[346] _By other cares, etc._: It is not in Inferno that Dante is to hold converse with celestial intelligences. The angel, like Beatrice when she sought Virgil in Limbo, is all on fire to return to his own place. [347] _Arles_: The Alyscampo (Elysian Fields) at Arles was an enormous cemetery, of which ruins still exist. It had a circumference of about six miles, and contained numerous sarcophagi dating from Roman times. [348] _Pola_: In Istria, near the Gulf of Quarnaro, said to have contained many ancient tombs. [349] _Lords of heresies_: 'Heresiarchs.' Dante now learns for the first time that Dis is the city of unbelief. Each class of heretics has its own great sepulchre. [350] _More or less of heat_: According to the heinousness of the heresy punished in each. It was natural to associate heretics and punishment by fire in days when Dominican monks ruled the roast. [351] _Dexter hand_: As they move across the circles, and down from one to the other, their course is usually to the left hand. Here for some reason Virgil turns to the right, so as to have the tombs on the left as he advances. It may be that a special proof of his knowledge of the locality is introduced when most needed--after the repulse by the demons--to strengthen Dante's confidence in him as a guide; or, as some subtly think, they being now about to enter the abode of heresy, the movement to the right signifies the importance of the first step in forming opinion. The only other occasion on which their course is taken to the right hand is at _Inf._ xvii. 31. CANTO X.
