This work proposes a revision of the Greek corpus of alchemical manuscripts preserved in Italian libraries through the creation of a new and updated catalogue, compiled according to recent cataloging standards. This project responds to the need for a complete revision of the current catalogue of Italian alchemical manuscripts edited by Carlo Oreste Zuretti and published in Brussels in 1927 (Catalogue des manuscrits alchimiques grecs, II). The insufficiency of that work emerges in the description of individual items, especially with regard to codicological and paleographic aspects. The new careful study involving each manuscript aims at the realization of a comprehensive working tool capable of combining the material, scriptural, textual and historical-cultural aspects of each codex.
