The Roman History · Amm. 20.3.11

As she goes on still further, and reaches the fifth sign, she assumes a convex shape, a sort of hump appearing from each side. And when she is exactly opposite the sun, she shines with a full light, having arrived at the seventh sign; and even while she is there, having advanced but a very little further, she begins to diminish, which we call waning; and as she gets older, she resumes the same shapes that she had while increasing. But it is established by unanimous consent that she is never seen to be eclipsed except in the middle of her course.
