The case of Pallas Athena is even simpler, though it leads to a somewhat surprising result. What Apollo is to Ionia that, and more, Athena is to Athens. There are doubtless foreign elements in Athena, some Cretan and Ionian, some Northern.[52:1] But her whole appearance in history and literature tells the same story as her name. Athens is her city and she is the goddess of Athens, the Athena or Athenaia Korê. In Athens she can be simply 'Parthenos', the Maiden; elsewhere she is the 'Attic' or 'Athenian Maiden'. As Glaucopis she is identified or associated with the Owl that was the sacred bird of Athens. As Pallas she seems to be a Thunder-maiden, a sort of Keraunia or bride of Keraunos. A Palladion consists of two thunder-shields, set one above the other like a figure 8, and we can trace in art-types the development of this 8 into a human figure. It seems clear that the old Achaioi cannot have called their warrior-maiden, daughter of Zeus, by the name Athena or Athenaia. The Athenian goddess must have come in from Athenian influence, and it is strange to find how deep into the heart of the poems that influence must have reached. If we try to conjecture whose place it is that Athena has taken, it is worth remarking that her regular epithet, 'daughter of Zeus', belongs in Sanskrit to the Dawn-goddess, Eôs.[52:2] The transition might be helped by some touches of the Dawn-goddess that seem to linger about Athena in myth. The rising Sun stayed his horses while Athena was born from the head of Zeus. Also she was born amid a snowstorm of gold. And Eôs, on the other hand, is, like Athena, sometimes the daughter of the Giant Pallas.[53:1] Our three chief Olympians, then, explain themselves very easily. A body of poetry and tradition, in its origin dating from the Achaioi of the Migrations, growing for centuries in the hands of Ionian bards, and reaching its culminating form at Athens, has prominent in it the Achaian Zeus, the Ionian Apollo, the Athenian Korê--the same Korê who descended in person to restore the exiled Pisistratus to his throne.[53:2]
