Brynjólfur Sveinsson (14 September 1605 – 5 August 1675) served as the Lutheran Bishop of the see of Skálholt in Iceland. His main influence has been on modern knowledge of Old Norse literature. Brynjólfur is also known for his support of the career of the Icelandic poet and hymn writer Hallgrímur Pétursson. Brynjólfur Sveinsson is currently pictured on the Icelandic 1000 krónur bill. 
In 1643, he named the collection of Old Norse mythological and heroic poems Edda. Brynjólfur attributed the manuscript to Sæmundr fróði, but the scholarly consensus is that whoever wrote the Eddic poems, whether in the sense of being the compiler or the poet, it could not have been Sæmundr. It is believed that the manuscript has multiple authorship from over a long span of time.
In 1650 King Frederick the Third appointed Bishop Brynjólfur to succeed the late Stephanius as Royal Danish Historian. He declined the post but promised the king to do what he could to collect manuscripts in Iceland. One of his first acts was to request all people residing in his diocese to turn over to the King any old manuscripts, either an original or a copy, as a gift or for a price. 
Among the most monumental of the Icelandic manuscripts thus collected is the Flateyjarbók, which was secured only after a personal visit to the owner from Brynjólfur. Jon Finnsson (Jóni Finnssyni) of Flatey, Breiðafjörður, who owned the manuscript, was initially unwilling to give up his precious heirloom. After a personal visit and persuasion from Bishop Brynjólfur, Finnsson gave up the valuable manuscript. The manuscript was given to King Frederick III in 1656, and placed in the Royal Library of Copenhagen.
