The Karlevi Runestone, designated as Öl 1 by Rundata, is commonly dated to the late 10th century. It is one of the most notable and prominent runestones and constitutes the oldest record of a stanza of skaldic verse.
The runic inscription on the Karlevi Runestone is partly in prose, partly in verse. It is the only example of a complete scaldic stanza preserved on a runestone and is composed in the "lordly meter" the dróttkvætt. It is notable for mentioning Thor's daughter Þrúðr and Viðurr, one of the names for Odin, in kennings for "chieftain." In the second half of the stanza a reference is made to Denmark, but it is not clear what exactly this means in this poetic context.
The stone is contemporary with the Battle of the Fýrisvellir and it is consequently possible that the stone was raised by warriors who partook in it, in memory of their lord. The inscription, which is on a granite stone that is 1.4 meters in height, is classified as being in runestone style RAK. This is the classification with inscriptions with runic text in bands that have no attached dragon or serpent heads and the ends of the runic bands are straight. The non-runic inscription on the reverse side appears to be accompanied by a small Christian cross and a Norse pagan Thor's hammer, or Mjöllnir.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
