There is variety in size of runestones, and the Greece examples are no different. One is a carved whetstone (3.3 x 1.8 x 1.3), mentioning two men who traveled to Greece, Jerusalem, Iceland, and Serkland (the name referring to land of Muslims). (This was originally thought to be a forgery; the claim was that a worker found it while digging a shaft for a telephone wire. It was considered authentic partially because of a few misspellings of place names: mistakes a forger would not make when every available document one might use as reference spelled those locations accurately.)
One is a boulder 59 feet in circumference, known as U 112, side A of which is shown here. It reads:
Ragnvaldr had the runes carved in memory of Fastvé, his mother, Ónæmr's daughter, (who) died in Eið. May God help her spirit.
Side B reads:
Ragnvaldr had the runes carved; (he) was in Greece, was commander of the retinue.
U 112 is an example of how the runestones are valuable to modern scholars and historians as far more than an example of art. The name Ragnvaldr indicates that was likely a member of a noble family. The reference to his mother and her father are useful in connecting Ragnvaldr to his family. Ónæmr is mentioned on two other runestones, through which we know that Ragnvaldr had two aunts and a cousin who received Danegeld three times. Ragnvaldr was part of a wealthy family. Also, "commander of the retinue" makes him captain of the Varangian Guard, and well-paid in his own right.
The link between Scandinavia and the Byzantine Empire lasted a long time, especially because of the Varangian Guard, and even motivated Norway and Sweden to create laws specifically about those who went south, especially regarding inheritance. I'll talk about this north-south connection, the Varangian Guard, and keeping family wealth in the country next time.
