When reaching the Sixth Circle of Hell, Dante and Virgil see heretics who are condemned to eternity in flaming tombs. Here, Dante talks with a couple of Florentines – Farinata degli Uberti and Cavalcante de’ Cavalcanti – but he also sees other notable historical figures including the ancient Greek philosopher Epicurus, Holy Roman Emperor Frederick II, and Pope Anastasius II. The latter, however, is according to some modern scholars condemned by Dante as a heretic by mistake. Instead, as some scholars argue, the poet probably meant the Byzantine Emperor Anastasius I.
