The Paenitentiale Ecgberhti (also known as the Paenitentiale Pseudo-Ecgberhti, or more commonly as either Ecgberht's penitential or the Ecgberhtine penitential) is an early medieval penitential handbook composed around 740, possibly by Archbishop Ecgberht of York.
This work should not be confused with the vernacular works known as the Old English Penitential (formerly the Paenitentiale Pseudo-Ecgberhti) and the Scriftboc (formerly the Confessionale Pseudo-Ecgberhti). Manuscripts and Transmission There are eleven extant manuscripts that contain the Paenitentiale Ecgberhti, dating from as early as the end of the eighth century to as late as the thirteenth, ranging geographically from southern Germany to Brittany to England. The sigla given below (V6, O1, etc.) are based on those established by the Körntgen–Kottje Editionsprojekt for the Corpus Christianorum, Series Latina, vol. 156, a project whose goal is to produce scholarly editions for all major early medieval penitentials; sigla in parentheses are those used by Reinhard Haggenmüller in his 1991 study.
