In ancient Irish legend, the wife of Finn Mac Cummal and
mother of Oisin. Finn captured her in the form of a fawn while
hunting, but noticing that his hounds would not hurt her, he
gave her shelter. The next morning he found her transformed
into a beautiful woman. She told him than an enchanter had
compelled her to take the shape of a fawn, but that her original
form would be restored when she reached Dun Allen, where
she had just spent the night. Finn made her his wife and ceased
for a while from battle and hunting.
Hearing one day that the Northmens warships were in the
Bay of Dublin, he mustered his men and went to fight them. He
returned victorious, but found Saba gone. The enchanter, taking
advantage of Finns absence, had appeared to her in the
likeness of Finn with his hounds and lured her from the dun.
Away from the dun, she became a fawn again.
