Thomas Aquinas’ astronomical theories were influenced by ancient astronomers like Aristotle and Ptolemy. His geocentric model, with the Earth at the center of the universe and spheres carrying the planets and stars, was based on the prevailing understanding of his time. Aquinas believed that the universe was created by God and had a purpose, with the motion of the heavens being evidence of God’s design. His theories reflect the intellectual context of medieval scholasticism, with the influence of Albertus Magnus and Averroes. Aquinas’ ideas provided a framework for understanding the natural world within a theological context.
