“It is often said that Greek temples are oriented to the east. That is true, but the matter can be better stated. In a sanctuary the altar – which almost always preexists the temple – is oriented to the east, and the temple is oriented to the altar. Both thus face east, but the altar determines the orientation of the temple. As a result, we will have aligned, facing the east, our monumental statue of Poseidon Soter, the building in which he stands, and the altar. We should imagine that on his festival day, the Posidea of Posideon 8, when the cella’s doors are opened in early morning, the light of the sun rising in the east flows in upon Poseidon, illuminating him and bringing the bronze to life in an otherwise rather dark room. Poseidon’s gaze, in turn, is directed through the open doors and falls upon the activities around his own altar. Our bronze Poseidon will observe the acts of worship directed to the real Poseidon at his altar on his festival day.”
