Collectio canonum Wigorniensis

The Collectio canonum Wigorniensis (also known as the Excerptiones Ecgberhti or as "Wulfstan's canon law collection") is a medieval canon law collection originating in southern England around the year 1005. It exists in multiple recensions, the earliest of which — "Recension A" — consists of just over 100 canons drawn from a variety of sources, most predominantly the ninth-century Frankish collection of penitential and canon law known as the Collectio canonum quadripartita.
