inscription. The last part of the inscription is an alliterative poem. This kind of verse appears on several runestones and it is well known from Old West Norse poetry. Latin transliteration: : sbiuti : halftan : þaiʀ : raisþu : stain : þansi : eftiʀ : skarþa : bruþur sin : fur : austr : hiþan : miþ : ikuari : ą sirklanti : likʀ : sunʀ iuintaʀ Runic Swedish transcription: Spiūti, Halfdan, þæiʀ ræisþu stæin þannsi æftiʀ Skarða, brōður sinn. Fōr austr hēðan með Ingvari, ą̄ Særklandi liggʀ sunʀ Øyvindaʀ. English translation: "Spjóti (and) Halfdan, they raised this stone in memory of Skarði, their brother. From here (he) travelled to the east with Ingvarr; in Serkland lies Eyvindr's son." Sö 173 In the village of Tystberga there are three raised stones. Two of them are runestones called Sö 173 and Sö 374, of which the last one has a cross. Sö 173 is categorized as both style Fp and style Pr2. Both inscriptions are from the 11th century and tell of the same family. They probably refer to Viking expeditions both westwards and eastwards. The location was first described by Lukas Gadd during the nationwide revision of pre-historic monuments that took place in the 17th century. In a paddock at the state owned homestead of Tystberga there was a flat stone lying with runes and next to it there was another flat stone that was leaning. In addition, there was a large square stone surrounded with rows of smaller stones, which Gadd described as a "fairly large cemetery". Not far from the stones, there were also two giant passage graves, about 20 paces long. There is a depiction of the cross-less stone from the 17th century, made by Johan Hadorph and Johan Peringskiöld. This depiction has helped scholars reconstruct the parts that are damaged today. The runestone was raised anew by Richard Dybeck in 1864. In 1936, Ivar Schnell examined the stone, and he noted that there was a large stone next to it. When this stone was raised, they discovered that it was also a runestone, and it was probably the one that had been previously described by Lukas Gadd as the "square stone". In the vicinity, Schnell found a destroyed stone without runes which probably was the leaning stone described by Gadd. Since they would hinder agriculture, the three stones were re-erected at a distance of 60
