Sorry to have spoiled the fun. (Much of mathematics in the ancient world was linked to astrology, hence the confusion.) Let me make up for it with a High Mediaeval (1360s?) quotation:

"A prince […] must not know the demonstrations of Ptolemy, nor strive to understand the planets, nor study astrolabes or such things, even if the abstention is painful to him […] for it is certain that a prince who gave too much pains to these subjects would not be considered wise but fanciful."

(Nicolas Oresme, Livre de divinations)
