( fl c. AD 980–96). Ottonian illuminator. He is named after two detached leaves of a manuscript of the Registrum Gregorii (984; Trier, Stadtbib., MS. 117/1626, and Chantilly, Mus. Condé, MS. 14 bis) given by Egbert, Archbishop of Trier, to Trier Cathedral. Work in a group of late 10th-century codices, most of them produced for churches in Trier between 980 and 996, is also attributed to this artist. A Sacramentary made for Lorsch Abbey, perhaps c. 980 (Chantilly, Mus. Condé, MS. 1447), may be among his earliest works, while his last known work is a Gospel Book in Manchester (John Rylands U. Lib., MS. 98). Its miniatures are now missing but are attributed to the Gregory Master on the grounds of the full-page incipits to the Gospels, characteristically laid out with medallions of emperors in square frames in the borders. Since Otto III is portrayed as an emperor, the manuscript cannot have been produced before 996, the date of his imperial coronation. The Master has also been linked with Ottonian ivory-carving (see OTTONIAN ART, §VI).
