Quiz: Remember the definition of mal de mer?
in Christianity, a book containing portions of the Bible appointed to be read on particular days of the year. The word is also used for the list of such Scripture lessons.

During the 3rd and 4th centuries, several systems of lessons were devised for churches of various localities. One of the first attempts for a diocese to fix definite readings for special seasons during the year was made by Musaeus of Marseille in the mid-5th century.
