A damaged and badly weathered stone head, discovered prior to 1823 in York, and interpreted as an early portrait of the emperor Constantine I, is here re-examined and identified as a modified image of an earlier, deified emperor, almost certainly Hadrian. A re-analysis of the image as it survives today further suggests that the recarving, into a likeness of Constantine, occurred after a.d. 312 and not, as widely believed, at the moment of Constantine's proclamation as emperor in York in a.d. 306.

Two damaged, weathered marble portraits, both discovered in the 1780s at opposite ends of Roman Britain, one at Bosham in West Sussex, the other at Hawkshaw in Peeblesshire, are here re-examined and identified as portraits of the emperor Trajan. The Bosham head is interpreted as a post-mortem image of the deified Trajan set up at the margins of Chichester Harbour, probably during the visit to Britain by the emperor Hadrian in the early a.d. 120s. The Hawkshaw portrait of Trajan appears to have been refashioned from a likeness of Domitian and may originally have been part of a monument created to celebrate and commemorate the total conquest of Britain, in the early a.d. 80s, which was decapitated and buried during a period of unrest on the northern frontier.
