The programme is divided into open events (ἐκ πάντων) and local events (ἐκ τῶν πολιτῶν). The open events are the six events of the Olympic programme. These take place in the hippodrome. The local events take place partly in the hippodrome, partly in the city in the neighbourhood of the Eleusinium, where perhaps the races ended. Some of the events are ceremonial in character, others military. Of the latter some are confined to soldiers. There are three riding races for officers (ἐκ τῶν φυλάρχων), a straight race (ἄκαμπτον) and a diaulos, and a diaulos ἐν ὅπλοις, _i.e._ in which the riders wear full armour. Similarly there are three races for cavalry (ἐκ τῶν ἱππέων). In all these races the riders rode their war-horses (ἵππῳ πολεμιστῇ). There are twelve events open to all citizens—five held at the Eleusinium, seven in the hippodrome. These include no less than eleven chariot-races, three ceremonial,—the apobates race, and two races in processional chariots,—four races in racing chariots over the straight and the double course, and four races in war-chariots (ἅρματι πολεμιστηρίῳ, συνωρίδι πολεμιστηρίᾳ) by which perhaps we may understand that, as in Homeric days, there were two men in each chariot, the driver and the soldier. There was only one horse-race, a race ἵππῳ πολυδρόμῳ, by which word I am inclined to understand a war-horse, though it may be merely a variant for fully grown. The “apobates”[407] was a ceremonial race peculiar to Athens and Boeotia, and recalled, according to tradition, the invention of the chariot by Erechtheus. At the founding of the Panathenaea he had himself appeared as charioteer, having with him in his chariot a companion armed with small round shield and triple-crested helmet, as represented in the frieze of the Parthenon. The event undoubtedly preserves the tradition of Homeric warfare when the chieftain was driven to the scene of action and dismounted to fight, remounting again for pursuit or flight. There is some doubt as to the manner of the race. According to one statement[408] the apobates mounted the chariot in full course, by placing a foot on the wheel, and again dismounted, the performance being repeated apparently at fixed intervals.
