Gaia received real cult in ancient Greece, genuinely worshipped rather than left as pure myth, though never on the scale of the major Olympians. Pausanias, writing his second century CE survey of Greek sanctuaries, records that one of the oldest cult sites at Olympia, predating the great temple of Zeus, was the Gaion, an altar and precinct shared with her daughter Themis and tied to an oracle that functioned there before Zeus's own cult was established on the site. In Athens, Pausanias also records a statue of Gaia standing in the Areopagus court beside those of Hermes and Plouton, where she was invoked as witness and avenger of wrongdoing, an extension of the older Greek practice of swearing solemn oaths by Gaia and Ouranos together. Her altars stood inside sanctuaries of Demeter in several regions besides, her identity as earth goddess folding naturally into Demeter's own grain and fertility cult rather than requiring a separate temple network of her own, and sacrifice to her used black victims, the color Greek ritual reserved for chthonic, underworld facing deities rather than the sky gods. What Gaia never received was a major civic cult to rival Demeter's Eleusinian Mysteries or any Olympian's state temple: her worship survived chiefly as an older layer folded into younger, more specific cults, modest and secondary next to her narrative centrality to the cosmos itself.
