Digital Index of Manuscripts of Commentaries on the “Logica vetus” Dating to the 12th Century

The Index lists all relevant manuscripts considered in the ERC project “PolyphonicPhilosophy”. At the moment, there are 39 mss.

Aim of the Index: the overall aim of the project is to study each manuscript on the list. We will carry out in-depth codicological and paleographical analysis, as well as compile exhaustive descriptions of them. Each description will be based on the study of the manuscripts themselves. In this online list, we also aim at gathering all the digital material related to the manuscripts (such as digitization, and online descriptions, catalogues and bibliography).

Criteria for inclusion in the Index: any manuscript transmitting at least one logical commentary (even incomplete commentaries) written in Latin and dating to the 12th century. By ‘logical commentary’ we mean a commentary to one of the following texts of the so-called “Logica vetus”: Porphyry’s “Isagoge”; Aristotle’s “Categories” and “De interpretatione”; Boethius’s “De divisione”, “De differentiis topicis”, “De syllogismis hypotheticis”, “De syllogismis categoricis”. Manuscripts transmitting commentaries on Aristotle’s “Elenchi sophistici” are being considered in the appendix, as part of the ‘control group’.

Control Group

This additional list presents manuscripts that contain 12th-century logical materials, and not included above. In more detail, it lists 12th-century manuscripts that contain: commentaries and treatises on Aristotle’s “Elenchi sophistici”; 12th-century treatises on Dialectics, or other relevant logical treatises (such as Abelard’s “De intellectibus”); manuscripts of commentaries and notes on Priscian’s
“Institutiones grammaticae” belonging to the so-called Glosulae-complex and manuscripts, not of commentaries, but of the authoritative texts. 
The list is still provisional.

Aim of the Appendix: this additional group of manuscripts is intended as a control group. We are considering them in order to draw parallels in the analysis of codicological, paleographical, or even textual elements.
