Luke the Evangelist is one of the Four Evangelists—the four traditionally ascribed authors of the canonical gospels. The Early Church Fathers ascribed to him authorship of both the Gospel of Luke and the Acts of the Apostles, which would mean Luke contributed over a quarter of the text of the New Testament, more than any other author. Prominent figures in early Christianity such as Jerome and Eusebius later reaffirmed his authorship.
Master E. S. (c. 1420 – c. 1468; previously known as the Master of 1466) is an unidentified German engraver, goldsmith, and printmaker of the late Gothic period. He was the first major German artist of old master prints and was greatly copied and imitated. The title, Master, is used for unidentified artists who operated independently. He was probably the first printmaker to place his initials on his work.
