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 name assigned to him by art historians, Master E. S., is derived from the monogram, E. S., which appears on eighteen of his prints (variants appear on others). The title, Master, is used for unidentified artists who operated independently. He was probably the first printmaker to place his initials on his work. Remaining signed works by E. S. indicate that he was active in printmaking from 1450 to 1467, the latest date to appear on one of his prints. After this date, he is presumed to have died. He was the most distinguished German engraver before Martin Schongauer. Life Master E. S. probably came from southwestern Germany or Switzerland, as did the engraver called the Master of the Playing Cards. This view rests mainly on stylistic comparisons with the contemporary painting of that region. Although evidence indicates that he was most active in the Upper Rhine region, there also is evidence that he visited Mainz, to the south on the Rhine at the confluence of the Main River opposite Wiesbaden, a major economic and cultural centre. None of the attempts to match documented persons with his initials have met with general acceptance. The term master meant someone who had completed an apprenticeship and ran his own workshop, as E. S. clearly did. Marriage and employing apprentices to learn the skills could sometimes also be requirements. E. S. probably came from a background and training as a goldsmith, rather than as a painter. He sometimes used goldsmith punches in his prints (for example, to make the circles on the borders of the clothes in the Delilah print above) and some works are clearly designs for metalwork. He was the first printmaker to sign his prints with an engraved monogram, which was standard practice on significant pieces of metalwork. He engraved two images of Saint Eligius, the patron-saint of goldsmiths. He liked to fill his engravings with decorative detail, sometimes overloading the composition, and only slowly does a sense of volume or recession develop in his work. Since his earliest prints show a practiced use of the burin, he is presumed to have worked as a
