Anaxagoras (/ˌænækˈsæɡərəs/; Ancient Greek: Ἀναξαγόρας, Anaxagoras, "lord of the assembly"; c. 510 – 428 BC) was a Pre-Socratic Greek philosopher. Born in Clazomenae in Asia Minor, Anaxagoras was the first philosopher to bring philosophy from Ionia to Athens. He attempted to give a scientific account of eclipses, meteors, rainbows, and the sun, which he described as a fiery mass larger than the Peloponnese.
