The author argues that Shakespeare's Hamlet (1600) was influenced by the death in 1596 of the playwright's 11-year-old twin son, Hamnet. Beyond the similarity between the dead child's name and the play's title, the language of the play, a supreme act of sublimation, does at times seem preoccupied with a kind of linguistic twinning. The play's variations on the theme of doubling—pairs of characters, for example, and the many instances of hendiadys, a figure of speech using two substantives to denote a single complex meaning, as well as Hamlet s play within a play—are indirect references to the dead twin, the author contends.
