The runic inscription on the Fyrby Runestone consists of runic text within a band that curves along the face of the north side of a granite boulder that is two meters in height. The runic inscription is classified as being carved in runestone style RAK. RAK is the classification for the oldest style where the ends of the runic bands are straight and there are no animal designs. The inscription is considered somewhat enigmatic due to its use of the pronoun I at the beginning of the runic text, which might even refer to the stone itself speaking to the reader. This runestone is notable for its reference to Midgard (Middle Earth), which was one of the nine worlds of Norse cosmology and the home of humans. The period that Anne-Sofie Gräslund proposed for the RAK style was 990-1010 AD.
