Gymnastic exercises were conducted partly in the palæstras, or wrestling schools, partly on the race-courses, both of which were under the direction of professional trainers (παιδοτρίβαι). In early times, the palæstra and race-course were simply an open space covered with sand and probably connected with the school (διδασκαλεῖον), thus corresponding to our playground. Later, this space was partly covered over and furnished with dressing-rooms, a bath, seats for spectators, an altar for sacrifices, statues, etc. Of the five gymnastic exercises in which boys were trained, all except wrestling seem to have been conducted on the race-course, so that the palæstra was reserved for what its name implied. It is by no means certain that every palæstra had a race-course connected with it, at least in the time of which we are speaking, and possibly in many cases the boys took part of their exercises in the public race-course running from the agora to beyond the walls. Just as the schoolroom was decorated with images of Apollo and the Muses, so the palæstra was decorated with images of Hermes, Heracles, and Eros, symbolizing, respectively, adroitness, human strength, and youthful friendship. The special patron of the palæstra was Hermes, and the gymnastic exhibition took the form of a festival to him, the Hermæa, at which a sacrifice was offered and the boys were allowed the use of the building to play games in, the victors wearing crowns. It would be impossible, in a work of this compass, to enter into a minute description of all the exercises of the Athenian palæstra. We must be content with a general statement, which may be prefaced with the remark that these exercises were at first light, increasing gradually in rigor and difficulty as the strength and skill of the growing child permitted. The chief gymnastic exercises were five, named in this order in a famous line of Simonides: (1) leaping, (2) running, (3) discus-throwing, (4) javelin-casting, (5) wrestling (πάλη), which last gave the name to the palæstra. We shall not strictly follow this order, but begin with
