Cresconius (bishop of Iria)

Cresconius, a Galician bishop, served as Bishop of Iria Flavia (present-day Padrón, Spain) during the 11th century. His episcopate is notable primarily for his role in documenting and potentially forging historical records pertaining to the Compostelan See and its claims of apostolic foundation by Saint James. He is often associated with the creation or manipulation of documents intended to bolster the authority and prestige of the Bishopric of Compostela, which sought to elevate itself above other Iberian sees.

While the specifics of Cresconius's involvement are debated among historians, he is often linked to the production of cartularies and other texts that reinforced the legend of Saint James's burial at Compostela and the associated ecclesiastical claims. The validity of some documents attributed to or influenced by him has been challenged, raising questions about their authenticity and purpose. He is a significant figure in the study of the early development of the cult of Saint James and the historical controversies surrounding it. He is believed to have held the position of Bishop of Iria from approximately 1036 to 1066.
