[Dicineus] urged them to contemplate the twelve signs and the courses of the planets passing through them, and the whole of astronomy. He told them how the disc of the moon gains increase or suffers loss, and showed them how much the fiery globe of the sun exceeds in size our earthly planet. He explained the names of the three hundred and forty-six stars and told through what signs in the arching vault of the heavens they glide swiftly from their rising to their setting.

Think, I pray you, what pleasure it was for these brave men, when for a little space they had leisure from warfare, to be instructed in the teachings of philosophy! You might have seen one scanning the position of the heavens and another investigating the nature of plants and bushes. Here stood one who studied the waxing and waning of the moon, while still another regarded the labors of the sun and observed how those bodies which were hastening to go toward the east are whirled around and borne back to the west by the rotation of the heavens. When they had learned the reason, they were at rest.
