Blanche of Lancaster - The Book of The Duchess

Geoffrey Chaucer was commissioned by Gaunt to write a poem after Blanche's death which was titled The Book of the Duchess. The poem tells the story of the poet’s dream. Wandering a wood, the poet discovers a knight clothed in black, and inquires of the knight’s sorrow. The knight, meant to represent John of Gaunt, is mourning a terrible tragedy, which mirrors Gaunt's own extended mourning for Blanche.
