Dimensions 305 x 217 mm.

Grand copy of “recollectae”(student notes) of the courses held by the canonist Mariano Sozzini in Siena between 1451 and 1454 on the Decretals of Gregory IX. Apart from its great rarity (three manuscripts, no copies in the Schoenberg Database), the interest of this collection -- lacking a modern critical edition -- lies in the many contemporary mariginalia, the method of copy and assembly, with at least a dozen different scribes, and the frequent colophons. This is a fine example of book production in late medieval Siena associated with the famous Studium.


1. Copied in Italy, by a number Italian hands, on paper with watermarks that clearly point to Italian paper stocks. This is in keeping with the content of this manuscript, which contains fair copies of notes taken by students of lectures heard in Siena between 1451 and 1454. The colophons reveal the dates the courses were held by Marianus Sozzinus, and there is little reason to believe these courses were copied much later than when they were delivered.

2. European Continental Collection.

Eternas (?) ego laus deo finis est” [for Gregory IX, Decretal (X. 2. 6) see Friedberg, 1881, col 258 et sqq.; “recollecta” published in Lyon, 1547];

This manuscript contains contemporary recollectae or repetitiones of the courses held by Mariano Sozzini on the Decretals, collected by students who attended the courses between 1451 and 1454 in the Studium at Siena. The name of Mariano Sozzini, author of these recollectae, is repeated a number of times in the numerous colophons that pepper this codex (ff. 177v, 325v, 430, 430v, 432 et passim).

Marianus Sozzinus was the father of Bartolomeo di Mariano Sozzini (1436-1507). The former was an important canonist in Siena and a reputed humanist; the latter was called in his day “the first and most famous doctor of all Italy”, a leading professor of law (canon and civil) in Italy in the fourteenth and fifteenth century, much sought-after and also involved in diplomacy and politics (on the son Bartholomeo Mariano, see R. Bargagli, 2000). Hence, Marianus Sozzino (1397-1461) is not to be confused with his more famous son Bartolomeo di Mariano Sozzini (Mariano Sozzini il Giovane).

A famous canonist, Mariano Sozzini began attending the law courses offered at the Studium in Siena in 1418. There he followed the courses of Niccolo dei Tedeschi, took his doctorate in utroque in 1427, and also developed a deep friendship with Aeneas Silvio Piccolomini (who would become Pope Pius II). With the departure of his master Tedeschi, Mariano Sozzini was promoted to teach the Decretals of Gregory IX. His son Bartholomeo evidently benefited from these relations for his own intellectual development and career.

The present manuscript refers to itself as containing “recollectae” (see colophon f. 492v). Recollectae, recollectiones, reportata, reportationes, additiones, and suppletiones are names given to the copies or notes taken by students at lectures or disputations. The reportator quotes the word of the text, additiones contain other people’s additions to the original, and when a professor takes another author’s text in class and adds to it, the result is suppletiones.

This particular series of recollectae or reportationes is based on tituli taken from the start of Book II of the Decretals of Gregory IX. Mariano Sozzini is known to have started the examination of tituli 2-7 of Book II of the Decretals after 1450 until c. 1457 when he was forced to flee Siena for a short period (see Nardi, 1974, pp. 83-84). The fact that the present manuscript contains notes taken during courses accounts for the variety of hands. These are not rough copies, as there are very few passages crossed-out or mistakes corrected; rather the students (we distinguish at least a dozen different hands) have provided fair copies of the courses as they were delivered between 1451 and 1454. Once bound together, one had the Master’s “complete” recollectae on the first tituli of Book II of the Decretals. Hence, this manuscript appears to be the result of a “common effort”, with each quire entrusted to a steady hand. When the text seems to break off with the beginning of a new quire, the scribe reassures the reader: “nichil deficit” [nothing is missing] (ff. 223v, 312v et passim). Unfortunately the colophons remain anonymous, although they systematically refer to Mariano Sozzini (commonly “Laus deo clementissimo Marianus Sozzinus”), and at the very end he is said to be the author of the copied “recollectae” (see colophon, f. “Laus deo clementissimo Marianus Sozzinus de Senis dedit has recollectas a die prima novembris 1451 usque ad diem [space left blank] 1454” [Glory be to God most clement, Marianus Sozzinus of Siena has given (delivered) these recollectae from 1 November 1451 to 1454]). The dates in this manuscript fit with the chronology of the works attributed to Mariano Sozzini, as indicated by Nardi (1974): “1452, [...] Commento sul tit. De foro competenti (X. 2. 2.); 1453, Commento sul De libelli oblatione et il De mutuis petitionibus (X. 2. 3-4); 1454, Commento sul tit. De iuramento calumniae e sul De litis contestatione” (Nardi, 1974, pp. 183-184).

A list of all the works (some 45 commentaries on various parts of Canon law) attributed to Mariano Sozzini the Elder and the extant codices is found in Nardi (1974, pp. 150-164) who supplies the best (and for now the only) intellectual biography of Mariano. Nardi’s student R. Bargagli (2000) did the same for the son Bartholomeo Mariano. Nardi lists the sixteenth-century editions of the collective works (including the collected recollectae or repetitiones) by Marianus Sozzinus: “Trattati e repetitiones sul II libro delle Decretali” (see P. Nardi, 1974, pp. 173-174): Pavia, 1514: “Marianus Sozinus super decretales...Tractatus de foro competenti, Tractatus de libelli oblatione; Tractatus de litis contestatione; Tractatus de mutuis petitionibus...”; Lyon, 1533; Lyon, 1547; Francfurt, 1583.

There are apparently three other codices that contain either all (as found in our manuscript), or only certain or other additional recollectae on the tituli from Book II of the Decretals, listed by Nardi (1974), pp. 152-155. These are: Lucca, Biblioteca Capitolare Feliciana, cod. 397, ff. 12-228, “Lect. Super quibusdam titulis libri II Decretalium” (X. 2. 2-5); the same text in Bologna, Biblioteca del Collegio di Spagna, cod. 215, ff. 56-280; - Vatican, BAV, cod. Ross. 840, ff. 244v-256v, “Rep. Quod di super rebus et Si autem in c. Quoniam frequenter, Ut lite non contestata (X.2.6.5, 7-8), with a colophon very close to the one in the present manuscript: “Laus deo clementissimo Marianus Sozzinus de Senis dedit has recollectas a die prima novembris 1451 usque ad diem 1454 quas ego Firmanus domini Angeli de Guidonibus de Perusio sub eo scripsi. Laus Deo”; the same text in Lucca, Biblioteca Capitolare Feliciana, cod. 397, ff. 252-266. In addition, for information an example of Marianus Sozzino’s own hand is found in Ascheri (ed.), 1996, fig VII, p. 26 (Archivio dell’Università, ms 1., f. 76v: “Sottoscrizione autografa e sigillo di Mariano Sozzini”). Are some of the annotations in this manuscripts by the hand of the Master? Only an in-depth investigation of the codices might allow for further conclusions.

The division of labor found in this manuscript is quite interesting, and the scribes have tried hard to make sure the text flows even if there are so many different hands at work. Similar colophons in other codices seem to point to a common milieu of production for these fair copies of Sozzini recollectae or reportationes. Proper comparison of the extant manuscripts and also a larger study on “recollecatae” (how they were assembled, who copied them, how the fair copies were put together, who annotated them) would certainly prove enlightening. This is a wonderful manuscript for the student of canon law, both for the material lay-out and its content.
