Aun the Old (Old Norse Aunn inn gamli, Latinized Auchun, Proto-Norse *Audawiniʀ: English: "Edwin the Old") is a mythical Swedish king of the House of Yngling in the Heimskringla.
Ruling from his seat in Uppsala, Aun was reputedly a wise king who made sacrifices to the gods.
Aun fled to the Geats in Västergötland, where he stayed for 25 years until Halfdan died in his bed in Uppsala.
Ok sveiðurs at sér hverfði mækis hlut inn mjávara, es okhreins ôttunga rjóðr lǫgðis odd liggjandi drakk.
[3] The Historia Norwegiæ presents a Latin summary of Ynglingatal, older than Snorri's quotation (continuing after Jorund): Iste genuit Auchun, qui longo vetustatis senio IX annis ante obitum suum densæ usum alimoniæ postponens lac tantum de cornu ut infans suxisse fertur.
Auchun vero genuit Eigil cognomento Vendilcraco [...][4] He became the father of Aukun, who, in the feebleness of a protracted old age, during the nine years before his death is said to have abandoned the consumption of solid food and only sucked milk from a horn, like a babe-in-arms.
