Red Book of Ossory  The Red Book of Ossory is a medieval manuscript produced in Kilkenny, Ireland, and kept in St Canice's Cathedral. The manuscript contains a number of texts in Latin and in Anglo-Norman. The sixth gathering of the MS contains the "Proverbes de bon enseignement" by Nicholas Bozon. The Latin religious lyrics in the manuscript were intended to replace more secular songs in the vernacular, and were composed by Richard de Ledrede, Bishop of Ossory.
