While the image of Monna Lisetta’s bigheadedness is certainly an indictment of women for their vanity (compare this, for example, to Filostrato’s warnings against vanity at the beginning of II, 7), it’s also simply a funny image that works to dispel the trauma of the preceding story. When Friar Alberto stuffs himself with fine food, he both prepares for his upcoming sexual adventures (since he will need his strength) and he acts out another sin for which the medieval clergy were often criticized: gluttony, or excessive indulgence in food and alcohol. When Lisetta falls on her knees before the “angel” and Alberto blesses her, they assume the positions of the Blessed Virgin Mary and the Archangel Gabriel in the Annunciation, both recalling the language Alberto used in relating his dream, and emphasizing Lisetta’s vanity, since she seems to believe herself to be on Mary’s level. The adoration and blessing and the description of the sex are also meant to be funny.
