Note 376 — CANTO XI.
James Romanes Sibbald translation
Pope Anastasius: The second of the name, elected Pope in 496. Photinus, bishop of Sirenium, was infected with the Sabellian heresy, but he was deposed more than a century before the time of Anastasius. Dante follows some obscure legend in charging Anastasius with heresy. The important point is that the one heretic, in the sense usually attached to the term, named as being in the city of unbelief, is a Pope.
