Synod of Rouen
The first synod of Rouen is generally believed to have been held by Archbishop Saint-Ouen about 650. Sixteen of its decrees, one against simony, the others on liturgical and canonical matters, are still extant.
Later synods were presided over by:
- Archbishop St. Ansbert some time between 689-93
- Archbishop Mauger in 1048
- the papal legate Hermanfrid of Sitten at Lisieux in 1055, at which Archbishop Mauger of Rouen was deposed for his loose morals
- Archbishop Maurilius in 1055, which drew up a creed against Berengarius of Tours to be subscribed to by all newly elected bishops
- Archbishop John of Bayeux, one in 1072 and two in 1074, urging ecclesiastical reforms
- Archbishop William in 1096, at which the decrees of the Council of Clermont (1095) were proclaimed
- Archbishop Goisfred in 1118, at which the papal legate Conrad asked the assembled prelates and princes to support Gelasius II against Emperor Henry V and his antipope, Burdinus (Gregory VIII)
- the same Archbishop in 1119, and the cardinal legate Matthew of Albano, in 1128, to enforce clerical celibacy
- Archbishop Gualterus in 1190, and the papal legate Robert de Courçon, in 1214 to urge clerical reform.
The last provincial synod was held by Archbishop Louis-Marie-Edmont Blanquart de Bailleul in 1830; for its Acts see Collectio Lacensis, IV, 513-36.
- Jean-François Pommeraye and a few others place this synod in the second half of the ninth century.
