The Rape of Lucrece (1594) is a narrative poem by William Shakespeare about the legendary Lucretia.
 In his previous narrative poem, "Venus and Adonis" (1593), Shakespeare had included a dedicatory letter to his patron, the Earl of Southampton, in which he promised to write a "graver work".
 Accordingly, "The Rape of Lucrece" has a serious tone throughout.
