The Rök Runestone is one of the most famous runestones, featuring the longest known runic inscription in stone. It is considered the first piece of written Swedish literature and thus it marks the beginning of the history of Swedish literature.
The stone was discovered built into the wall of the church in the 19th century and removed from the church wall a few decades later. The church was built in the 12th century, and it was common to use rune stones as building material for churches. The stone was probably carved in the early 9th century, judging from the main runic alphabet used ("short-twig" runes) and the form of the language. It is covered with runes on five sides, all except the base part that was to be put under ground. A few parts of the inscription are damaged, but most of it remains readable.
The name "Rök Stone" is something of a tautology: the stone is named after the village, "Rök", but the village is probably named after the stone, "Rauk" or "Rök" meaning "skittle-shaped stack/stone" in Old Norse.
The stone is unique in a number of ways. It contains a fragment of what is believed to be a lost piece of Norse mythology. It also makes a historical reference to Ostrogothic king (effectively emperor of the western Roman empire) Theodoric the Great. It contains the longest extant pre-Christian runic inscription - around 760 characters, and it is a virtuoso display of the carver's mastery of runic expression.
The inscription is partially encrypted in two ways; by displacement and by using special cipher runes. The inscription is intentionally challenging to read, using kennings in the manner of Old Norse skaldic poetry, and demonstrating the carver's command of different alphabets and writing styles (including code). The obscurity may perhaps even be part of a magic ritual.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
