FREDERICK II, Emperor of Germany. Reliqua librorum … de arte venandi cum avibus. Leipzig: I.G. Muller, 1788-1789. 2 volumes in one, 4° (258 x 200mm). 6 engraved plates, one folding, all by Grünler after Schneider. (Both titles lightly browned, text leaves lightly and evenly browned throughout, stronger on last two leaves of index, plates lightly spotted.) 19th-century morocco-backed boards, spine lettered and decorated in gilt. Provenance: Grandjean d'Alteville (faded stamp on both titles and one leaf of text). Second edition of this early work attributed to Frederick II of Germany (1194-1250), first published in 1596. Schwerdt calls it a 'classic book on hawking, held to be the best and most comprehensive treatise, which, with original Italian and Latin manuscripts, has been the subject of study and research by many writers'. Although Schwerdt mentions a reissue published in 1756, Ceresoli and Nissen both describe the 1788-89 edition as the second. Ceresoli 243; Harting 308: 'The excellent treatise composed in Latin … was the first which appeared in the West, and is still one of the best which exists'; cf. Nissen ZBI 333; Schwerdt I, 187.
