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:
Sirmione castle was built near the end of the 12th century as part of a defensive network surrounding Verona. The castle was maintained and extended first as part of the Veronese protection against their rivals in Milan and later under the control of the Venetian inland empire. The massive fortress is totally surrounded by water and has an inner porch which houses a Roman and Medieval lapidary. From the drawbridge, a staircase leads to the walkways above the walls, providing a marvellous view of the harbour that once sheltered the Scaliger fleet. The doors were fitted with a variety of locking systems, including a drawbridge for horses, carriages and pedestrians, a metal grate and, more recently, double hinged doors. Venice conquered Sirmione in 1405, immediately adopting provisions to render the fortress even more secure, fortifying its outer walls and widening the harbour.
Thanks to its strategical geographical location as a border outpost, Sirmione became a crucial defence and control garrison for the ruling nobles, retaining this function until the 16th century, when its role was taken up by Peschiera del Garda.
