The Silchester ‘Nymphaeum’

ABSTRACTA carved coping stone found on the site of a spring near the amphitheatre, Silchester, and first reported in 1873, was rediscovered in 2014. It does not compare in its carved detail with coping stones from the amphitheatres at Chester and London, nor with that recovered from the West Gate, Silchester, in 1890; nor does its basal width correspond with that of the arena wall of the Silchester amphitheatre. It is likely to have formed part of a monumental basin, similar to that found at Coventina's Well, Northumberland, and to have commemorated the location of a spring and its associated (unknown) deity. Similarity with the type and decoration of architectural stone used in the construction of the forum-basilica suggests a Hadrianic–Antonine date.

Vertical exploration and dimensional modularity in mice

Exploration is a central component of animal behaviour studied extensively in rodents. Previous tests of free exploration limited vertical movement to rearing and jumping. Here, we attach a wire mesh to the arena wall, allowing vertical exploration. This provides an opportunity to study the morphogenesis of behaviour along the vertical dimension, and examine the context in which it is performed. In the current set-up, the mice first use the doorway as a point reference for establishing a borderline linear path along the circumference of the arena floor, and then use this path as a linear reference for performing horizontal forays towards the centre (incursions) and vertical forays on the wire mesh (ascents). Vertical movement starts with rearing on the wall, and commences with straight vertical ascents that increase in extent and complexity. The mice first reach the top of the wall, then mill about within circumscribed horizontal sections, and then progress horizontally for increasingly longer distances on the upper edge of the wire mesh. Examination of the sequence of borderline segments, incursions and ascents reveals dimensional modularity: an initial series (bout) of borderline segments precedes alternating bouts of incursions and bouts of ascents, thus exhibiting sustained attention to each dimension separately. The exhibited separate growth in extent and in complexity of movement and the sustained attention to each of the three dimensions disclose the mice's modular perception of this environment and validate all three as natural kinds.

Excavations on the Sites of the Amphitheatre and Forum-Basilica at Silchester, Hampshire: an Interim Report

A research excavation was commenced on the site of the basilica which forms the western side of the forum of Calleva Atrebatum (Silchester, Hants) in IQ80. Its aim is to examine the Late Iron Age and early Roman occupation which, despite extensive Victorian excavations, was preserved beneath the masonry basilica. So far there is evidence of the Iron Age sequence dating back to the last quarter of the first century B.C.; it ends with the construction of a palisade dating to about the time of the Roman conquest. Two major phases of Roman timber building have been recorded, of which the later consists of a large basilica, interpreted as part of a forum-basilica and of Flavian date. The masonry basilica dates to the early second century. From the mid third until the later fourth century the basilica was given over to metalworking. The amphitheatre, with its well-preserved earthen seating banks, was first constructed during the third quarter of the first century A.D., when the seating, arena wall and entrance passages were built of timber. After several phases of repair the arena wall and entrance passages were rebuilt in stone in the first half of the third century. The full plan of this phase has been recovered; it consists of two opposing entrances on the long axis and two apsidal recesses on the short axis. The monument enjoyed a brief period of reuse in the twelfth and early thirteenth centuries.
