Andreas Eudaemon-Joannis

Andreas Eudaemon-Joannis (1566 to 1625) was a Greek Jesuit, natural philosopher and controversialist, sometimes known as Cydonius. He entered the Society of Jesus in Italy in 1581 and was at the Collegio Romano, where in 1597 and 1598 he lectured on Aristotle's Physics and other works and wrote on projectile motion. From 1601 he was at Padua, where he discussed the ship's mast experiment with Galileo Galilei. He later served as theologian and adviser to Cardinal Francesco Barberini and in 1622 became rector of the Greek College in Rome. Much of his writing defended Cardinal Robert Bellarmine and the Catholic position against English attacks over the oath of allegiance of James I, a pamphlet war that drew in Isaac Casaubon and John Prideaux. He died in Rome on 24 December 1625.
