Archelaus of Athens (l. c. 5th century BCE) was a Pre-Socratic philosopher in ancient Greece who claimed the first cause of existence was the opposition of cold and heat which caused the separation of the universal essence to produce a plurality of living things. He is considered the last Pre-Socratic philosopher as he is claimed to have taught Socrates.
