Musaeus of Marseilles

Musaeus of Marseilles (fl. c. 450) he was also an esteemed preacher whose sermons were read for edification. The sacramentary was a "sort of plenary missal", and is the earliest known of its kind. He was born in Massilia, once part of a Greek colony in southern France.

He probably put together this lectionary about 450. Gennadius goes on to state that this work proved indispensable for lectors in church. He also addressed to Eustathius, the successor of Venerius, an "excellent and sizable Book of Sacraments, divided into various sections according to the offices and time, according to the text of the reading, sequence of the psalms, and chanting, but proper for praying to God and asking for the multitude of His favours." The work has not survived. Gennadius also states that it was said that he also delivered homilies.
