A tragic love story unfolds against a backdrop of divine indifference and human suffering. The poem follows Cresseid, who, after being abandoned by her lover Troilus, is struck by leprosy. Her descent into isolation and despair is marked by her rejection of Troilus and her eventual death, serving as a stark meditation on fate, love, and the consequences of pride.

Robert Henryson's 'Testament of Cresseid' is widely regarded as a significant work of late medieval Scottish poetry, often praised for its powerful continuation and darker reinterpretation of Chaucer's 'Troilus and Criseyde'. Critics frequently highlight its unflinching portrayal of Cresseid's suffering and its complex exploration of themes such as fate, divine justice, and the harsh realities of love and social ostracism. The poem's stark realism and emotional depth have cemented its place as a canonical text, offering a compelling counterpoint to more romanticized treatments of the same story. The inclusion of the seven fables further showcases Henryson's skill in moral allegory and narrative.
