Carolingian minuscule.

Later gothic initials (14th-15th c.?) in red have been added at the beginning of each Latin verse (odd pages). Greek verses without initials.

Others scripts:

.- Gothic (13th c. ?): marginal and interlinear notes.

.- (When reused) a 17th-18th c. hand wrote on pp. 339 and 344, and 341-342 the book titles on the spines of their hostvolumes.

.- p. 336-337: Three strips vertically cut and sewn. The triangle-shaped cuts on their edges as well as the folding marks show exactly how two of them were used to bind a book. Parasite holes are seen in there. The part at exposure has been different in every one of the first two upright strips of this fragment. The outer is the darkest one on page 336. On the contrary, the middle strip is darkest one on p. 337.  

.- p. 338-339 and 344-345. marks of three folds in pp. 338-339: the vertical one 40mm away from the inner edge of the folio, and others are across, 20mm away from the top margin and ca. 4 mm from the bottom one. A hole is currently found where the upper and lower folds crisscross (the cover corner which hid on the top). The upper fold and the hole affect the text of the marginal note. These folds let us notice that these two pages, together with pp. 344-345 made up a book cover (pp. 338 and 345 were the inner part, and 339-344 the outer). On the bottom of pp. 344 and 339 (upside-down) part of the title written on the original spine is still visible: “Meta = physica / The<si>bus (¿?) diß/” [?]). In the left margin, on the lower half of p. 338 an odd shape is designed with a blunt punch (?). Two circles “holding up” a kind of inverted triangle, with a close splitting line into a trapeze and another triangle.    

.- p. 340-343: bifolium; book cover (p. 340 and 343 inner part; p. 341-342 outer part).  

.- p. 346-347: Three sewn strips, two out of them seem to have been used as book cover, with triangle-shaped cuts in order to remove its tips and folds.  Sets 1,2 and 3 from the current inside out : 2 (346 inner part, 347 outer part, folds towards the inside cover) 3 (346 outer part, folds towards the inside cover; 347 inner part) An animal’s head is drawn in this third set.  

.- p. 348-351: they could have been used as another book cover, whose size would be similar to that of the aforementioned. Its outer parts are pp. 349-350. They do not make up a bifolium, but two leaves sewn to parchment scraps (?) (cfr. infra)  

.- pp. 348-349 have been slightly cut in their outer margin. The first one is placed 50mm away from the current top edge (12mm) and the second (10mm) set in 92mm from the tip of the first and 50mm from the current outer edge of this side of the folio.  Next to this second one, an oxide stain (?) can be seen about 10mm across inwards on p. 348. At the same level of the first one there is a symmetrical cut with the fold of the edge as an axis, what could be understood as closure system. Similarly levelled signs can be observed on pp. 350-351.  

.- Offsets from other texts remain on pp. 353-354 (the surface marked by folds is a rectangle that lies on both leaves, around 310mm long, 205-215 high, depending on where they are measured). The offset of the text on page 353 (its lines are upright concerning the current page format) appears to be gothic with ca. 8-9 line spacing. The offset of a column visible on the outer margin on page 354 could be suitable with VL fragments from csg 1398b (line spacing is 7-8mm wide).

These manuscript fragments were collected by I. von Arx in 1822 together with many others preserved under the signatures csg 1394 to 1399. They were probably rebound as a separate book ca. 1940, when J. Duft was librarian at Sankt Gallen.

pp. 338-339 + 344-345 and pp. 340-343  have been used as book covers for some philosophical treatises:

.- pp. 338-339 + 344-345 (bifolium): book cover (pp. 338 and 345 were the inner part, and 339-344 the outer). On the bottom of pp. 344 and 339 (upside-down) part of the title written on the original spine is still visible: “Meta = physica / The<si>bus (¿?) diß/” (17th-18th c.?)

.- pp. 340-341 + 342-343 (bifolium): book cover; part of the title written on the spine is still visible (p. 341-342, inner margins): “Phy = sicae uite (¿?) / Pars (¿?) 3tia / Anima (¿?)”(same hand, 17th-18th c.?)
