Alpetragius

Person

Who is Alpetragius?

Alpetragius a.k.a. Nur ad-Din al-Bitruji was an astronomer and a Qadi from Al-Andalus. Despite his limited knowledge of Ptolemy's Almagest, al-Biṭrūjī was the first astronomer after Ptolemy to present a non-Ptolemaic astronomical system as an alternative to Ptolemy's models. Another original aspect of his system was that he proposed a physical cause of celestial motions.
