Yukio Iwakuma’s "Website" on Logical Manuscripts (circa 800-1220)

Over an academic career spanning more than forty years, Professor Iwakuma collected information on Latin logical manuscripts from circa 800 to circa 1220. He wrote up basic but informed descriptions of the logical content of more than 700 manuscripts, wrote up lists of relevant material, and transcribed hundreds of logical texts, while also preparing the critical editions of Alcuin's "Dialectica" and of the "Ars Meliduna" (currently in progress; for a recent discussion see his "Struggles with Stemmatics" in Ad Placitum. Pour Irène Rosier-Catach, II, 395-402.

This section of the website hosts material that Professor Iwakuma wishes to make available freely to researchers in the field. At the moment, he is sharing his folder HPMss. The folder is first to be downloaded and then the file 'Home' provides the first entry into the material. This version was last updated on 27/05/2021.

Dating back to the 11th century, this is a major collection of texts pertaining to the liberal arts. Among many others, it includes Boethius's Latin translation of Porphyry's Isagoge, with glosses and diagrams, and Pseudo-Augustine's Categoriae Decem. For an analysis of some of these diagrams, see Caterina's The Latin Tradition of Studying Porphyry's Isagoge, ca 800‒980: A Catalogue of Manuscripts, Glosses, and Diagrams in AHDLMA 2020 (stemming from Christophe Erismann's 9SALT project Reassessing Ninth Century Philosophy. A Synchronic Approach to the Logical Traditions).

A recent article by Clelia Crialesi in The Journal of Medieval Latin edits the "Excerptiuncola", a short introduction to Boethius's De arithmetica, to be found on fols. 156v-157r of this important manuscript.

The full digitisation of this manuscript was funded as part of Caterina's research project.
