Two separately published parts, octavo (vol. I, 163 x 103 mm; vol. II, 163 x 93 mm). Early 18th-century calf, decorated in similar style but not exactly matching, both with raised bands with elaborate gilt tooling in compartments, twin red morocco labels added sometime later (one since renewed), covers of vol. II bordered with a single gilt rule and board edges gilt, vol. II with French curl pattern marbled endpapers, edges sprinkled red; both bindings square and firm, joints of both volumes and two corners of vol. I skilfully repaired, a little loss of calf to edge of rear board of vol. I. Woodcut historiated and floriated initials, head- and tailpieces. Title page of vol. I with bookplate of the Lycée Louis-le-Grand, and ownership inscription “德金” (“De Jin”), probably Joseph de Guignes. Frequent annotations in French in ink, pencil, and red crayon in different hands to both volumes, title pages laid down on a later sheet, vol. I with closed tear to margin of three leaves and one margin with crude early repair (loss of initial letter on 11 lines), four small ink burns with loss of a few letters, occasional marks to contents, otherwise generally clean. An attractive set.
