Lyceum, << ly SEE uhm, >> was a school founded by the Greek philosopher Aristotle in 335 B.C. It was located outside the walls of Athens along the Ilissus River. It stood near Athens, in a grove sacred to the god Apollo Lykeios (also spelled Lyceius), for whom it was named. Students and teachers at the Lyceum pursued higher learning through lectures, discussions, and research. The Lyceum had one of the world’s first libraries and one of the first natural history museums. Aristotle and his followers and students lived at the Lyceum. Aristotle’s followers became known as the Peripatetics, probably after a covered walk (peripatos) attached to one of the Lyceum buildings.
