That, however, the whole worship of Apollo was not one of those originally instituted at Thebes, will be evident from the following observations. In the ancient legends respecting Cadmus, in which Demeter, Cora, Cadmus, and afterwards Bacchus, predominate in succession, Apollo never appears in a conspicuous character. For particular additions of the poets may be easily distinguished from the genuine popular tradition. The fable, that Cadmus, after the slaughter of the serpent, was, like Apollo, compelled to live _eight_ years in slavery,(1017) must be considered as a poetical transposition. Cadmus and Apollo had originally no points of resemblance to each other. The situation of the temple of Apollo at Thebes is a most convincing proof that his worship was totally distinct from any other. Those of the ancient national gods were built on the citadel of Cadmeia, whilst Apollo was not only not worshipped in the citadel, but even without the gates, in the temple of Ismene,(1018) which, according to Pausanias, must have been situated opposite to the temple of Hercules and the house of Amphitryon. This proximity of the hero and god, as well as all other points of union between the two at Thebes, will be employed for the purpose of establishing further conclusions, when we explain the legend of Hercules.(1019) To settle with any accuracy, from the traditions concerning Tiresias and Hercules, the time at which the Bœotian temples of Apollo were founded, seems hardly possible, since the former contain no chronological information, and the latter are entirely unconnected with the rest of the Theban mythology. A tradition respecting the establishment of the festival of the Daphnephoria places it at the time of the Æolian migration,(1020) whence it might perhaps be inferred that the Æolians introduced the worship of Apollo into Bœotia. This hypothesis would however involve us in endless perplexities; and it is most probable that its diffusion was gradually effected, soon after the settlement at Cirrha, about the time at which the worship of Apollo rose to importance at Athens.
