He came into conflict with the French king, Philip Augustus, over Philip's intended repudiation of his wife[2].
He continued the building work on Notre Dame de Paris. He is considered the first to have emphasized the elevation of the Host during the Catholic Mass[3]. He in 1175 forbade communion for children[4]. Odo's decree on custody of reserved hosts, requiring a "clean pyx" was influential in England.
In surviving decrees, he as bishop is seen addressing a number of social matters. He attempted to regulate celebrations in his cathedral[5], Christmas[6] and the Feast of Fools[7]. He also tried to ban chess[8].
He is known too for his promotion of polyphony in church, and the music of Pérotin.[9].
He was a founder of the abbey that became Port-Royal[10].
His predecessor, Maurice de Sully, was not a close family connection.
