As you can see from the CGI 3D rendered reconstruction of Dante, he seems to have aged beyond his years, given that he only died at the age of 56. He was often depicted as a stern figure with a hooked nose in his portraits, however he doesn't look all that mean in the facial reconstruction, does he? In fact, the reconstruction shows a bit of a softer side to the poet and philosopher.
Dante's new face was created based on a bunch of measurements of Dante's skull, which were taken by a professor in 1920. The reconstruction was considerably kinder than any of his portraits, as he was portrayed with larger eyes, a more rounded jaw and a very gentle expression. So, not quite the monster that his aesthetic history would have us believe.
