Pausanias, The Description of Greece — Book VII (1918)
“ From the grave it is a journey of about thirty stades to what is called the Gaeum, a sanctuary of Earth surnamed Broad-bosomed, whose wooden image is one of the very oldest. The woman who from time to time is priestess henceforth remains chaste, and before her election must not have had intercourse with more than one man. The test applied is drinking bull's blood. Any woman who may chance not to speak the truth is immediately punished as a result of this test. If several women compete for the priesthood, lots are cast for the honor. ”
