Willobie His Avisa is an ironic book of opposites.
We are told that chaste Avisa is the opposite of unchaste Penelope but we discover that Avisa is THE SAME as unchaste Penelope.
We are told that Avisa is poor but we discover that she is RICH , PENELOPE RICH to be exact.
Avisa /Penelope constantly reverses classical legends, in leaving the nobleman she threatens to plunge a knife in his heart this is the opposite to Shakespeare's Lucreece who plunges a knife into her own heart rather than be an unchaste woman.
It is she and not Ulysses who is the destructive Eagle.
Avisa often inverts Biblical quotes She quotes Saint Paul who instructs not to share food with an immoral person then she promptly shares a drink with the Caveliero ,the most immoral suitor of them all.
The book ends with the quote ever or never again this is an allusion to opposites. This tells us that the book from start to finish is about opposites.This tells us what the author is really implying about Avisa . Avisa isn't really loyal to her husband and doesn't love him. She is not constant She is not really rejecting the suitors. She is not chaste .
