I can only suggest conjecturally either that the date of the festival had been for some reason shifted in the time of Berosus, or that two different festivals of the same type may have been held at different seasons of the year, one in spring and one in summer, perhaps by two distinct but kindred tribes, who retained their separate religious rites after they had coalesced in the Babylonian empire. Both conjectures might be supported by analogies. On the one hand, for example, in the Jewish calendar New Year’s Day was shifted under Babylonian influence from autumn to spring,(818) and in a later part of this work we shall see that the Chinese festival of new fire, at first celebrated in spring, was afterwards shifted to the summer solstice, only however to be brought back at a later time to its original date. On the other hand, the popular festivals of our European peasantry afford many examples of rites which appear to be similar in character, though they fall at different times of the year; such, for instance, are the ceremonies concerned with vegetation on May Day, Whitsuntide, and Midsummer Day,(819) and the fire festivals which are distributed at still wider intervals throughout the months.(820) Similarly in ancient Italy the agricultural festival of the Ambarvalia was celebrated by Italian farmers at different dates in different places.(821) These cases may warn us against the danger of hastily inferring an essential difference between Zakmuk and Sacaea on the ground of a real or apparent difference in their dates.
