The runic inscription Ög 197 is a Viking Age runestone that now stands in the churchyard by the old church ruin of Sörby in Mjölby parish and Mjölby Municipality, Östergötland. The stone previously lay embedded in the eastern churchyard wall before it was removed and raised at its current location. The material is reddish granite, and it is carved with normal runes that run in a closed loop, meaning the inscription goes all the way around without a clear beginning or end. The runic text is read from right to left, and the runes themselves are mirrored compared to how they usually appear in Viking Age runic inscriptions. Diagonal crosses were used as separators between words. On the western side, the stone is supported with iron braces. The runes can be translated as: Vigot raised these stones in memory of Torgot, his brother. Original height: 2,64 m Width: 1,10 m.
