Thomas Usk (died 4 March 1388) was appointed the under-sheriff of London by Richard II in 1387.
Born in London, he is the author of The Testament of Love, which was once thought to be by Geoffrey Chaucer.
[1] When Gloucester's party gained power through the Merciless Parliament Usk was prosecuted in 1388 and sentenced to be drawn, hanged, and beheaded, with his head put up over Newgate.
[1] The Testament of Love is an allegorical prose work written in prison to seek aid.
Walter Skeat found that the initial letters of the sections formed an acrostic saying, "MARGARET OF VIRTU HAVE MERCI ON TSKNVI."
