Page "Flateyjarbók" Paragraph 2

The Flatey Book is the largest medieval Icelandic manuscript, comprising 225 written and illustrated vellum leaves.

It contains mostly sagas of the Norse kings as found in the Heimskringla, specifically the sagas about Olaf Tryggvason, St. Olaf, Sverre, Hakon the Old, Magnus the Good, and Harald Hardrada.

But they appear here expanded with additional material not found elsewhere ( some of it being very old ) along with other unique differences.

Most — but not all — of the additional material is placed within the royal sagas, sometimes interlaced.

Additionally, the manuscript contains the only copy of the eddic poem Hyndluljóð, a unique set of annals from creation to 1394, and many short tales not otherwise preserved such as Nornagests þáttr (" the Story of Norna Gest ").
