_X_ in Plate I represents part of the Stadium, which is about six hundred feet long. Here are remains of at least fifteen rows of marble seats. Probably foot races took place here as well as other forms of athletic exercise. All the maps of the Hieron represent the eastern end of the Stadium as semicircular, but so far as one can judge, the latest excavations indicate that it was square, and therefore I have so represented it. [Illustration: PLATE XVIII—East end of Stadium] Assuming that the fifteen rows of seats extended from end to end on each side, and allowing a foot and a half for each person, the Stadium would seat twelve thousand spectators on its two sides, without computing the seats at the ends. Plate XVIII represents the excavation at the end adjacent to the Hieron. _Y_ in Plate I (shown also in Plate XVIII) is either the starting place or the goal. _Z_ is a subterranean passage probably communicating with the precinct. An inscription (found in 1896) mentioned by Mr. Frazer, shows that a hippodrome also existed at the Hieron. On Mount Kynortion, some distance south of the great theatre, stood the temple of the Maleatean Apollo. The remains are so fragmentary that it is difficult to devise a conjectural restoration. II. The Asklepieion at Athens Before saying anything about the ritual and the treatment of the sick at the Hieron, it will be well to turn to the Asklepieion at Athens, and examine briefly the structural arrangements there. Situated on the south side of the Acropolis, at an elevation of perhaps eighty feet above the plain, adjoining on the east the theatre of Dionysus, the locality was probably as healthy as any the immediate neighbourhood of Athens could supply. The heat no doubt was great in summer, but we may conclude that a grove of large trees afforded grateful shade to the sick.
