20 Nay, by Jove, said Theon, let this be the argument of your discourse. For I indeed stand in need of some persuasion, having only heard that when these three bodies, the earth, the moon, and the sun, are in a direct line, then eclipses happen; for that either the earth takes the sun from the moon, or the moon takes him from the earth. For the sun suffers an eclipse when the moon, and the moon when the earth, is in the midst of the three; of which the one happens in the conjunction or new moon, and the other in the opposition or when the moon is full.
