for they, being, according to him, like stones and heavy, shine by the refraction of the upper air round about them, and are carried along forcibly by the violence of the circular motion by which they were originally withheld from falling, when cold and heavy bodies were first separated from the general universe. But there is a more probable opinion than this maintained by some, who say that falling stars are no effluxes, nor discharges of ethereal fire, extinguished almost at the instant of its igniting by the lower air; neither are they the sudden combustion and blazing up of a quantity of the lower air let loose in great abundance into the upper region; but the heavenly bodies, by a relaxation of the force of their circular movement, are carried by an irregular course, not in general into the inhabited part of the earth, but for the most part into the wide sea; which is the cause of their not being observed. Daimachus, in his treatise on Religion, supports the view of Anaxagoras. He says, that before this stone fell, for seventy-five days continually, there was seen in the heavens a vast fiery body, as if it had been a flaming cloud, not resting, but carried about with several intricate and broken movements, so that the flaming pieces, which were broken off by this commotion and running about, were carried in all directions, shining as falling stars do. But when it afterwards came down to the ground in this district, and the people of the place recovering from their fear and astonishment came together, there was no fire to be seen, neither any sign of it; there was only a stone lying, big indeed, but which bore no proportion, to speak of, to that fiery compass. It is manifest that Daimachus needs to have indulgent hearers; but if what he says be true, he altogether proves those to be wrong who say that a rock broken oft' from the top of some mountain, by winds and tempests, and caught and whirled about like a top,
