Papias of Hierapolis – Papias (Greek: Παπίας) was a Greek Apostolic Father, Bishop of Hierapolis (modern Pamukkale, Turkey), and author who lived c. 60 – c. 130 AD.[2][3] He wrote the Exposition of the Sayings of the Lord (Greek: Λογίων Κυριακῶν Ἐξήγησις) in five books. This work, which is lost apart from brief excerpts in the works of Irenaeus of Lyons (c. 180) and Eusebius of Caesarea (c. 320), is an important early source on Christian oral tradition and especially on the origins of the canonical Gospels.
