How did ancient Greeks explain apparent motion of the sun?

Ancient Greeks explained the apparent motion of the sun primarily through the geocentric model, which posited that the Earth was at the center of the universe. They believed that the sun moved in a circular path around the Earth, rising in the east and setting in the west due to this orbit. Philosophers like Aristotle and later Ptolemy contributed to this understanding, framing it within a broader cosmological system that included celestial spheres. Additionally, they observed the sun's daily and seasonal movements, which they linked to the changing positions of the stars and constellations.
