"Love's Labour's Lost" is, along with Shakespeare's "The Tempest", a play without any obvious sources. Some possible influences on "Love's Labour's Lost" can be found in the early plays of John Lyly, Robert Wilson's "The Cobbler's Prophecy" (c. 1590) and Pierre de la Primaudaye's "L'Academie française" (1577). Michael Dobson and Stanley Wells comment that it has often been conjectured that the plot derives from "a now lost account of a diplomatic visit made to Henry in 1578 by Catherine de Medici and her daughter Marguerite de Valois, Henry's estranged wife, to discuss the future of Aquitaine, but this is by no means certain."
