The Visigoth (Therwinger) Wulfila (lat. Ulfilas; 311-383) was a missionary and Arian bishop of the Gothic kingdom in the Roman empire. He was born in a village in Muntenia north of the lower Danube, thus in ancient Dacia (now Rumania). Besides Gothic, he spoke Greek and Latin. To the Dacian-Roman population, he preached in Latin. In the province of Moesia (what is now northern Bulgaria), Wulfila was bishop of the Visigoths. His task was it to christianize these heathens. However, as a consequence of his mission among the Goths, he had to flee, in 348-350, with a handful of believers, from the heathen Gothic chiefs. The group settled at Nicopolis ad Istrum (Lower Moesia, now central Bulgaria). There Wulfila translated the Greek septuagint into Gothic.
What we have from Wulfila's translation is not the original, but only incomplete copies. One of these is the Codex Argenteus, produced in the 6th cent. in Ostrogothic Italy. The manuscript consists of purple-tainted parchment with silver letters – and with golden letters in the silver binding –, from where it got its name of “Codex Argenteus”.
The text specimen is the paternoster (Mt. 6, 9-13) from the Gothic bible.
