Quires [1^8, 2^{12}, 3-4^{10}, 5^{12}, 6-7^{10}, 8^{12}, 9^{14}, 10-11^{10}, 12^{12}, 13^8, 14^6, 15-19^{10}, 20^8], 202 leaves, the last two blank, roman letter, 39 lines to the page, without signatures, catchwords or pagination. Two- to six-line spaces left for capitals and spaces also for Greek words, to be supplied in manuscript. Two pinholes on side. The type is Jenson's first font. Hain 15802. Proctor 4071. At the head of the first page is a large initial of the interlaced vine pattern in gold and colors, with a border of the same pattern enclosing the entire page. The remaining five books, the prefatory epistle and the supplement _De ego, mei et sui_ are introduced by initials of the same size and style. Alternate red and blue capitals at the head of chapters, paragraph-marks also in red and blue. A few of the spaces left for Greek words are filled in manuscript, but more are left vacant. When Jenson later in the same year printed Cicero's Letters, he was provided with Greek type. The blank fol. 9^a is occupied by a transcript in an early hand of the greater part of lib. i, cap. iv (_De ficu_), from a MS. the readings of which differ materially from the printed text.
