The Disagreement of Ptolemaic Astrology

Cardano wanted to make astrological practice authentically Ptolemaic. He called Abu Mashaar, Al-Kabisi and other scientists of the Islamic world "a crowd of idiots" Agostino Nifo took a similar view; he said they had distorted Ptolemy's original teachings. Another disputed point was planetary conjunctions, such as the one invoked in that prediction about the flood.
