Both Pietro and his wife have legitimate complaints in this moment. Pietro is bothered to discover that his wife has been cheating, and he’s rightfully annoyed that she criticized another woman for doing the same thing she herself has done. But medieval conceptions of marriage held that husbands and wives were responsible to care for each other’s sexual needs, so Pietro’s wife is also correct to point out that he has failed to hold up his end of the bargain. Pietro acknowledges this impasse when he backs down. But his wife’s ability to get away with her affairs without punishment draws both on a cultural antipathy for Pietro’s homosexuality and on the
fabliaux tradition, where clever wives are never punished for pulling one over on husbands who deserve it for failing to meet their wives’ sexual needs.
