Happy Easter! Here's a bit of Christian history...
This bust was part of the British Museum's "Egypt: faith after the pharaohs" exhibition and is now back on general display.
Egypt, about AD 14–20.
"This statue of Germanicus, great-nephew of the emperor Augustus, was probably made around AD 19, shortly after a visit to Egypt. Years later someone inscribed a cross on his forehead and it was hacked across the nose, ear and neck. We don’t know why the cross was added – perhaps to neutralise spirits thought to dwell in images, to ‘Christianise’ Germanicus, or to mark him as a ‘slave of God’ – as some Christians marked themselves."
