Giuseppe Vasi. Delle Magnificenze Di Roman Antica E Moderna Libro Primo [-Libro Decimo]... In Roma: Nella Stamperia del Characas Presso S. Maco Al Corso [and others], 1747 [circa 1790] - 1761. Ten books in two folio volumes, bound horizontally (approximately 15.75 x 11.5 inches, few smaller leaves). LXXII, [2, index]; LII, [1, index]; XLVIII, (XLIX-XLII ) index; L, (LI-LII, index); XLVII, (XLVIII, index); LII, (LIII-LIV, index), LXXII, (LXXIII-LXXV, index); XLVI, (XLVII-XLVIII, index); L, (LI-LII, index); XLVI, (XLVII-LII, index). 202 engraved plates, including etched frontispiece in first book and six extra unnumbered plates.

Book I is a second edition (although the title page is dated 1747), without the first edition's 'Sonnetto di Giuseppe Vasi' at the end and with the later half-title. Pagination matches RIBA-BAL second edition of the 1790s. The paginations of Books II - X match first editions of both RIBA-BAL and Millard.

Bound in modern half calf over cloth covered boards, five raised spine bands with gilt lettered leather title labels in compartments. Bindings rubbed at extremities, spines sunned and soiled. Previous owner's ink name on title page of Book I.

Few pages with paper laid down around margins, including title pages of Book III, VII, IX, and last leaf of book X, not affecting texts. First index page in Book II and "Prefazione" leaf in Book VII, repaired and backed with paper. Book V pages XIX/XX side margins refreshed. Plate 134 in Book VII with a small paper repair and ink spot in lower margin. Plate 167 with a small hole in the lower right corner of the image area. Few small wormholes and tracks grouped in the margins of both Book IX and Book X, alternating from upper to lower corners, not affecting text or images. Plates with occasional small holes at edges, not affecting image areas, and light image offset to adjacent pages. Few minor dampstains and occasional foxing. Overall a remarkably clean and very attractive set of Vasi's magnum opus.
