(Βαυβώ or Βαβω), a mythical woman of Eleusis, whom Hesychius calls the nurse of Demeter; but the common story runs thus :--on her wanderings in search of her daughter, Demeter came to Baubo, who received her hospitably, and offered her something to drink; but when the goddess, being too much under the influence of grief, refused to drink, Baubo made such a strange gesture, that the goddess smiled and accepted the draught. (Clem. Alex. Cohort. p. 17.) In the fragment of the Orphic hymn, which Clemens Alex. adds to this account, it is further related, that a boy of the name of Iacchus made an indecent gesture at the grief of Demeter. Arnobius (Adv. Gent. v. p. 175) repeats the story of Baubo from Clemens, but without mentioning the boy Iacchus, who is otherwise unknown, and, if meant for Dionysus, is out of place here. The different stories concerning the reception of Demeter at Eleusis seem all to be inventions of later times, coined for the purpose of giving a mythical origin to the jokes in which the women used to indulge at the festival of this goddess.
