In two parts: I. Parchment, f. 1; 463 × 682 mm. plus an extension at bottom right of 175 × 215 (415 × 632) mm. Border is highly colored with acanthus leaves and figures. Black ink for nomenclature in a minuscule script with area names in display script; land masses outlined in green with islands painted red, blue, gold, or silver; 12 elaborate compass roses with usual 32 rhumb line network in black, red, and green ink for the principal directions; 4 numbered latitude scales (with portions offset), no longitude; small numbered scale of distance in gold; colorfully decorated with banners, coats of arms, urns, etc. II. Parchment, f. i (modern parchment) + 20 + i (modern parchment); 220 × 146 (158 × 103) mm. 16(-1) 2-34 48(-1); in quire 1 the first leaf was the oversized chart, now removed. Last quire has faint numbers at bottom on recto and verso which correlate with the numbers at the top of the tables for the 4 year solar declination cycles. Ruled borders in black ink. Modern pencilled numbering. Black and red ink for nomenclature in a minuscule script on charts (ff. 5v-7) with area names in display script; no rhumb lines, latitude, longitude, or distance markings; black, red, and blue ink for tables; small illustrations in table on f. 7v. Bound, s. XIX, in red velvet with ties; world chart has been removed from volume, flattened and stored in separate modern brown cloth case. Probably made in Brittany (Le Conquet, near Brest?) by Guillaume Brouscon. World chart bears initials “G. B.” and year “1543” in the border. Although Harrisse in Découverte (see below) and others have ascribed the work to Giovanni Benedetto, it is now attributed to Guillaume Brouscon because of the Breton saints in the calendars, the Breton port nomenclature, and the marked similarity to Brouscon manuscripts in other libraries, such as London, Brit. Lib. Add. 22721 signed and dated 1543 and Cambridge, Magdalene College, Pepys 1 which has been published in facsimile as Sir Francis Drake’s Nautical Almanack 1546 (Cambridge 1980) with explanation by H. Derek Howse. On the extension of the world map originally bound into the front of the volume are the arms of Artus de Cossé, Maréchal de France (1512-82), the first owner (?); his name is pencilled below the coat of arms, and arms are described on flyleaf of the volume by a later owner. Given by a Dr. Moore (of Paris) ca. 1850 to Joseph Brooks Yates (1780-1855). Bequeathed by him to Henry Yates Thompson (1838-1928), whose bookplate is on front flyleaf marked “95, Inherited J. B. Y. 1856” (Cat. II, 1902, 2d series, n. 95). His sale, Sotheby’s, 3 June 1919, pt. I, n. 27 with reproductions of the coat of arms and portion of the world chart to G. D. Smith from whom it was acquired by Henry E. Huntington. Bibliography: Harrisse, Découverte, 223-24 with reproduction of portion of North American coast line on frontispiece. H. Y.
