The Panathenaea were said to have been founded, or perhaps refounded, by Theseus, who, according to legend, united into one state the village communities of Attica. Certainly there existed an ancient yearly festival in honour of Athene, though we cannot say if it bore the name Panathenaea. This festival continued to be celebrated every year after the founding of the greater festival, and was called the Little Panathenaea.[86] The Great Panathenaea were a pentaëteris, and were held in the third year of each Olympiad in the month of Hekatombaion or about the end of July. The programme of the festival was even more varied than that of the Isthmia. The great event of the festival, the procession that bore the peplos to the temple of Athene on the Acropolis, afforded an opportunity for the display of all the forces of Athens. The competitions included, besides athletics and horse-races, musical contests, recitations, torch-races, Pyrrhic dances, a regatta, and even a competition for good looks. For most of the events the prizes consisted in jars of Attic oil. Olive-oil was the most valuable product of Attica: the olive trees were under the control of the state, and the export of olive-oil was a state monopoly. As many as 1300 amphorae of oil were distributed as prizes, the winner in the chariot-race receiving as many as 140 amphorae. As even at a later period an amphora of oil was worth 12 drachmae, it is clear that the prizes had a considerable commercial value. Some of the jars containing the oil were ornamented with scenes representing the various competitions. It is probable that only one such painted vase was given for each victory. The manufacture and painting of vases was already an important industry at Athens, and the prize vase full of oil represented, therefore, the chief natural product and the chief industry of early Attica. These prize vases must have been greatly cherished. Numbers of them have been found in Italian tombs and elsewhere, and the variety of the subjects depicted throws no little light on the events of the festival. But details must be reserved for another chapter.
