14995 Archytas           Discovered 1997 Nov. 5 by P. G. Comba at Prescott.
Archytas (ca. 428-365 B.C.) was a philosopher and mathematician of the Pythagorean school. He is believed to have established the quadrivium (arithmetic, geometry, music, astronomy), which together with the trivium (grammar, rhetoric, dialectics) was the foundation of classical education.
