Lot Essay
Il Puttino, dedicated to Pietro Giordano Ursino, contains an account of the career of Leonardo, extracts from Cesssolis, 13 chapters on gambitti, 7 on giochi piani (games that were not gambits), and 13 on problems. The Trattato, dedicated to Mario di Bologna, "mio padrone", is described by Murray as "practically a reprint of the games and problems of the 1604 edition" though the third book is devoted "to a bitter attack on Carrera" whose Gioco degli Scacchi (1617) had made an isolated criticism of a move in a Queen's Gambit in the 1604 edition of the Trattato (cf. Murray, pp. 825-27)
