Odo I of Beauvais

Odo I (or Eudes I) was a West Frankish prelate who served as abbot of Corbie in the 850s and as bishop of Beauvais from around 860 until his death in 881. He was a courtier and a diplomat, going on missions to East Francia and the Holy See.

He wrote a lost treatise on Easter against the Greek practice. He also wrote a passion of Saint Lucian, modelled on the hagiographical work of Hilduin, and was the first to portray Lucian as the founding bishop of Beauvais.
