The Parliament of Fowls is a 699-line poem that takes the shape of the narrator's dream vision. The poem is one of the earliest to mention St. Valentine's Day as a special day for lovers. It also mentions an ancient festival called Paschal, which was celebrated on the Easter Sunday. In the poem, a king named Cupid lives in the Parliament of Fowls with his wife, Doane. Every morning they pass judgment on the desires of all creatures. If a desire is just, then it is granted; if not, then it is denied. Cupid is said to be immortal and heir to the throne of Venus. Doane is described as "a queen in love and dread". They have two children, Phoebus, who is described as being like his father in appearance, and Mars, who is described as being like his mother. At the end of each day's deliberations, Cupid and Doane review the desires of all creatures. If a creature has been unkind or hateful, then it is punished by being denied its wish. Dream interpretations often involve hidden meanings behind what appears on the surface. In this case, the interpretation involves understanding what the poet was alluding to when writing about various festivals and traditions.
