Hmm. Nerd question (please bear with me): is this the language spoken by the Ostrogoths or the Visigoths?
The Ostrogoths (Eastern Goths) ruled an area stretching from southern France to western Serbia, encompassing Italy, from 493 AD to 553 AD. At that time, their kingdom was absorbed by the Byzantine general Belisarius into the burgeoning Byzantine Empire.
The Visigoths (Western Goths) ruled an area encompassing southwestern France (Aquitaine and Septimania) and most of the Iberian Peninsula, i.e. Spain and Portugal, from the 5th to the 7th century AD. Their kingdom was then conquered piecemeal by the invading armies of Islam.
The most fascinating thing? Trying to find out where the Goths came from. There were many guesses (e.g. Gotland in Sweden), but modern consensus places them in modern-day Ukraine. There are references to them in both Beowulf and the original 6th-century stories that eventually formed the Volsunga saga and others.
Shockingly, the story of the Goths does not end in the early Middle Ages. There was a long, long presence of Goths living in their original homeland, in the southern Crimean Peninsula, as late as 1778 (under the reign of Catherine the Great of Russia), with their own language, customs, and ways of worship. After 1778, though, they also disappeared from the historical record. It's possible that they intermingled and intermarried with the Crimean Tatars, and converted to Islam.
Sorry for my long post.

I'm a history nerd, as I'm sure you know!
