Supplement to the National Edition of Galilei’s Works

The Updated Supplement to the National Edition completed by Antonio Favaro in 1909 has been sponsored by the Ministero dei Beni e delle Attività Culturali e del Turismo. It is being published by Giunti Editore under the scientific direction of Museo Galileo and includes four volumes.


Vol 1: Iconografia galileiana, edited by F. Tognoni
Florence, Giunti, 2013, 608 pp. + 16 pp. of colour plates

The book features the most complete collection of images related to the Tuscan scientist ever published, including portraits, commemorative medallions, miniatures, and sculptures, which span across four centuries. The 335 entries outline the story of each work of art and offer information about materials and techniques as well as a detailed bibliography.


Vol 2: Carteggio, edited by M. Camerota and P. Ruffo, in collaboration with M. Bucciantini
Florence, Giunti, 2015, 664 pp.

This book features letters which were published after Favaro’s National Edition had been completed, over 100 years ago. It includes unpublished letters discovered through the systematic exploration of archives and libraries carried out as part of this project. The 588 letters collected in this volume supplement the correspondence edited by Favaro and make it possible to fill in significant gaps.


Vol 3: Testi, edited by A. Battistini, M. Camerota, G. Ernst, R. Gatto, M. Helbing, and P. Ruffo
Florence, Giunti, 2017, 280 pp.

Just a very few Galileo’s texts were not included in the National Edition edited by Antonio Favaro, who left them out since he thought them to be not very important. The Updated Supplement’s editors decided to voice all Galileo’s interests and publish also the works that have been excluded. This volume includes the following chapters:

Quaestiones de praecognitionibus et praecognitis. Tractatio de demonstratione, edited by M. Helbing
Astrologica nonnulla
, edited by G. Ernst
La “versione breve” delle Mecaniche di Galileo Galilei, edited by R. Gatto
Discorso del flusso e reflusso del mare, edited by M. Camerota and P. Ruffo
Le postille petrarchesche di Galileo, edited by A. Battistini


Vol 4: Documenti, edited by M. Camerota and P. Ruffo

The fourth volume, to be published in 2018, will mark the conclusion of the Updated Supplement. It will collect unpublished documents that were not included in the National Edition edited by Favaro.
