This a page on the reconstruction of this nameless mummy head, (inv. N .8643) presently in Florence. It’s a long read, but it shows the scans, and explains the whole process in detail. They firstly put the mummy through a CT scanner, then build up textured layers, the last one ‘borows’ someones face and maps the texture onto the fleshed out digital image. It’s interesting, but too long for me to post in it’s entirity. I get the impression this was on old guy wuth a grey beard when he died from the mummy, but the reconstruction looks a bit too young, and is missing the thin hair.
