Watermark: two crossed arrows, similar to Briquet 6269-6275, especially to Briquet 6271 (attested 1462). The whole group and its variants are attested in Northeastern Italy 1448-1495. Script: Copied by one hand in Humanistica Cursiva Libraria/Currens, widely spaced. The first letter after an initial is in Capitalis. 2-line plain initials alternately in red and blue at the beginning of the subdivisions of the text. They are placed almost entirely in the margin and are missing ff. 17v, 28r and 33r. Guide letters, written in the space reserved for the initials, are equally often missing. On f. 1r the Prologue opens with a 4-line foliate initial in red, green and blue with two flowers on a gold background and floral extensions in the inner margin, in Lombard style; in the lower margin of the same page a painted double-headed imperial eagle in black, its two heads with a golden crown and on its chest an oval shield with the coat of arms or, three bends azure. Binding: Original Italian, undecorated blue-stained leather over beech boards. Sewn on three double leather thongs. Remnants of three clasps attached to the front board (one at the upper, one at the lower and one at the right-hand side); thin brass engraved catches on the rear cover, decorated with a floweret and the Gothic majuscule “S”. The parchment pastedowns are now detached from the boards. Collection of Bernard M. Rosenthal, Berkeley (MS 149). Purchased from Rosenthal on the Edwin J. Beinecke Fund. Parchment end leaves.
