The Library of a 'Humanist Prince' Federico da Montefeltro and His Manuscripts [by M.G. Critelli]

Stefano Gradi's inventory

After the Latin manuscripts arrived to the Vatican in 1657, they were cataloged by the erudite Dalmatian Stefano Gradi (Stjepan Gradič, 1613-1683). After Holste’s death, he was appointed second custodian (1661-1682). They were rearranged by subject and author, numbered and cataloged for the first time probably in the years 1661-1667 and a second time before 1671 (see Guida ai fondi, p. 541; Peruzzi, «Lectissima politissimaque volumina», pp. 380-381, 383).

The Inventarium scriptorum codicum bibliothecae Urbinatis D. Stephani Gradii confectum is currently identified with the shelfmark Urb. lat. 1388 and is comprised of 1,361 inventorial sheets which, sometime after the elaboration, were glued onto the folios of a printed volume with theological contents. To each manuscript there exists a description of the works that it contains, along with an indication of the folio of the incipit for each individual text (for Urb. lat. 1, for example, the description of the texts occupies seven pages of the inventory) as well as the main pieces of information for the external description: dating, material, binding, size and total number of the chartae scriptae; it is likely that on the occasion of this inventory the codices were indeed numbered (in the previous inventories there are no indications regarding the foliation).

By 1671 Gradi had arranged for a second ordering: on the same inventorial sheets/cards, the first shelfmark was systematically crossed out and replaced by a second numbering according to which the sheets were progressively glued onto the volume. This second collocation ordering complements the codices from Urbino and those from the Roveresche collection conserved in Urbania.

In 1671, on the basis of this second ordering (which thus must have been done sometime previous to this date) the scriptor latinus (1667-1713) Giacomo Vincenzo Marchesi (d. 1713) created the alphabetical index of the authors and works of the Urbinati latini manuscripts, passed down on ff. 1r-139v of Urb. lat. 1771. This constituted a polished and therefore “official” copy.

The shelfmark that was assigned to the manuscripts in this last reordering can be found written in gold on the spine of the manuscripts, and accompanied by the initials “VRB”, as well as written in pen on the first sheets of the manuscript, generally on the incipit page, in the upper internal corner (see Urb. lat. 9, f. 1r; 52, f. 1v; 74, f. 1r; 136, f. Ir; 250, f. 2r; 264, f. 2r; 281, f. 1r; 651, f. 2r; 1324, f. 2r). Sometimes it is also found in the lower internal corner (Urb. lat. 1221, f. 2r) or on the flyleaves (see Urb. lat. 324, f. [IV]r and Urb. lat. 328, f. [I]r). Each impression of this shelfmark constitutes a sign of the fact that at that time the arrangement was considered definitive.
