Dante and the early astronomers

by M. A. Orr

The tenth and last Pit is traversed, and when the giant Antæus has lifted them down into the sorrowful pit towards which all the rest of Hell converges, the poets have nearly reached the centre of the earth. For they have been descending continually, finding a slight fall between each circle, and between the great divisions of different classes of sin, three sharp steep falls—the cliff descending to the River of blood and other circles of the violent, the precipice down which Geryon carried them to the Malebolge of Fraud, and the Dark Pit to the bottom of which Antæus conveyed them, where in the Frozen Lake treachery was punished. Last of all, at the very centre and bottom of the whole “dolorous kingdom” of Lucifer, they see its King, and Virgil says all has been seen, and it is time to depart, for Night is rising again.

Thus we see that the journey through the Inferno has taken exactly the time from one sunset to another, twenty-four hours.

Now Virgil seizes the shaggy side of the fiend, while the monstrous wings are raised, and with Dante clinging to him climbs down the side, as far as the hip; here with difficulty and labour the master turns round, so that his head is where his feet were, and climbs up, panting, so that Dante thinks they are returning. But when the ascent has been made, and both poets sit down to rest, Dante sees to his astonishment that the frozen lake is gone, the head and wings of Lucifer are gone, they are looking down upon him, and see only his legs which are directed upwards! To add to Dante’s bewilderment, Virgil now says, “Rise, for the way is long and the road is bad, and the sun has already returned to middle-tierce,” which, as we have seen, means at the time of the equinox 7.30 in the morning. Night was just beginning in the dreadful place they have so recently left, but now for the first time Virgil mentions the sun as giving them the time, and it is early morning.

The explanation is that the point which they passed with so great an effort is the exact centre of the world; they are now on its further side, and above them is the other hemisphere, where all is ocean save the island of Purgatory. Virgil explains how it was through the fall of Lucifer from Heaven that all the land except Purgatory is in one hemisphere, and that there is a cavity through which they may now climb to the opposite hemisphere. When Lucifer fell, all the land which then existed in the unknown hemisphere fled for fear of him, sinking under the sea, and then escaping round the globe settled in the inhabited hemisphere. It may be, he adds, that then the earth in the interior fled away from him upwards to form land in this hemisphere (Purgatory) and thus an empty space is left here. Up this, which is the same length as the tunnel of the Inferno, they climb, guided through the darkness by the sound of a little brook which has worn its winding way down the rock. On this route there is nothing to detain them, for they are alone in the darkness, but it presumably takes much longer to ascend than it did to descend, for climbing without a pause it takes about twenty-three hours (from the centre) to reach that round hole in the rocks through which at last they once more see the stars, just before the dawn of a new day.

3. PURGATORY.

Leaving Earth’s centre at sunset by Jerusalem time, sunrise by Purgatory time, the poets emerge next morning by starlight when the morning star is making all the orient smile. Henceforth Dante does not need to be told how moon or stars are standing in the sky: he has but to look up, and see the sun and sometimes the moon by day, the stars and sometimes the moon by night. The Inferno was like one long dark night, Paradise will be one brilliant day; in Purgatory the sun rises four times and sets three times, before Dante reaches the summit, and thence rises to Paradise with Beatrice.

“Lo bel pianeta che ad amar conforta”[461] is of course Venus: if there were any doubt about this, the words used concerning the dawn of the last morning on the Mountain would solve it, for there “Cytherea” is spoken of as shining in the east on the mountain. She is in Pisces, the sign which rises about two hours before Aries, or 4 a.m. at this season, and as the stars are still clearly visible, it is about 5 a.m. The poets have evidently come up from the subterranean passage facing east, for they see Venus first, then Dante turns to his right (south) and sees the four brilliant stars near the south pole, then turning towards the north pole he sees that the Wain has disappeared beneath the horizon, and close beside him he finds Cato, on whose face the Four Stars are shining. Cato tells them that the sun, which is about to rise, will be their guide to reach the Mountain, and as they first go down to the shore, following his instructions, daylight begins to appear.

While they are still on the shore the sun reaches the point just below the horizon, for he is described as just touching the western horizon of the other hemisphere, whose zenith is above Jerusalem, and night is just rising on the eastern horizon of that hemisphere. Where the poets are the rose colour in the east is turning to orange, just before the sun rises. It rises over their horizon while they are watching a light far over the sea, which with almost incredible rapidity draws near, becomes visible as a vessel, touches land, the spirits disembark, and the celestial pilot “sen gì, come venne, veloce.”[462] The sun has now driven Capricorn from the mid sky with his bright beams, that is, the stars have become invisible in bright daylight, and [fig. 46] shows that when Aries rises over the eastern horizon Capricorn will be overhead. But the sun is still very low, so swift was the coming of the spirits, for Dante’s shadow is not yet visible to them: it is by his breathing that they perceive he is a living man. It is only after the meeting with Casella, and the dispersal of the spirits by Cato, that the sun, still red with sunrise tints, makes Dante’s shadow fall in front of him as the poets are walking westward towards the mountain. He is alarmed not to see Virgil’s shadow on the ground beside it, and is told that the body within which Virgil once had cast a shadow lies buried in a country where it is now the time of vespers. That is, in Italy it is three o’clock in the afternoon: hence in Purgatory, where they now are, it is six in the morning.
