tomb was opened and a burial vault was found which had been carved into the stone of the foundation of an arch.The burial vault contained the remains of two bodies facing east mixed with earth, wood debris, leather, fabric and lace.In the center, on the body of the son, appeared the skull of Hernan Ruiz I surrounded by bones.
The remains were placed in a new brick and cement burial vault, along with a copper plate indicating the date they were found.Afterwards, the ledger stone of the prebendary was put back in its original place, as we can see it today (Figure 16b).In the arch beneath which this ledger stone is located, there is an inscription dedicated to the work of his father Hernan Ruiz I: "He began this new work of this Holy Cathedral Church on 7 September 1523, the bishop being Alfonso Manrique" (Figure 2b).The desire of the prebendary, son of Hernan Ruiz I, to be laid to rest with his father was thus fulfilled.Today, therefore, it is possible to corroborate Nieto Cumplido's hypothesis about the burial place of the master builder.The investigation carried out by Enrique Romero de Torres, the interest of the cathedral chapter in granting his request to open the tomb and the intervention by the architect of the Mosque-Cathedral, Felix Hernandez, led us to the exact place.
The year 2047 will mark the 500th anniversary of the death of Hernan Ruiz I.It is important that tribute be paid to this great master who proved capable of adapting his architectural style to the changes that took place during the transition from the fifteenth to the sixteenth century, and ensure that the spirit and culture that made Cordoba stand out as the Umayyad capital of Al-Andalus live on.Today we can say that Hernan Ruiz I rests next to his life's work in the transept of the main church of Cordoba.
