The Costuma d'Agen (customary laws of the Agenais, in south-west

France) compiled in Occitan at various times in the thirteenth

century and preserved in the Livre Juratoire , or swearing copy

(Bibliothèque municipale d'Agen, MS 42), is here transcribed with an

English translation on facing pages. An introduction and an index are

included. Appendices provide the text of five chapters "missing" from this

manuscript, along with several pertinent charters from Agen and a fuller

description of the Livre juratoire by Professor M. Alison Stones, University of

Pittsburgh. The manuscript contains many colored illustrations and capitals.

The Costuma emphasizes the power of the local city council, which often

seems to override that of the local count. The laws or customs written in the

book deal with many topics including jurisdiction, citizenship and military

duties, crime, property, civil and criminal procedure, the local wine and salt

trades, and local feudal law.
