A cache of Roman copper-alloy fragments was discovered, apparently carefully layered in a pit, in a field in Gloucestershire by metal-detectorists in 2017. The assemblage comprises over 5 kg of metal pieces, predominantly box fittings, but also smaller items of personal use such as a fourth-century belt buckle, a three-strand bracelet, a spoon and a coin (a nummus of Crispus). Most remarkable are the sculptural fragments, including several pieces of life-size statuary and the complete statuette of a dog with fine incised decoration, and part of an incised bronze inscription panel. This article considers the original form of the statuary and the use and deposition of the cache. It is proposed that these fragments represent the remains of the accoutrements of a temple or shrine in the local area, perhaps dedicated to Diana Venatrix, and that they were removed and deposited together in the late fourth century. Supplementary material is available online (https://doi.org/10.1017/S0068113X20000501) and comprises additional figures.
Clinical Enterobacteriacae isolates with a colistin minimum inhibitory concentration (MIC) ≥4 mg/L from a United States hospital were screened for the mcr-1 gene using real-time polymerase chain reaction (RT-PCR) and confirmed by whole-genome sequencing. Four colistin-resistant Escherichia coli isolates contained mcr-1. Two isolates belonged to the same sequence type (ST-632). All subjects had prior international travel and antimicrobial exposure.
The limestone sculpture of an eagle firmly clasping a serpent in its beak was recovered from within the eastern Roman cemetery of London on the last day of excavations at 24–26 Minories, EC3 in September 2013. The sculpture, which is dated stylistically to the late first or early second century a.d., had been carefully buried within the backfill of a roadside ditch no later than the mid-second century. The Minories eagle is one of the finest and earliest examples of freestone sculpture from the London cemeteries and presumably adorned the tomb of a rich and important individual or family located nearby. Petrological analysis of the sculpture has revealed it is carved from oolitic limestone quarried from the south Cotswolds. The article presents the context of the findspot and a detailed description of the eagle sculpture with an in-depth discussion of the iconography of the image and the results of the petrological examination. The Supplementary Material available online (http://journals.cambridge.org/bri) presents an account of the site stratigraphy, integrated with the specialist finds and the environmental reports.
Situated in the borderlands of Southeast Europe, this essay explores how enduring patterns of transregional circulation and cosmopolitan sensibility unfold in the lives of dervish brotherhoods in the post-Cold War present. Following recent debates on connected histories in post-colonial studies and historical anthropology, long-standing mobile and circulating societies, and reinvigorated interest in empire, this essay focuses ethnographically on how members of a dervish brotherhood in Bosnia-Herzegovina cultivate relations with places, collectivities, and practices that exist on different temporal, spatial and geopolitical scales. These connections are centered around three modes of articulation—sonic, graphic, and genealogical—through which the dervish disciples imagine and realize transregional relations. This essay begins and concludes with a meditation on the need for a dialogue between ethnography and transregional history in order to appreciate modes of identification and imagination that go beyond the essentializing forms of collective identity that, in the post-imperial epoch, have been dominated by political and methodological nationalism.
Excavations to the east of the Roman fort of Inveresk in 2010 partly uncovered remains of a Mithraeum — the first from Scotland and the earliest securely dated example from Britain. A large rectangular sunken feature with lateral benches contained two altars buried face down at its north-western end. One was dedicated to Mithras, with iconography of both Mithras and Apollo as well as libation vessels. The other was dedicated to Sol, with a frieze above showing the Four Seasons. The Sol altar had a recess in the rear for a light which would have shone through his pierced rays, eyes, mouth and nose. Remains of an iron rod behind the nose hint at a more complex arrangement to create special visual or acoustic effects. Paint and plaster traces were recorded on both altars. The dedicator, G(aius) Cas(sius) Fla(…), a centurion, may have been in command of the garrison or of a legionary detachment. Stylistic links, especially in letter form, connect the work to sculptors of Legio XX. The stones and pigments are most likely from local sources. Little of the setting could be explored but there were traces of a precinct. A pit beside the Mithraeum included a large part of a well-used fineware beaker, which represented a deliberate offering. The Supplementary Material available online (http://journals.cambridge.org/bri) contains detailed descriptions of the altars, observations on the stone-working technology, lithology and pigment analysis, with extensive illustrations.
A hoard of objects found at the early Roman colony at Colchester in a small hole scraped into the floor of a house destroyed during the Boudican revolt includes a group of high-quality gold jewellery, three silver military awards, a bag of coins, an unusual silver-clad wooden box and other items. Buried in haste as the British approached, they provide a remarkably clear image of one couple's background, achievements, taste and social standing. A bulla shows that the man was a Roman citizen, the awards that he was a veteran soldier of some distinction, while parallels for the woman's jewellery suggest that it was acquired in Italy.
Advancement of ion acceleration by intense laser pulses is studied with ultra-thin nanometer-thick diamond like carbon and micrometer-thick Titanium target foils. Both investigations aim at optimizing the electron density distribution which is the key for efficient laser driven ion acceleration. While recently found maximum ion energies achieved with ultra-thin foils mark record values micrometer thick foils are flexible in terms of atomic constituents. Electron recirculation is one prerequisite for the validity of a very simple model that can approximate the dependence of ion energies of nanometer-thick targets when all electrons of the irradiated target area interact coherently with the laser pulse and Coherent Acceleration of Ions by Laser pulses (CAIL) becomes dominant. Complementary experiments, an analytical model and particle in cell computer simulations show, that with regard to ultra-short laser pulses (duration ~45 fs at intensities up to 5 × 1019 W/cm2) and a micrometer-thick target foil with higher atomic number a close to linear increase of ion energies manifests in a certain range of laser intensities.
In this paper we report on an experimental study of high harmonic radiation generated in nanometer-scale foil targets irradiated under normal incidence. The experiments constitute the first unambiguous observation of odd-numbered relativistic harmonics generated by the v × B component of the Lorentz force verifying a long predicted property of solid target harmonics. Simultaneously the observed harmonic spectra allow in-situ extraction of the target density in an experimental scenario which is of utmost interest for applications such as ion acceleration by the radiation pressure of an ultraintense laser.
