References to Averroes appear in the popular culture of both the western and Muslim world. The poem The Divine Comedy by the Italian writer Dante Alighieri, completed in 1320, depicts Averroes, "who made the Great Commentary", along with other non-Christian Greek and Muslim thinkers, in the first circle of hell around Saladin. The prologue of The Canterbury Tales (1387) by Geoffrey Chaucer lists Averroes among other medical authorities known in Europe at the time. Averroes is depicted in Raphael 's 1501 fresco The School of Athens that decorates the Apostolic Palace in the Vatican, which features seminal figures of philosophy. In the painting, Averroes wears a green robe and a turban, and peers out from behind Pythagoras, who is shown writing a book.
