Huldar saga
Huldar saga is the name of a lost Icelandic saga said to have been told by Sturla Þórðarson in 1263. Though the saga is no longer extant, the account of its telling has attracted extensive commentary as a rare account of medieval Icelandic saga-performance.
Huldar saga is also one of the names of at least one post-medieval Icelandic saga in the same genre.
Sturla Þórðarson's ''Huldar saga''
This medieval Huldar saga is mentioned in Sturlu þáttr, a short tale about Sturla Þórðarson that survives only in the version of Sturlunga saga attested in the manuscript Reykjafjarðarbók, indicating that it does not belong to the written archetype of the saga. It depicts Sturla winning the favour of King Magnus VI of Norway through his storytelling; in this, it is similar to many of the Íslendingaþættir. It is assumed that the saga was akin to the fornaldarsögur, but there is debate as to whether Sturla knew it only orally or whether it was ever written. It has been suggested that the eponymous Huld is identical to a character in Ynglinga saga, but this is not certain. The passage is noted as a rare account of medieval Icelandic saga-performance, composed only about thirty-five years after the event is claimed to have taken place. It also seems to witness the existence of a lost *Huldar saga.The context for the passage is that King Hákon IV of Norway is on campaign in Scotland. Learning that Hákon's son Magnús is now ruling in Norway, an impoverished Sturla decides he needs to ingratiate himself with the new king. He sails to Bergen, but is not received warmly by Magnús, who merely promises not to kill him. Magnús then has Sturla accompany him and the court on a voyage southwards.
