Orkneyinga saga
Ohthere's mention of the "large [freshwater] meres" and of the Kvens' boats are of great interest. The meres are said to be "amongst the mountains", the words used in the text being "geond þa moras". Ohthere may be referring to the Southern Norwegian lake district, which is also referred to in "Orkneyinga saga". This way, the reference would have included Lake Mjøsa, an area which is known to have been inhabited at that time: the Orkneyinga saga tells how these inhabitants were attacked by men from Kvenland.
