Excavation of the latest surviving structures of the villa at Batten Hanger in West Sussex indicates that a large aisled building was demolished in the late fourth or fifth century and replaced by a large hall 31.6 m long by 11.5 m wide, orientated approximately east–west. The survival of pad stones shows this space to have been divided into seven bays, with the more westerly bays screened off by a cross wall. The east wall of the building had collapsed outwards and was largely complete. A coin of Valentinian III suggests that occupation continued at least to the middle of the fifth century. The Supplementary Material available online (http://journals.cambridge.org/bri) contains a detailed presentation of the coin hoard and the pottery assemblages.

The origin of the English is an interesting problem – and not only for them. In one short century, the evidence from texts, burial, artefacts, stable isotopes and now DNA provides several different answers to the question of whether England was invaded by Germans in the fifth century and if so in what manner. The rigorous approach by our authors tips the balance back in favour of a population changing its cultural allegiance – rather than being physically overwhelmed – but, as they emphasise, any new reading must depend on a very high level of archaeological precision – perhaps only now coming within reach.
