Passage: Gothic is an extinct East Germanic language that was spoken by the Goths. It is known primarily from the Codex Argenteus, a 6th-century copy of a 4th-century Bible translation, and is the only East Germanic language with a sizable text corpus.  All others, including Burgundian and Vandalic, are known, if at all, only from proper names that survived in historical accounts, and from loanwords in other languages such as Portuguese, Spanish, and French.

Question: The gothic language is most prominently known of for what text?
