English 18th-century antiquarians Alban Butler and Francis Douce, noting the obscurity of Saint Valentine's identity, suggested that Saint Valentine's Day was created as an attempt to supersede the pagan holiday of Lupercalia (mid-February in Rome). This idea has lately been dismissed by academics and researchers, such as Professor Jack B. Oruch of the University of Kansas, Henry Ansgar Kelly of the University of California, Los Angeles and Associate Professor Michael Matthew Kaylor of the Masaryk University. Many of the current legends that characterize Saint Valentine were invented in the 14th century in England, notably by Geoffrey Chaucer and his circle, when the feast day of February 14 first became associated with romantic love.
