Critical edition of the Latin works of the Catalan lay theologian and mystic Raimundus Lullus (1232/33?-1315/16?). The edition is expected to run to approximately 55 volumes.

​

Although Llull originally wrote much of his work in Catalan, most of it has been handed down in contemporary translations - sometimes encouraged by Llull himself. This edition relies primarily on the Latin tradition, which exists in handwritten and early printed forms; however, it also takes into account versions in other languages (Catalan, Old French, Old Spanish, and so on). Because the historic Editio Moguntina of Llull's works (Mainz, 1721-1742) focused primarily on the extensive early works in their Latin versions, this edition begins with the later works (which are less extensive and, for the most part, unedited), thereby providing a first edition. This edition includes works that have already appeared in the Editio Moguntina; in these cases, it provides a first critical edition. [Further reading]
