↑ Henry Ansgar Kelly, in Chaucer and the Cult of Saint Valentine (Leiden: Brill) 1986, accounts for these and further local Saints Valentine (Ch. 6 "The Genoese Saint Valentine and the observances of May") in arguing that Chaucer had an established tradition in mind, and (pp 79ff) linking the Valentine in question to Valentine, first bishop of Genoa, the only Saint Valentine honoured with a feast in springtime, the season indicated by Chaucer. Valentine of Genoa was treated by Jacobus of Verazze in his Chronicle of Genoa (Kelly p. 85).

1 2 Oruch, Jack B., "St. Valentine, Chaucer, and Spring in February", Speculum, 56 (1981): 534–65. Oruch's survey of the literature finds no association between Valentine and romance prior to Chaucer. He concludes that Chaucer is likely to be "the original mythmaker in this instance."
