 Filomena's tale may originate from the early 13th century "Chronicle of Helinandus".However, the tale was a widespread one and Boccaccio could have taken it from any number of sources or even oral tradition.Federigo degli Alberighi, who loves but is not loved in return, spends all the money he has in courtship and is left with only a falcon, which, since he has nothing else to give her, he offers to his lady to eat when she visits his home; then she, learning of this, changes her mind, takes him for her husband, and makes him rich.
