_Canto XIII._ The second ledge of purgatory, which they have now reached, is faced with plain gray stone, and Virgil leads his companion a full mile along it ere they become aware of a flight of invisible spirits, some of whom chant "They have no wine!" while the others respond "Love ye those who have wrong'd you." These are those who, having sinned through envy, can be freed only by the exercise of charity. Then, bidding Dante gaze fixedly, Virgil points out this shadowy host, clothed in sackcloth, sitting back against the rocks, and Dante takes particular note of two figures supporting each other. He next discovers that one and all of these victims have their eyelids sewn so tightly together with wire that passage is left only for streams of penitential tears. When allowed to address them, Dante, hoping to comfort them, offers to bear back to earth any message they wish to send. It is then that one of these spirits informs Dante that on earth she was Sapia, a learned Siennese, who, having rejoiced when her country was defeated, is obliged to do penance for heartlessness. Marvelling that any one should wander among them with eyes unclosed, she inquires by what means Dante has come here, bespeaks his prayers, and implores him to warn her countrymen not to cherish vain hopes of greatness or to sin through envy. _Canto XIV._ The two spirits leaning close together, in their turn question who Virgil and Dante may be? When they hear mention of Rome and Florence, they hotly inveigh against the degeneracy of dwellers on the banks of the Tiber and Arno. Shortly after leaving this place with his guide, Dante hears the wail: "Whosoever finds will slay me," a cry followed by a deafening crash. _Canto XV._ Circling round the mountain, always in the same direction, Dante notes the sun is about to set, when another dazzling angel invites them up to the next level,--where anger is punished,--by means of a stairway less steep than any of the preceding. As they climb, the angel softly chants "Blessed the merciful" and "Happy thou that conquer'st," while he brushes aside the second _P ._, and thus cleanses Dante from envy. But, when Dante craves an explanation of what he has heard and seen, Virgil assures him that only when the five remaining "scars" have vanished from his brow, Beatrice herself can satisfy his curiosity. On reaching the third level, they find themselves enveloped in a dense fog, through which Dante dimly beholds the twelve-year-old Christ in the Temple and overhears his mother chiding him. Next he sees a woman weeping, and lastly Stephen stoned to death.
