Numenius lived in Egypt.
Muirchu moccu Machtheni -LRB- Latin  : Maccutinus -RRB- , usually known simply as Muirchu , was born sometime in the seventh century .. He became a monk in Leinster , and eventually , an Irish historian .. He is best known for his Vita sancti Patricii , known in English as The Life of Saint Patrick , one of the first accounts of the famous fifth-century saint , and which credits Patrick with the conversion of Ireland in advance of the spread of monasticism .. This work was dedicated to Bishop Aedh of Slebte , who was also the one who suggested the life be written , and was the patron for the work .. Muirchu 's work should not be dismissed as historically inaccurate because , though it can not positively tell us about the period in which Patrick lived , it does show us a lot about the period in which it was composed , the seventh century .. Therefore , most scholars agree that while several miraculous episodes are included , the work is probably as accurate as can be expected given the sources available .
