Here's why:
* Debate Structure: The poem features a debate between two opposing figures, the Owl and the Nightingale, who represent contrasting ideals.
* Allegorical Nature: The debate is allegorical, with the owl representing austerity and the nightingale representing joy and pleasure.
* Courtly Setting: The poem is set in a courtly context, with the debate taking place in front of a king and other nobles.
* Moral and Ethical Themes: The poem explores moral and ethical questions about the nature of life, virtue, and pleasure.
While the poem is not a strict dramatic dialogue, it employs a conversational style with each figure taking turns presenting their arguments. This, combined with the courtly setting and allegorical nature, solidify its classification as a courtly debate poem.
