Doso

In Greek mythology, Doso was an alias of Demeter.

While Demeter was searching for her daughter (who had been kidnapped by Hades), having taken the form of an old woman called Doso, she received a hospitable welcome from Celeus, the King of Eleusis in Attica. He asked her to nurse Demophon and Triptolemus, his sons by Metanira. As a gift to Celeus, because of his hospitality, Demeter planned to make Demophon immortal by burning his mortal spirit away in the family hearth every night. She was unable to complete the ritual because Metanira walked in on her one night. Instead, Demeter chose to teach Triptolemus the art of agriculture and, from him, the rest of Greece learned the plant and reap crops.
