The aim of this contribution is to offer an essay that investigates the different ways in which Maximus plays in his astrological poem with the (presumed) origin of the words used by him or with their meaning. We will first see how our astrologer is able to put etymology at the service of the composition of his predictions; then how he exploits the semantic ambiguity of certain terms, not only to show off his erudition, but also to make his poem more in keeping with the dictates of astrological literature; finally, how he implicitly succeeds in establishing what is for him the correct interpretation of a word susceptible to different and conflicting readings.
