Ascalabus son of Misme (also known as Abas son of Metaneira) was changed by Demeter into a lizard.
While searching for her daughter Persephone, Demeter came to the home of Misme. Being a good hostess, Misme offered her a drink, which Demeter, thirsty from her long search, gladly accepted.
It was all going well until Misme's son Ascalabus mocked the goddess for drinking so much so quickly and then ordered for a cask to be brought up for her. In response to his rudeness, Demeter turned the boy into a lizard. As one does.
