Erika Cheatham, whose book on this man inspired a 1981 film, misinterpreted this man’s reference to the Danube River. Dolores Cannon’s first book was titled for her “Conversations with” this long-dead author. A poem by this man about reviving the Great King from Angoumois was likely inspired by the captivity of Francis I. One work by this man from Salon-de-Provence describes a shift from a republic to a monarchy and finally to a Golden (*) Age in a preface addressed to his son César. That work by this protagonist of The Man Who Saw Tomorrow is divided into ten centuries, mostly of one hundred multilingual quatrains each, and became extremely popular right after 9/11. For 10 points, name this French astrologer for Catherine (10[1])de’ Medici who wrote a collection of prophecies. ■END■
