In Greek mythology, Metanira // (Ancient Greek: Μετάνειρα Metáneira) or Meganira was a queen of Eleusis and wife of Celeus. While Demeter was searching for her daughter, 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 Demophoon, his son by Metanira. As a gift to Celeus, because of his hospitality, Demeter planned to make Demophoon 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 and screamed at seeing her child in flames, which distracted the goddess. Some[who?] say that Demophoon, as a result, was destroyed by the flames, but in other sources he suffered no harm. In Ovid's Fasti, the baby was Triptolemus and not Demophoon, although in most other versions he was an adult by the time; some sources state that even his parentage was different. However, all versions agree that Demeter chose to teach Triptolemus the art of agriculture and, from him, the rest of Greece learned to plant and reap crops. He flew across the land on a winged chariot while Demeter and Persephone cared for him, and helped him complete his mission of educating the whole of Greece on the art of agriculture. Some mythological traditions tell that Metanira's son Abas mocked Demeter and as punishment was turned into a lizard; others, however, relate this of Ascalabus, son of Misme.
