The author, a French religious born in Cessoles in Picardy, from which he took his name, lived in the 13th century. In his Moralized Chess Game, he seeks to derive rules of conduct for all states from the play of the pieces (Larousse). The translator is unknown, but the translation is generally attributed to Jean de Vignay or Vigny. The Jeu des échecs moralisé ends on folio l5. It is followed by a book that is very similar to the previous one: a book on the order of chivalry. the order of chivalry, then, on page p5, the novel Mélibée et Prudence, a moral novel by Christine de Pisan which first appeared around 1480, and of which this is the second publication. The illustration consists of a large grotesque for the title and 4 woodcuts, including a very fine one on the verso of the title depicting a king and queen playing chess in a twelve-compartment frame depicting various characters, the plowman, the marshal, the spendthrift, the knight, the judge... A large woodcut (b4v) depicts Christ crucified surrounded by God and the evangelists, a woodcut taken from Vérard's Bible and repeated on folio p4v, and a smaller woodcut at the end of the Jeu des échecs moralisé depicting a female soldier and a man armed with a club, a woodcut that had been used for another publication by Vérard. Jeu des échecs moralisé depicting a female soldier and a man armed with a club, which had been used for another of Vérard's publications: le Chevalier Délibéré. Macfarlane describes another wood on folio p4v, but Fairfax Murray, in his lengthy description of our copy, indicates that he consulted the British Museum copy on which Macfarlane wrote his description, and that folio p4v is probably a facsimile. Macfarlane's error in describing the illustration on folio p4v is confirmed by Picot's entry in the Rothschild catalog, which describes a copy identical to ours. Very rare edition. The USTC lists six copies in public libraries. Light discoloration of spine and board edges. Inversion of the 3rd and 4th leaves and very skilful angular restorations to the first 20 leaves not affecting the text, only the engraving on the verso of the title having been slightly reworked in ink. A very fine copy bound in the arms of Baron Seillière with his supra-libris from the Mello library. Provenance: Baron Achille Seillière (supra-libris, I, May 5-14, 1890, no. 135) and Fairfax Murray (label, no. 629).
