[2] In his Ynglinga saga, Snorri Sturluson relates that Anund succeeded his father King Yngvar who fell in battle with the Estonians.
[4] One autumn, King Anund was travelling between his halls (see Husbys) and came to a place called Himinheiðr (sky heath) between two mountains.
After presenting this story of Anund, Snorri Sturluson quotes Þjóðólfr of Hvinir's Ynglingatal: The Historia Norwegiæ presents a Latin summary of Ynglingatal, older than Snorri's quotation (continuing after Ingvar Harra): Iste ergo genuit Broutonund, quem Sigwardus frater suus occidit in Himinheithi,[6] quod loci vocabulum interpretatur coeli campus.
After him his son Ingjald [...][8] The original text of Ynglingatal is hard to interpret, and it only says that Anund died und Himinfjöllum (under the sky mountains) and that stones were involved.
According to Historia Norwegiæ, he was murdered by his brother Sigvard in Himinherthy (which the source says means "the fields of the sky", cœli campus).
