Welcome to the Twelfth Century Logic Home Page.

This site is aiming at giving an exhaustive list of all the MSS which contain
1) the logica vetus and logica nova literature dating before ca. 1200.
2) logical treatises before ca. 1200.
3) treatises dealing with the division of philosophy before ca. 1200.

Many treatises still remains unedited; I shall give my transcriptions of them together with a survey of researches so far made.

To Colleagues


This site consists of three levels: I and II are accessible through various INDICES;
III through II, or shorter ones, directly through I or in II.
