Birka - Adam of Bremen's Birka

Adam of Bremen's Birka

In Gesta Hammaburgensis ecclesiae pontificum (Deeds of Bishops of the Hamburg Church), Adam of Bremen mentions Birka many times, and the book is the main source of information on the city. After its initial release in 1075/6, Gesta was complemented with supplementary Scholias until the death of Adam in the 1080s. Birca is described as an existing city in the original version, but then as destroyed in Scholia 138.

One of Adam's main sources had been the German bishop Adalvard the Younger of Sigtuna and later of Skara as hinted in Scholia 119. He was also very familiar with Rimbert's work. Adam himself never visited Birka.
