Gymnasium (ancient Greece)
The gymnasium in ancient Greece functioned as a training facility for competitors in public games. It was also a place for socializing and engaging in intellectual pursuits. The name comes from the Ancient Greek term gymnós meaning "naked". Athletes competed nude, a practice said to encourage aesthetic appreciation of the male body and a tribute to the gods. Gymnasia and palestrae were under the protection and patronage of Heracles, Hermes and, in Athens, Theseus.
