A recusatio is a poem (or part thereof) in which the poet says he is supposedly unable or disinclined to write the type of poem which he originally intended to, and instead writes in a different style.
The recusatio is something of a topos in ancient and Renaissance literature.[1] Its use has often been interpreted as a persona deliberately adopted by the poet, allowing him to assert himself in the guise of ironic self-deprecation or feigned humility.[2]
