Ninety-five-year-old Doris Held, a great niece of Sigmund Freud, has been convening the Shakespeare Reading Group in Northampton, Massachusetts, my hometown, since she moved here in 2016. In the following essay, which is a personal response to my experience of this group of Shakespearean readers, to Doris Held, and to the work of Shakespeare in general, I attempt to chart the full impact of the Bard’s work on my life and on the world around me. I am neither a scholar nor a historian. In a true sense, I am a bystander Shakespearean, who has received deep reward and benefit from the experience, but it is Doris Held and her group who opened my eyes to the precise nature of this unexamined reward. Doris brought the spirit of the group from Cambridge, Massachusetts, where she had been a dues-paying member for decades of something called the Old Cambridge Shakespeare Association, which itself dates to 1880. My wife Debra and I attended the first meeting in Northampton more than a decade ago, and we have been receiving emails from Doris four times a year ever since. While these communications often induce guilt, they invariably lead to pleasures that I would never want to relinquish. That is a complicated dynamic in my routine, and I try to grapple with its ebb and flow in the pages that follow. Each time I get one, I have a version of the same conversation in my head. Is Doris still doing this? Haven’t they done all the plays by now? All things considered, wouldn’t they—and I—rather be home watching a true crime documentary about Gaby Petito on Netflix? What the hell is William Shakespeare to me anyway? At this point, if I’m honest, Shakespeare is Doris. The experience with this group led me in two directions. One took me back to my now long-ago history with Shakespeare’s work as an actor in college. The other took me via historical research into the prehistory of Doris Held’s previous Shakespeare group in Cambridge, Massachusetts. The two paths gave me a deeper grasp of the influence of his work across the world and on my own life. Full article

In 44 BC, Julius Caesar established Colonia Laus Iulia Corinthiensis, strategically reviving Corinth to dominate Isthmian trade routes and extend Rome’s commercial influence eastwards. At the centre of the colony lies Temple E, an enigmatic structure with an unidentified associated cult. This study investigates the architectural characteristics of Temple E, focusing on the use of marble as the primary building material. Petrographic analysis, elemental chemical profiling (Mn, Mg, Fe, Sr, Y, V, Cd, La, Ce, Yb, U), and isotopic measurements (δ¹⁸O ‰, δ¹³C ‰) are employed to analyse marble samples from the surrounding region, exploring sourcing and construction practices. Statistical comparisons with ancient quarry databases indicate a strong reliance on locally sourced Doliana marble, underscoring the economic significance of regional quarries and suggesting the existence of a local workshop dedicated to architectural production in Roman Corinth. By integrating geological and archaeometric approaches, this study highlights Corinth’s pivotal role in the regional marble trade and its broader economic importance during the Roman Imperial period. The findings emphasise the use of local resources, illustrating a flourishing marble-working industry and enhancing our understanding of the relationship between local materials and Roman architectural practices.

As part of a long-term campaign to document, study, and conserve the Heroes tapestries from The Cloisters collection at The Metropolitan Museum of Art, organic colorant analysis of Julius Caesar (accession number 47.101.3) was performed. Analysis with liquid chromatography–quadrupole time-of-flight mass spectrometry (LC-qToF-MS) revealed the presence of several multiply chlorinated xanthones produced only by certain species of lichen. Various lichen dye sources have been documented in the literature for centuries and are classified as either ammonia fermentation method (AFM) or boiling water method (BWM) dyes based on their method of production. However, none of these known sources produce the distinctive metabolites present in the tapestry. LC-qToF-MS was also used to compare the chemical composition of the dyes in the tapestry with that of several species of crustose lichen. Lichen metabolites, including thiophanic acid and arthothelin, were definitively identified in the tapestry based on comparison with lichen xanthone standards and a reference of Lecanora sulphurata, confirming the presence of a lichen source. This finding marks the first time that lichen xanthones have been identified in a historic object and the first evidence that BWM lichen dyes may have been used prior to the eighteenth century.

Texture surface containing both micro-pits and a thin carbon coating was produced using laser surface texturing and magnetic-control vacuum sputtering. Tribological properties of the laser-textured surface coated with thin carbon were experimentally investigated at low-temperature (8–10 °C) under starved and lubricated conditions with a ring-on-ring test rig. The results indicated that the laser-textured surface combined with carbon coating (textured + coating) exhibited low wear intensity and friction coefficient under lubricated conditions, while moderate wear was observed under starved lubrication conditions as compared with the smooth, textured, and carbon-coated surfaces. The wear mechanisms of the lubricated, textured, coated surface under three working conditions (10 N and 1.25 m/s, 16 N and 0.25 m/s, and 50 N and 0.05 m/s) revealed plowing effect, corrosion, and adhesive wear, while oxidative and adhesive wears were observed under starved lubrication. Finally, the textured, coated surface was freely adaptable to different working conditions and exhibited additional effects for better tribological applications at low-temperature as compared with the smooth, laser-textured, and carbon-coated surfaces.

Metaphors move—and displace—people. This paper starts from this premise, focusing on how elites have deployed metaphors of water and waste to form a rhetorical consensus around the displacement of non-elite citizens in ancient Roman contexts, with reference to similar discourses in the contemporary Global North and Brazil. The notion of ‘domestic displacement’—the forced movement of citizens within their own sovereign territory—elucidates how these metaphors were used by elite citizens, such as Cicero, to mark out non-elite citizens for removal from the city of Rome through colonisation programmes. In the elite discourse of the late Republican and early Augustan periods, physical proximity to and figurative equation with the refuse of the city repeatedly signals the low social and legal status of potential colonists, while a corresponding metaphor of ‘draining’ expresses the elite desire to displace these groups to colonial sites. The material outcome of these metaphors emerges in the non-elite demographic texture of Julius Caesar’s colonists, many of whom were drawn from the plebs urbana and freedmen. An elite rationale, detectable in the writings of Cicero, Livy, Dionysius of Halicarnassus, and others, underpins the notion of Roman colonisation as a mechanism of displacement. On this view, the colony served to alleviate the founding city—Rome—of its surplus population, politically volatile elements, and socially marginalised citizens, and in so doing, populate the margins of its empire too. Romulus’ asylum, read anew as an Alban colony, serves as one prototype for this model of colonisation and offers a contrast to recent readings that have deployed the asylum as an ethical example for contemporary immigration and asylum seeker policy. The invocation of Romulus’ asylum in 19th century debates about the Australian penal colonies further illustrates the dangers of appropriating the asylum towards an ethics of virtue. At its core, this paper drills down into the question of Roman colonists’ volition, considering the evidence for their voluntary and involuntary movement to a colonial site and challenging the current understanding of this movement as a straightforward, series of voluntary ‘mass migrations’. In recognising the agency wielded by non-elite citizens as prospective colonists, this paper contends that Roman colonisation, when understood as a form of domestic displacement, opens up another avenue for coming to grips with the dynamics of ‘popular’ politics in the Republican period.

History contains many accounts of speeches given by civic and military leaders before large crowds prior to the invention of electronic amplification. Historians have debated the historical accuracy of these accounts, often making some reference to acoustics, either supporting or refuting the accounts, but without any numerical justification. The field of digital humanities, and more specifically archaeoacoustics, seeks to use computational techniques to provide empirical data to improve historical analysis. Julius Caesar recalled giving speeches to 14,000 men after the battle of Dyrrachium and another to 22,000 men before the battle of Pharsalus during the Roman Civil War. Caesar’s background and education are discussed, including his training in rhetoric and oratory, which would have affected his articulation and effective sound pressure level while addressing his troops. Based on subjective reports about Caesar’s oratorical abilities, his effective Sound Pressure Level (SPL) is assumed to be 80 dBA, about 6 dB above the average loud speaking voice but lower than that of the loudest trained actors and singers. Simulations show that for reasonable background noise conditions Caesar could have been heard intelligibly by 14,000 soldiers in a quiet, controlled environment as in the speech at Dyrrachium. In contrast, even granting generous acoustic and geometric conditions, Caesar could not have been heard by more than about 700 soldiers while his army was on the march before the battle of Pharsalus.

The breakwater construction technique using floating concrete caissons is well-known nowadays as a widespread system. Yet do we really know its origin? Since Julius Caesar used this technology in Brindisi (Italy) up to the Normandy landings in June 1944, not only has this technology been developed, but it has been a key item in several moments in history. Its development has almost always been driven by military requirements. The greatest changes have not been conceptual but point occurring, backed by the materials used. Parallelisms can be clearly seen in each new stage: timber, opus caementitium (Roman concrete), iron and concrete… However, nowadays, achieving a more sustainable world constitutes a major challenge, to which the construction of caissons breakwaters must contribute as a field of application of new eco-friendly materials. This research work provides a general overview from the origins of caissons until our time. It will make better known the changes that took place in the system and their adaptation to new materials, and will help in clarifying the future in developing technology towards composite sustainable materials and special concrete. If we understand the past, it will be easier to define the future. Full article

The core technique of electric storage water heaters is the manufacture of the tanks, and the welding technique is the key technology of the tank manufacture. A company producing water heaters received feedback from its after-sales that a large quantity of water leakage from the tanks was found in the market. A follow-up on the manufacturing site by the researchers showed that the position of the water leakage defects mostly happens in the welds of the tanks. Series of experiments were conducted to investigate the mechanical properties, residual stress, and diffusible hydrogen content of the longitudinal weld of the tank. Results of the mechanical properties showed that both the micro-hardness and the tensile strength of the welds are higher than the base metal. There are higher residual compressive stresses in the weld center and the adjacent-weld zone. Vertical residual compressive stress decreases first and then increases (149 MPa–28 MPa–134 MPa) from the weld ends to the middle, whilst the transversal stress decreases continuously (332 MPa~240 MPa) from the weld center to the heat affected zone. After enameling, the longitudinal welds’ peak micro-hardness of coarse grained region reduces by 30.9 HV1, and the average micro-hardness of the HAZ reduces by 5 HV1. The average vertical residual compressive stress difference of the same test points reduces from 270.6 MPa to 20.4 MPa. It proves that enameling can improve the mechanical property of the longitudinal welds. Full article

There is comprehensive work on the tribological properties and lubrication mechanisms of oil lubricant used on textured surfaces, however the use of grease lubrication on textured surfaces is rather new. This research article presents an experimental study of the frictional behaviours of grease lubricated sliding contact under mixed lubrication conditions. The influences of surface texture parameters on the frictional properties were investigated using a disc-on-ring tribometer. The results showed that the friction coefficient is largely dependent on texture parameters, with higher and lower texture density resulting in a higher friction coefficient at a fixed texture depth. The sample with texture density of 15% and texture depth of 19 μm exhibited the best friction properties in all experimental conditions because it can store more grease and trap wear debris. The reduction of friction is mainly attributable to the formation of a stable grease lubrication film composed of oil film, transfer film and deposited film, and the hydrodynamic pressure effect of the surface texture, which increases the mating gap and reduces the probability of asperity contact. This result will help in understanding the tribological behaviour of grease on a textured surface and in predicting the lubrication conditions of sliding bearings for better operation in any machinery.
