yeah, faust was based on Dante, the real dante fell in love with a girl he met, at a dinner party his family had, at a young age, about 12 years old, and he spent all the extra time he had with her, and when were old enough they got married, but the girl fell very ill and died when she was 21, this sent dante into a deep depression and he did what all depressed people do, he wrote poetry and became one of the greats of his time, in this time he wrote the "enfierno" (which means "in hell" in latin) which was later turned into the inferno by the english, it was a epic poem that chronicled the main characters travel through hell to try to get to heaven, whats funny is that the main characters name was dante and he was a great poet in life. then later on he wrote the pergatorium which was dantes travels through peragatory, and after that he wrote a book on Dantes travel into heaven, the three books were called the divine comody.
but like i said faust's back story was based on dantes life, they both fell in love at a young age, both married the girl they fell in love with and both girls died at a young age, but dante became a poet and faust became a necromancer
