BARTHOLOMEW OF PISA, Summa de casibus

The author is also known as BARTOLOMEO DE SAN CONCORDIO and his text as Pisanella, ed. in an unlocalized Italian edition (20 October 1473; Hain 2526*, BMC 7:1123); see Kaeppeli, 1:157–68 (no. 436, completed 1338) and Pierre Michaud-Quantin, Sommes de casuistique et manuels de confession au moyen âge (XII–XVI siècles), Analecta medievalia Namurcensia 13 (Louvain, 1962), 60–2. The remainder of the MS is blank, but both fols. iii and iv are ruled, and the medieval front flyleaf (fol. ii) has at least the imprint of rules.

Physical Description

Secundo Folio: -dere potest
Form: codex
Support: Vellum (FSOS/FHHF).
Extent: Fols. ii + 180 (numbered fols. 1–178, iii, iv) + i (numbered fol. v).
Dimensions (leaf): 310 × 210 mm.


1–108, 118 (–8, a stub) 128 138(–8) 14–228 238 (–7, –8, both blank). Catchwords, underlined or three-quarter boxed, one (fol. 95v) in a scroll, under the inner column; no signatures.


In double columns; after quire 1, each column usually about 230 × 70 mm. , with 14 mm between columns, in 45 or 46 lines to the column. No prickings; bounded and ruled in black and brown ink.

Scribe 1's format in the first quire deviates from the remainder; he writes in double columns, each column 230–5 × 70 mm. , with 15 mm between columns, in 41 lines to the column.


Written in anglicana (with secretary a). There appear to be at least four scribes, the first two working in near concert. Generally speaking, however, the production is consonant with a divided exemplar having been distributed among various copyists; some effort seems to have been made to disguise exchanges between one copyist and another by making the same scribe copy a full opening across quire boundaries. Punctuation by point and virgula.

Scribe 1 copied fols. 1–12va, 16, and most of 17v–40 (quires 1, 3–5).

A different hand, not apparent elsewhere, has written a little on fol. 3rab, and the next scribe writes intermittently in later parts of scribe 1’s stint.

Scribe 2 copied fols. 12va–15vb, 17, intermittent sections through to fol. 40, and 40v–87v (quires 6–11). The end of his stint corresponds with a cancelled final leaf, presumably the result of inaccurate ‘casting off’ of the supply of text.

Scribe 3 copied only fols. 88–96 (quire 12).

Scribe 4 copied the remainder, fols. 96v–178v (quires 13–23); his work may actually have begun with quire 14, and he may have filled in quire 12 to join with scribe 3, since yet another cancelled leaf occurs at its end (following fol. 102).


At the head of the prologue and of individual letters in the alphabetically arranged text, 3- and 4-line blue lombards on red flourishing.

Individual entries headed by 2- and 3-line red lombards on red flourishing; the argument divided by red paraphs.


A modern replacement. Sewn on five thongs. At the front, one modern paper flyleaf and one medieval vellum flyleaf; at the rear, one modern paper flyleaf (v).
