Kven Sea

Kven Sea (Cwen sea) is mentioned as the northern border for the ancient Germania in the "The Old English Orosius", the history of the world published in England in 890 CE with a commission from King Alfred the Great himself. It was probably the same as the Gulf of Finland, although the Gulf of Bothnia have also been suggested.

Included in Orosius, there is a short mention of the Kven Sea by a Norwegian viking Ottar, but the Kven Sea is unknown outside Orosius.

Borders of the ancient Germania were described in Orosius as follows:

"From the Tanais (River Don) westwards to the Rhine, which takes its rise in the Alps, and runs northward, till it falls into that branch of the ocean which surrounds Bryttannia, and southward from the Tanais to the Donua or Danube, whose source is near that of the Rhine, and which runs to the northward of Greece, till it empties itself into the Euxine, and north even to that part of the ocean which is called the Kven Sea (Cwen sea), there are many nations; and the whole of this extensive country is called Germania."
