Ulfilas

Ulfilas (Ancient Greek: Οὐλφίλας; c. 311 – 383), known also as Wulfila(s) or Urphilas, was a 4th-century Gothic preacher of Cappadocian Greek descent. He was the apostle to the Gothic people.

Ulfila served as a bishop and missionary, participated in the Arian controversy, and is credited with converting the Goths to Christianity as well as overseeing translation of the Bible into the Gothic language. For the purpose of the translation he developed the Gothic alphabet, largely based on the Greek alphabet, as well as Latin and Runic characters. Although the translation of the text into Gothic has traditionally been ascribed to Ulfila, analysis of the text of the Gothic Bible indicates the involvement of a team of translators, possibly under his supervision.
