Musaeus, presbyter of the church of Marseille, a man learned in the Divine Scriptures and most subtle in their interpretation, a scholar by language. At the request of the venerable Bishop Venerius, he selected from Holy Scriptures passages suited to the various feast days of the year, and also responsories from the psalms according to the time [of the year] and [current] readings. This work proved indispensable to the lectors in church, as it saved them trouble and anxiety in the search for passages, and was useful for the instruction of the people as well as for the dignity of the service.
He also addressed to the venerable Bishop Eustathius, successor to the above-mentioned man of God, 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. By this work, we know him to have been a man of most serious understanding and severe eloquence. He is said to have also delivered homilies, which are, as I know, valued by pious men, but which I have not read. He died in the reign of Leo and Majorianus.
