or Aldabelle (in Orlando Furioso). Sister of
Oliviero and Brandimarte, daughter of Monodantes, and wife of Orlando.
A marchioness of Florence, who gave entertainment to the magnates
of the city. She was very handsome, heartless, and arrogant. When Fazio
became rich with Bartoldo's money, Aldabella inveigled him from his
wife, and his wife, out of jealousy, accused her husband of being privy
to Bartoldo's death. Fazio being condemned for murder and robbery, his
wife Bianca accused Aldabella of inveigling him, and the marchioness
was condemned by the Duke of Florence to spend the rest of her life in
a nunnery. —Dean Milman: Fazio.
