(Lacking 2 index lvs., supplied in manuscript, one leaf torn with loss, browned.)Contemporary Roman olive morocco gilt BY GREGORIO ANDREOLI FOR CARDINAL GIULIO ROSPIGLIOSI (LATER POPE CLEMENT IX), tooled to a post-fanfare design incorporating azured lozenges (derived from the Rospigliosi arms) and fan corner ornaments, shaped compartments with a semé of tiny stars or flames, spine with central flower tool and arabesques, gilt edges (slight wear at extremities, spine lightly faded and with minor repair at head, a few wormholes at tail, and slight wear in top compartment).

Previously named only for its main patron, the Rospigliosi bindery was identified by José Ruysschaert as the bindery of Gregorio and Giovanni Andreoli. It was one of the most active and celebrated Roman shops in the 17th century, which counted among its patrons not only Giulio Rospigliosi, for whom the present binding was commissioned, but several other popes, noble families, such as the Medici and Borghese, and royalty, such as Giulio's close friend, Queen Christina of Sweden. An identically-bound copy of another part of this work was formerly owned by Major J.R. Abbey (see sale, Sotheby's, 22 June 1965, lot 321, described as black morocco); it was reproduced in Hobson, French and Italian, no. 75, and listed as no. 40 in Foot's list of the work of this bindery in Davis Gift, I, pp.326-336. Even before acceding to the papal throne, Giulio Rospigliosi was a renowned patron of the arts and author of operatic libretti. His library remained largely intact until 1933, when 60 books were offered for sale by the Roman bookshop, Il Bibliofilio (cf. Hobson, op.cit.).
