The Recueil des inscriptions gauloises (RIG) is a comprehensive collection of Gaulish language inscriptions. The RIG gives archaeological context, images of the inscriptions, alternative readings, and commentary on each inscription. Inscriptions of only one word are usually excluded. The inscriptions collected date between the 2nd century BCE and the 4th century CE.[1][2][3]
Each inscription is given a letter (L, E, or G, depending on whether the inscription is written in the Latin, Etruscan or Greek alphabet) and a number (e.g., G-159, L-3). Exceptions to this system include RIG III A and RIG III B, the Coligny and Villards-d'Héria calendars, which have their own volume; and the inscriptions on coins in RIG IV, which are just given numbers.[1][2]
The project was first announced by Paul-Marie Duval in 1959.[4] The first volume was first published in 1985 by Michel Lejeune. After Lejeune, the project was taken over by Pierre-Yves Lambert. The last volume was completed in 2002. A number of supplements to the volumes have been published in Études celtiques.[2][3] In 2020, a computerised version of the RIG was begun, the Recueil informatisé des inscriptions gauloises (RIIG). The RIIG has an updated numbering system.[1]
