The head of this coffin is interesting – at first glance it’s a rather fine piece of work, but as you look more closely you can see it doesn’t look like it was made all in one go! The face doesn’t quite seem to match the surrounding wig, and looks rather nicer quality.
The coffin itself is inscribed for a woman called Heribsenes who lived in the 26th Dynasty, but the Met Museum’s website dates the face to the New Kingdom based on the style. So anything from 500 to 1000 years older than the rest of the piece.
But this doesn’t appear to be a modern frankenstein of a coffin – the wig is nicely shaped round the face, for instance. So this is ancient re-use: Heribsenes (or those burying her) saw this fine old coffin fragment and thought it would look rather nice on her coffin.

It’s not known where it was found, but it is now in the Met Museum, acc. no.: 33.5
