Recuyell of the Historyes of Troye or Recueil des Histoires de Troye, is a French courtly romance written by Raoul Lefevre, chaplain to Philip III, Duke of Burgundy. Translated by William Caxton, and printed by him probably with Colard Mansion and Johann Veldener in 1473 or 1474 (traditionally "ca. 1475") at Bruges, fairly soon after its writing. The work is now known mainly as the first book printed in the English language. The more precise dating is that given in the Incunabula Short-title Catalogue. A presentation copy of the first edition has a specially made engraving showing Caxton presenting the book to Margaret of York. This volume is now in the Huntington Library, San Marino, CA. This "patronage" may be more advertising than analogous to traditional medieval patronage.
