Ulf of Borresta (Old Norse: Ulfr í Báristöðum, modern Swedish: Ulf i Borresta) was a runemaster in the eleventh century Uppland, Sweden, and a successful Viking who returned from England three times with a share of the Danegeld. He is named after his estate which in modern Swedish is called Borresta or Bårresta (Old Norse: Báristaðir[1] or Bárastaðiʀ[2]).
Ulf belonged to a clan in what is today the parish of Orkesta, located in present-day Vallentuna Municipality, and he was the paternal nephew and successor of a man named Ónæmr,[3] a name which means "slow learner". Ónæmr is mentioned on several runestones, U 112, U 336 and probably U 328[3] (which is an example of the Ringerike style.[4]). The name of Guðlaug's father on U 328 is interpreted as Ónæmr, and Guðlaug had a son named Holmi who fell in Italy which is mentioned on the runestone U 133.[5] Another cousin of Ulf named Ragnvaldr was the commander of the Varangian Guard in Constantinople and made the runestone U 112 in memory of himself and his mother, Ónæmr's daughter.
Ulf made the runestone U 328 and also the runestone U 336 in memory of his uncle Ónæmr which today is raised at the church of Orkesta.[1] He also made the runestones U 160 and 161 for his kinsmen-by-marriage in Skålhammar (Old Norse: Skulhamarr).[1]
There were two runestones (runestone U 344 and runestone U 343) which were raised in Ulf's memory and they were raised together as a monument at Yttergärde. U 343 has disappeared but U 344 is now raised at the church of Orkesta.
The runestone U 344, in the style Pr3, was found in 1868, at Yttergärde, by Richard Dybeck.[6] It can be dated to the first half of the 11th century because of its use of the ansuz rune for the a and æ phomenes, and because of its lack of dotted runes.[7]
This stone is notable because it commemorates that Ulf had taken three danegelds in England.[6] The first one was with Skagul Toste[8] in 991,[5] the second one with Thorkel the High[8] in 1012[5] and the last one with Canute the Great[8] in 1018.[5] Since there were many years between the danegelds, it is likely that Ulfr returned to Sweden after each danegeld to live as a wealthy magnate.[9] It is a remarkable feat in itself to summarize Ulf's adventurous life in so few unsentimental words.[8][9]
The runestone U 343 reports Ulf's death and it was raised in his memory by his sons Karsi and Karlbjörn.[8]
