The Gesta episcoporum Leodiensium ('Deeds of the Bishops of Liège') is a history of the diocese of Liège written by the monk Gilles of Orval between 1247 and 1251.[1] At about the same time, Gilles also composed an epitome of his history, the Gesta episcoporum Leodensium abbreviata.[1] It was first edited by Johannes Heller for the Monumenta Germaniae Historica in 1880.[2]
Gilles sought to continue the earlier gesta of Heriger of Lobbes and Anselm of Liège from 1048 down to 1247.[3] As a historian, he was rather uncritical.[3] His is the earliest account to mention any children of King Zwentibold.[citation needed]
