Fotis Kontoglou (1895–1965) was a prominent Greek painter and writer, known primarily for revitalizing byzantine painting in the 20th century and being one of the first artist-conservators in Greece active at this period. The current study represents the first systematic attempt to examine seven (7) icons (i.e., ecclesiastical panel paintings) attributed to Kontoglou, currently located in two famous monasteries in Laconia, Greece. The research utilized exclusively non-destructive analytical techniques, namely digital optical microscopy, UV-induced visible fluorescence photography (UVIVF), and portable X-ray fluorescence (p-XRF) spectroscopy, to identify the materials—particularly pigments—employed in the corresponding paintings. The results are interpreted under the light of Kontoglou’s own writings on painting, in particular his “Ekphrasis” painting manual. Preliminary assessments of surface morphology and state of preservation were achieved through macroscopic and microscopic probing, as well as through inspection under ultraviolet light, while further analysis was performed using portable X-ray fluorescence spectroscopy. The results confirm the employment of both traditional and modern synthetic inorganic components, while comparisons with the pigments listed in Kontoglou’s “Ekphrasis” painting manual suggest his persistent use of a rather limited palette of pigments. Nevertheless, despite the fact that the paintings were executed in a small period of time (1954–1956), data revealed notable differentiation between the studied icons, which probably indicates procurement of materials from various sources. Given the scarcity of technical investigations of modern (20th century) paintings, this study is relevant and reveals some interesting hints, which may pertain to the trends of the mid-20th century Greek paint market, like, e.g., the rather limited distribution of Ti-white. Additionally, the current findings contribute considerably towards understanding Kontoglou’s artistic methods during a highly creative period and can be utilized to support future conservation efforts. Ultimately, the current preliminary study sheds light on some methodological aspects of the pertinent research and assists towards establishing a detailed protocol for future studies. Full article

Thin gold leaves were frequently used to embellish post-Byzantine religious panel paintings. Measuring their thickness using non-destructive methods is essential for understanding the technology behind their creation and developing effective preservation strategies. This study describes a method for non-invasively measuring the thickness of these gildings using large-scale imaging micro-X-ray fluorescence (µ-XRF) spectroscopy. The method relates the intensity of the Au Lα X-ray characteristic transition to the thickness of the gold layer. The method offers precise measurements of gold layer thickness in the submicrometer range on gilded surfaces, while traditional methods based on the intensity ratio of the same element prove ineffective. The method was initially validated on a mock-up sample created using traditional gilding techniques. Subsequently, the gilding was examined on two case studies of Greek religious icons. The analysis accurately measured the thickness of individual gold leaves, approximately one hundred nanometers, and identified regions with multiple overlapping layers, corresponding to structures with up to four leaves. The findings confirm that this technique offers valuable quantitative insights into the materiality and artistic techniques of these cultural heritage artifacts. Full article

Religious panel paintings (icons) play a pivotal role in the rituals of the Eastern Orthodox Christian Church. However, their continuous use often results in physical degradation, prompting remedial interventions. Quite commonly, alterations were treated by simply applying new paint layers directly over the decayed original, while in some cases, old icons were overpainted merely as a means to renovate and modernize them. Therefore, numerous overpainted icons are currently housed in churches, museums, and private collections across Greece. This study focuses on the investigation of a post-Byzantine icon of Christ Pantokrator, which displays extensive overpainting while retaining a few visible fragments of the original composition. The objective was to assess the extent and condition of preservation of the original artwork, to identify materials and techniques used both in the initial painting and in subsequent restoration phases, and to distinguish between those phases. To achieve these aims, a fully non-invasive diagnostic methodology was implemented, including visible light photography, ultraviolet radiation imaging (UVR/UVL), hyperspectral imaging (MuSIS HS), infrared reflectography (IRRef), X-ray radiography, and macroscopic X-ray fluorescence scanning (MA-XRF). The findings confirm that the original painting remains substantially preserved and is of high artistic quality. Moreover, analysis revealed at least two distinct phases of overpainting, likely dating from the 20th century, while the results suggest that the original artwork probably dates to the first half of the 18th century. The study highlights the need to use complementary techniques in order to non-invasively assess complex artifacts like overpainted icons and offers valuable insights into historical restoration practices providing foundation for future conservation planning.

In the early 1470s, Venetian artist Gentile Bellini painted Basilios Bessarion kneeling in front of the precious Byzantine reliquary that Bessarion donated to the Venetian Scuola di Santa Maria della Carità. This painting functioned as the cover to the tabernacle where the reliquary was stored. Rather than accurately depicting the sacred object, Bellini’s painting reworks the appearance of the reliquary in relation to the figures in the painting and reveals a disjunction between the relic and its cover. The reliquary becomes a somber, monumental object that has more presence as a looming entity than as a combination of parts and histories. This paper positions Bellini’s painted enclosure for the reliquary as a product of the blending of Venetian and Byzantine devotional practices and sacred objects. Bessarion’s reliquary was an aggregate object, and Bellini’s painting continues the reframing of Bessarion’s reliquary to serve as a visual contract of the connection between Bessarion and the Scuola di Santa Maria della Carità and, more broadly, Byzantium and Venice. Bellini’s painting ultimately seeks to capture the sacred mystique associated with Byzantine Orthodoxy while also establishing the reliquary within its Venetian, confraternal present. Full article

In this article, a multidisciplinary methodological approach for studying a wooden panel painting is applied. The theoretical framework, within which this research has arisen, is the application of state-of-the-art non-destructive techniques for addressing issues concerning the constituting parts and composing materials of the artwork. Hereby, a post-Byzantine icon was studied, which was dated back to 1836. It is a painting executed on a wooden panel, with a decorated wooden frame attached. The artifact was thoroughly investigated through the application of infrared thermography (IRT), multispectral imaging (MSI), and macroscopic X-ray fluorescence spectrometry (MA-XRF). These analyses provided crucial information about the verso of the painting (i.e., the wooden panel and the frame) and allowed for the revelation of important details of the recto of the painting, which were not visible due to the presence of an old, decayed varnish. Additionally, through the detailed mapping of the distribution of various chemical elements on the recto of the painting and the frame, it was possible to identify the materials used and techniques employed. It is therefore shown that, when combined, the non-destructive methodologies in consideration can provide adequate information referring to the materiality and state of preservation of panel paintings, permitting the conservator to proceed to a tailored conservation treatment.

The interior of Orthodox churches is entirely decorated with paintings, icons, and frescoes, to help create a special environment for the prayers and visitors. The paintings have religious, esthetic, and historical value, being created in the Byzantine tradition and following recommendations on style and materials according to old church canons. Particular importance is attributed to the Iconostasis decorated with icons on several registers, as well as to polychrome wooden ornaments and imperial doors. This work presents the scientific investigation results of three royal icons, theoretically dating to the 19th century, from the Iconostasis of the Runcu church, an important 19th-century Romanian historical monument, aiming to answer questions regarding their age and constituent materials, especially what were the mineral pigments used in the color palettes for their painting and if there were any old repainting interventions, in order to assist their restoration and conservation. Methods of characterization employed were optical microscopy, SEM-EDX spectrometry, ATR/FTIR spectroscopy, and X-ray fluorescence spectrometry. Results obtained allowed us to date, attribute, and evaluate the conservation state of the Royal icons; to our knowledge, this study is among the very few research studies carried out so far on the religious heritage conservation field in Romania.

This presented research examined the wall paintings in the Church-Ossuary Presentation of the Blessed Virgin, part of the most important Rila Monastery complex in Bulgaria, painted by the painters from Mount Athos in 1795. The painting materials used to create the unique murals were studied for the first time by optical microscopy (OM), attenuated total reflectance Fourier transform infrared (ATR–FTIR), scanning electron microscopy energy dispersive X-ray spectroscopy (SEM–EDS), and enzyme-linked immunosorbent assay (ELISA). The vibrational and elemental analysis showed that the color palette of the paintings is composed of pigments traditional for Orthodox church wall paintings such as natural pigments, including yellow ochre, red ochre, green earth, and calcite, as well as other historical pigments of synthetic origin, including smalt, red lead, cinnabar, and verdigris. The analysis of the binders by the ATR–FTIR spectroscopy and enzyme-linked immunosorbent assay (ELISA) analysis implied the use of the post-Byzantine egg tempera technique. Only the blue backgrounds in the murals were painted using a smalt-based paint mixed with a carbohydrate binder. Based on the current analysis and comparison with the successive paintings in the other churches of the Rila Monastery, it could be concluded that the technology of the painting process followed by the Athonite artists during the work in the Church-Ossuary became a point of reference for many Bulgarian icon-painters later.

Since the Hellenistic period, preparatory drawings known as sinopiae were employed as guidelines for mosaicists in creating mosaics. The sinopiae served as the basis for style and content, facilitating the placement of colored tesserae in the supporting mortar. The technology of the mosaic and pigments used reflect the capacity of the mosaic workshop and its master. This work explores a polychrome sinopia that was found under a Byzantine mosaic of an Armenian Chapel in Jerusalem, by a multi-analytical characterization of mineralogical and chemical properties. The composition of the pigments in the black and red areas of the sinopia include carbon black and red ochre, respectively, utilized in the fresco technique. Since colored tesserae are placed in wet mortar, it can be deduced that mosaicists worked together with painters during the executionary steps. This has corresponding implications for historical and artistic specializations at mosaic workshops, with deeper understanding of mosaic production processes. This research also highlights the importance of studying sinopiae under floor mosaics, which is a source of information on the pigments, paintings techniques, and the people who executed the work, all embedded in mortar which is well protected below the stone tesserae.

The church of Saint Mamas is a small, domed structure that lies close to Menetes village in Karpathos. It preserves most of its painted decoration, consisting of the scene of the Ascension of Christ on the dome and saintly figures on the rest of the surfaces. A dedicatory inscription, read here for the first time, dates the frescoes to 1312/3 and places them in the broader context of precisely dated monuments. Certain features of the iconographic program, such as the presence of healer saints (Panteleemon and Kyprianos) but mostly of the officiating Pope Sylvester and the passage used in the codex of Christ Pantocrator on the apse of the altar, lead us to interesting conclusions concerning, among other things, the perception of anti-Latin propaganda in the islands of the South Aegean. Also, the stylistic affinities between the art of Karpathos and Crete corroborate the diachronic interrelations between the two islands. The church of Saint Mamas is an exceptional example and one of the few Byzantine-decorated monuments that survive on the island. Full article

Since Manolis Chatzidakis’s pivotal publications on post-Byzantine Cretan icon painting in the 1970s, research in the field is, by now, very well established. In turn, these studies have demonstrated the contribution of Venetian Crete’s artistic production to European culture. Despite Giorgio Vasari’s condemnations of the ‘Greek style’, Byzantine icons remained popular in Renaissance Europe among Western patrons. Research on Venetian Crete has greatly benefitted from the survival of its archives, presently housed in Venice (Archivio di Stato di Venezia), an incredibly rich and invaluable source of information. One of the best-known published and referenced documents from these archives, supporting the wider popularity and dissemination of Cretan icons, is a contract offered to three Cretan painters dated 4 July 1499 concerning the production and delivery of 700 icons of the Virgin in just 42 days, by 15 August 1499, the day of the feast of the Dormition of the Virgin. This paper revisits the information the famous contract provides with the aim to scrutinise it further. Full article

Traditional Serbian religious art originated in Byzantine culture and conserved Byzantine elements until modern times. However, since the end of the 17th century, many changes in traditional icon painting have been introduced. Previous studies focused on the changes in iconography and style, but very little attention was paid to the changes in painting materials and techniques. This research focuses on the blue pigments on icons from the first half of the 18th century. Eight icons with blue areas of a different hue were selected for the study. Due to its rarity in nature, price, and iconographical importance, the blue pigment was particularly praised by painters. Therefore, the choice of the blue pigment can be related to historical information to trace influences and the development of the painter’s practice. Imaging techniques, several portable, non-destructive analytical techniques, such as XRF and FTIR, followed by optical microscopy and SEM-EDX analysis of the samples were used to characterize blue pigments and the painting technique. An analysis showed that icon painters at the beginning of the 18th century used pigments such as azurite, an indigo-organic colourant of plant origin, and Prussian blue. Contrary to the traditional belief that natural ultramarine blue was used, it was not confirmed in any studied examples. Full article

In the collections of the Harvard Art Museums there is an icon of the Virgin and Child with Saints John the Baptist and Roch. Although a typical product of Cretan icon painting of the turn of the sixteenth century, the icon stands out from similar contemporary artworks due to its unusual subject matter and materiality. The iconographic analysis of the icon places it at the intersection of the Latin and Byzantine traditions and suggests that it was intended as a votive offering against the plague, featuring one of the earliest depictions of the anti-plague saint, Roch of Montpellier in Eastern Orthodox art. Examination of the verso of the icon further underscores the Western European associations of the panel. The presence of an elaborate incised design on the back side of the icon suggests that the wooden panel originated from a reused piece of furniture, in all probability, a fifteenth-century Italian chest. With this case study as a point of reference, this article discusses the commercial, artistic, and cross-confessional exchanges that took place in the ethnically and culturally pluralistic societies of Venice and its Mediterranean colonies, including the trans-confessional spread of cults, the dissemination of artistic trends, as well as the mutual transfer of artworks and objects of prestige, such as icons and chests.

The paper illustrates the results of a non-invasive characterisation of pigments and their mixtures in the pictorial surfaces of the wall paintings (10th century) found in the Byzantine church of Palazzo Simi in Bari (Italy). The investigation techniques included portable digital polarised microscopy, fibre optic reflectance spectroscopy (FORS) and X-ray fluorescence spectroscopy (XRF). Data comparison supported the recognition of red and yellow ochres, green earth, vine black, minium and Egyptian blue. The presence of some pigment mixtures demonstrated the recurrence of specific technical expedient used by local medieval artists in order to simulate more expensive pigments, which enabled contribution to the understanding of the valuable artistic tradition of the Apulian Middle Age. Both for purposes of conservation and fruition of the site, which is not always accessible, and due to the complexity in taking suitable photographs for the representation of results, the latter was performed on orthophotos extracted from a digital photogrammetric 3D model of the whole archaeological site. By means of chromatic overlapped layers, an interactive compositional map of the pictorial surfaces was produced. Full article

During the restoration work promoted by the FAI foundation (Fondo Ambiente Italiano) of the abbey of Santa Maria di Cerrate (Lecce, Apulia, South Italy), multidisciplinary analyses have been realized to support conservators and art historians for the safeguard and valorization of the most important byzantine evidence (12th–13th century) in Apulia. In this paper, mortar samples have been investigated using scanning electron microscopy (SEM-EDX) and X-ray diffraction (XRD) to characterize the observed materials, directing conservators for the integration interventions with compatible realizations. Moreover, the samples were compared with specimens taken from local quarries and the nearest coastline area, and vegetal fibers, embedded into the mortars were analyzed by applying radiocarbon dating by accelerator mass spectrometry (AMS). It was thus possible to give a contribution to the historical-artistic research related to the building techniques, the ratio aggregates/binder and the employed materials of the mortars and the dating of the mural paintings between the end of the 12th century and the first half of the 13th century.

There is growing interest in bringing non-invasive laboratory-based analytical imaging tools to field sites to study wall paintings in order to collect molecular information on the macroscale. Analytical imaging tools, such as reflectance imaging spectrometry, have provided a wealth of information about artist materials and working methods, as well as painting conditions. Currently, scientific analyses of wall paintings have been limited to point-measurement techniques such as reflectance spectroscopy (near-ultraviolet, visible, near-infrared, and mid-infrared), X-ray fluorescence, and Raman spectroscopy. Macroscale data collection methods have been limited to multispectral imaging in reflectance and luminescence modes, which lacks sufficient spectral bands to allow for the mapping and identification of artist materials of interest. The development of laboratory-based reflectance and elemental imaging spectrometers and scanning systems has sparked interest in developing truly portable versions, which can be brought to field sites to study wall paintings where there is insufficient space or electrical power for laboratory instruments. This paper presents the design and testing of a simple hyperspectral system consisting of a 2D spatial spot scanning spectrometer, which provides high spectral resolution diffuse reflectance spectra from 350 to 2500 nm with high signal to noise and moderate spatial resolution (few mm). This spectral range at high spectral resolution was found to provide robust chemical specificity sufficient to identify and map many artists’ materials, as well as the byproducts of weathering and conservation coatings across the surface of ancient and Byzantine Cypriot wall paintings. Here, we present a detailed description of the hyperspectral system, its performance, and examples of its use to study wall paintings from Roman tombs in Cyprus. The spectral/spatial image processing workflow to make maps of pigments and constituent painting materials is also discussed. This type of configurable hyperspectral system and the imaging processing workflow offer a new tool for the field study of wall paintings and other immovable heritage. Full article
