[5] Constance, daughter of the king of Sicily, Roger 1.; married, in 1186, to the Emperor, Henry VI., the son of Frederick Barbarossa, and father of Frederick II, who died in 1250, the last Emperor of his line. Thus she spoke to me, and then began singing “Ave Maria,” and Singing vanished, like a heavy thing through deep water. My sight, that followed her so far as was possible, after it lost her turned to the mark of greater desire, and wholly rendered itself to Beatrice; but she so flashed upon my gaze that at first the sight endured it not: and this made me more slow in questioning. CANTO IV. Doubts of Dante, respecting the justice of Heaven and the abode of the blessed, solved by Beatrice.—Question of Dante as to the possibility of reparation for broken vows. Between two viands, distant and attractive in like measure, a free man would die of hunger, before he would bring one of them to his teeth. Thus a lamb would stand between two ravenings of fierce wolves, fearing equally; thus would stand a dog between two does. Hence if, urged by my doubts in like measure, I was silent, I blame not myself; nor, since it was necessary, do I commend. I was silent, but my desire was depicted on my face, and the questioning with that far more fervent than by distinct speech. Beatrice did what Daniel did, delivering Nebuchadnezzar from anger, which had made him unjustly cruel, and said, “I see clearly how one and the other desire draws thee, so that thy care so binds itself that it breathes not forth. Thou reasonest, 'If the good will endure, by what reckoning doth the violence of others lessen for me the measure of desert?' Further, it gives thee occasion for doubt, that the souls appear to return to the stars, in accordance with the opinion of Plato.[1] These are the questions that thrust equally upon thy wish; and therefore I will treat first of that which hath the most venom.[2] [1] Plato, in his Timaeus (41, 42), says that the creator of the universe assigned each soul to a star, whence they were to be sown in the vessels of time. “ He who lived well during his appointed time was to return to the star which was his habitation, and there he would have a blessed and suitable existence.” Dante's doubt has arisen from the words of Piccarda, which implied that her station was in the sphere of the Moon. [2] The conception that the souls after death had their abode in the stars would be a definite heresy, and hence far more dangerous than a question concerning the justice of Heaven, for such a question might be consistent with entire faith in that justice.
