The experience deeply shook Pico. He reconciled with Savonarola, who remained a very close friend. It was at Pico's persuasion that Lorenzo invited Savonarola to Florence. But Pico never renounced his syncretist convictions. He settled in a villa near Fiesole prepared for him by Lorenzo, where he wrote and published the "Heptaplus id est de Dei creatoris opere" (1489) and "De Ente et Uno" ("Of Being and Unity", 1491). It was here that he also wrote his other most celebrated work, the "Disputationes adversus astrologiam divinicatrium" ("Treatise Against Predictive Astrology"), which was not published until after his death. In it, Pico acidly condemned the deterministic practices of the astrologers of his day.
