Fidele and Fortunio, the Two Italian Gentlemen

A couple of virginal gentlemen and a couple of virginal ladies exchange love-interests as they realize they cannot attain their initial desires. Their eventual marriages are attained with mischievous help from a pretense-captain Crack-Stone, a spying Pedant who fakes being in love to appear manly, and the scientific and psychologically-manipulating magic of enchantress Medusa.
