Ex ore astrologi

This is from the enormous anthology of distich poetry assembled by Barthold Nihus, Epigrammata Disticha, published in 1642; this is an anonymous poem making fun of astrologers and other soothsayers such as Nostradamus.

Ex ore astrologi
Nostra damus, cum falsa damus: nam fallere nostrum est;
Et cum nostra damus, non nisi falsa damus.
