The pre-Socratic Greek philosopher Anaxagoras (500—428 BCE) was the first to bring philosophy to Athens, which would later become the philosophic centre of the Western world.
Anaxagoras attempted to provide scientific descriptions of celestial phenomenon. For instance, he described the sun as a large mass of fire, larger than the Peloponnese. (It”s worth noting: he was correct, although perhaps imprecise.) His scientific accounts, however, were not welcome at the time, and he was forced to flee Athens for Lampsacus to avoid persecution.
