Ibn Tufayl, born in Guadix (Granada) in the century XII, is almost certainly the scientist from Granada who has most influenced Western thought. He was a faithful follower of Avempace and was particularly interested in the intellectual ecstasy of Avicenna and the Sufism of Algacel. Ibn Tufayl was also a doctor, first in Granada and then in other cities of the old Al-Andalus. Later he resigned as royal physician in favor of his disciple, Averroes. Pioneer of the anti-Ptolemaic revolution rooted in the teachings of Aristotle, Ibn Tufayl denied epicycles and eccentrics due to their physical impossibility, a very important detail given that the current models at that time were based only on Geometry. His work ““ The Self-taught Philosopher ”has been preserved and had a great influence on European literature.
