Why Is Nur ad-Din al-Bitruji Influential?
(Suggest an Edit or Addition)According to Wikipedia, Nur ad-Din al-Bitruji was an Andalusian-Arab astronomer and a Qadi in al-Andalus. Al-Biṭrūjī was the first astronomer to present a non-Ptolemaic astronomical system as an alternative to Ptolemy's models, with the planets borne by geocentric spheres. Another original aspect of his system was that he proposed a physical cause of celestial motions. His alternative system spread through most of Europe during the 13th century.
