The BBC reports:
Dante died in 1321 shortly after finishing Paradise, the last book of the Divine Comedy.
His bones were moved to the northern town of Ravenna in 1509 by monks who feared they might be stolen from his home town.
The face has been modelled from measurements taken of the skull when the crypt was opened in the 1920s.
The measurements are thought to be correct but the
jawbone, which was missing from the crypt, has been engineered to fit
the skull.
Hey, I'll mail you my copy in exchange for some book you'd think I'd like. If you're interested shoot me an email; chuber@mirus-group.com
Alex, I think the extrapolate from the little bone at the top of the nose, which would give the angle, and the surrounding bones, which would give the width and length. I'll check it out. It's an interesting question, especially since this is done so frequently in forensic reconstructions.
