combined with difference, that makes the study of Greek sculpture fascinating in itself, and fruitful for the understanding of the Greek religion. It lies beyond the scope of this chapter to consider how the Greek intelligence was first employed upon the articulation of its mythology, and next upon its criticism. The tradition of a Titanomachy, or contest between nature-powers and deities of reason, marks the first step in the former process. The cosmogonical forces personified in the Titans gave place to the presiding deities of political life and organized society, in whom the human reason recognized itself as superior to mere nature. Olympus was reserved for gods of intellectual order, and thus the Greeks worshipped what was best and noblest in themselves. At the same time the cosmogonical divinities were not excluded from the Greek Pantheon, and so there grew up a kind of hierarchy of greater and lesser deities. Oceanus, Poseidon, Proteus, the Tritons and the Nereids, Amphitrite and Thetis, for example, are all powers of the sea. They are the sea conceived under different aspects, its divine personality being multitudinously divided and delicately characterized in each case to accord with the changes in the element. The same kind of articulation is observable in the worship of deities under several attributes. Aphrodite Ourania and Aphrodite Pandemos are one as well as two. Eros and Himeros and Pothos are not so much three separate loves, as love regarded from three different points of view. Here the hierarchy is psychological, and represents an advance made in reflection upon moral qualities; whereas in the former case it was based on the observation of external nature. To this inquiry, again, belongs the question of imported myths and foreign cults. The worship of Corinthian Aphrodite, for example, was originally Asiatic. Yet, on entering Greek thought, Mylitta ceased to be Oriental and assumed Hellenic form and character. Sensuality was recognized as pertaining to the goddess whose domain included love and beauty and the natural desires.
