The Celtic scholar Nora Chadwick notes that in Irish mythology the prophetess Fedelm tells Queen Medb that she has been in the land of Alba learning the art of the Filidect. Medb asks if she has learned Imbas Forosnai, and when told yes, Medb asks Fedelm if she will look into her future to see how she will prosper. She then chants her prophecy in the form of a poem. According to many scholars, the name "Fedelm" itself means "prophetess" and is said to derive from the proto-Celtic stem wēd- / wid- "to know, to see".
