The Symposium (Banquet of the Ten Virgins)

Thekla. Resuming then, let us first lay bare, in speaking of those things according to our power, the imposture of those who boast as though they alone had comprehended from what forms the heaven is arranged, in accordance with the hypothesis of the Chaldeans and Egyptians. For they say that the circumference of the world is likened to the turnings of a well-rounded globe, the earth having a central point. For its outline being spherical, it is necessary, they say, since there are the same distances of the parts, that the earth should be the centre of the universe, around which, as being older, the heaven is whirling. For if a circumference is described from the central point, which seems to be a circle,—for it is impossible for a circle to be described without a point, and it is impossible for a circle to be without a point,—surely the earth consisted before all, they say, in a state of chaos and disorganization. Now certainly the wretched ones were overwhelmed in the chaos of error, “because that, when they knew God, they glorified Him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened;” and their wise men said that nothing earth-born was more honourable or more ancient than the Olympians. Whence they are not mere children who know Christ, like the Greeks, who, burying the truth in fairies and fictions, rather than in artistic words, ascribing human calamities to the heavens, are not ashamed to describe the circumference of the world by geometrical theorems and figures, and explain that the heaven is adorned with the images of birds and of animals that live in water and on dry land, and that the qualities of the stars were made from the calamities of the men of old, so that the movements of the planets, in their opinion, depended upon the same kind of bodies. And they say that the stars revolve around the nature of the twelve signs of the Zodiac, being drawn along by the passage of the circle of the Zodiac, so that through their intermingling they see the things which happen to many, according to their conjunctions and departures, their rising and setting.

For the whole heaven being spherical, and having the earth for its central point, as they think, because all the straight lines from the circumference falling upon the earth are equal to one another, holds back from the circles which surround it, of which the meridian is the greatest; and the second, which divides it into two equal parts, is the horizon; and the third, which separates these, the equinoctial; and on each side of this the two tropics, the summer and the winter—the one on the north, and the other on the south. Beyond is that which is called the axis, around which are the greater and lesser Bears, and beyond them is the tropic. And the Bears, turning about themselves, and weighing upon the axis, which passes through the poles, produce the motion of the whole world, having their heads against each other’s loins, and being untouched by our horizon.

Then they say that the Zodiac touches all the circles, making its movements diagonally, and that there are in it a number of signs, which are called the twelve signs of the Zodiac, beginning with the Ram, and going on to the Fishes, which, they say, were so determined from mythical causes; saying that it was the Ram that conveyed Helle, the daughter of Athamas, and her brother Phryxos into Scythia; and that the head of the Ox is in honour of Zeus, who, in the form of a Bull, carried over Europe into Crete; and they say the circle called the Galaxy, or milky way, which reaches from the Fishes to the Ram, was poured forth for Herakles from the breasts of Hera, by the commands of Zeus. And thus, according to them, there was no natal destiny before Europe or Phryxos, and the Dioscuroi, and the other signs of the Zodiac, which were placed among the constellations, from men and beasts. But our ancestors lived without destiny. Let us endeavour now to crush falsehood, like physicians, taking its edge off, and quenching it with the healing medicine of words, here considering the truth.
