The Lilla Vilunda runestones are three Viking Age memorial runestones that were erected by members of the same family and which are located at Lilla Vilunda (also known as Stallgatan) in Upplands Väsby, , Sweden, and in the historic province of Uppland.
Runic inscription U 293 is the Rundata catalog number for an inscription on a gneiss stone that is 1.8 meters in height. This stone was identified during the runestone surveys conducted in Sweden during the 17th century by Johannes Bureus and Johannes Rhezelius. The inscription consists of runic text carved on a serpent that encloses a Christian cross. The inscription is classified as being carved in runestone style Pr3 or Pr4, which is also known as Urnes style. This runestone style is characterized by slim and stylized animals that are interwoven into tight patterns. The animal heads are typically seen in profile with slender almond-shaped eyes and upwardly curled appendages on the noses and the necks. For stylistic reasons, the inscription has been attributed to the runemaster Visäte, who was active during the last half of the 11th century in southern Uppland. Eight surviving runestones that are signed by Visäte include U 74 in Husby, U 208 in Råcksta, U 236 in Lindö, U 337 in Granby, U 454 in Kumla, U 669 in Kålsta, U 862 in Säva, and U Fv1946;258 in Fällbro, and over twenty others have been attributed to this runemaster based on stylistic analysis.
The runic text states that the stone is a memorial raised by two brothers named Forkunnr and Þórir in memory of their father Ketill. Readers of the text would consider Forkunnr to be the elder brother as he was listed first. Consistent with the cross in the inscription, the text ends with a prayer for the soul of Ketill. The composition emphasizes the runes for ant ' hns meaning and hans ("his spirit") by placing the words on the extension that rises up to the bottom of the cross. The inscription also uses the word stæina or stones, suggesting that a second memorial stone was also raised. Nearby to this runestone is a cemetery with a tall menhir, and it has been suggested that the use of the plural stones refers to this stone.
