A TREASURE TROVE OF CHRONOLOGICAL LEARNING[Note 1. I wish to thank Piotr Wilczek for his comments, ...]

ABSTRACT The recent facsimile edition of Henricus Glareanus's Chronology of Livy, prepared by Anthony T. Grafton and Urs B. Leu, provides access to a primary source that is unique from the point of view of the history of science and scholarship and of the book and reading. The basis of the edition, a copy of Chronologia annotated by Glareanus's disciple Gabriel Hummelberg II, now preserved at the Princeton University Library, serves scholars both as a point of departure for outlining hypotheses on the teaching methods of early modern humanists as well as the role of chronology in the humanist curriculum. My reading of their edition is based on three points. First, I put the primary source of their choice in a context that includes provincial early modern educational centers as I believe that their enterprise could clear the way for future narratives on forgotten scholars who dealt with the issues of technical chronology. Second, I show the importance of Grafton and Leu's thesis on the procedures of transmission of teachers’ commentary, which, according to them, is documented by the Princeton copy of Chronologia . Third, I argue that the seemingly conservative decision to publish a paper edition of an annotated volume at the moment when state‐of‐the‐art digital tools for such editions are being tailored through the alliance of scholars and IT specialists should open a discussion among historians of the book and reading, science, and education that would lead to the determination of standards for scholarly editions of libri annotati .
