This is the Rök Runestone in Östergötland, Sweden. The runes used are the short-twig runes written in an Old Norse dialect, as well as kennings and cipher runes, and is covered by runes on all 5 sides (approximately 760 characters). This is the modern English translation:
In memory of Vémóðr/Vámóðr stand these runes.
And Varinn coloured them, the father,
in memory of his dead son.
I say the folktale / to the young men, which the two war-booties were, which twelve times were taken as war-booty, both together from various men.
I say this second, who nine generations ago lost his life with the Hreidgoths; and died with them for his guilt.
Þjóðríkr the bold,
chief of sea-warriors,
ruled over the shores of the Hreiðsea.
Now he sits armed
on his Goth(ic horse),
his shield strapped,
the prince of the Mærings.
I say this the twelfth, where the horse of Gunnr sees fodder on the battlefield, where twenty kings lie.
This I say as thirteenth, which twenty kings sat on Sjólund for four winters, of four names, born of four brothers: five Valkis, sons of Hráðulfr, five Hreiðulfrs, sons of Rugulfr, five Háisl, sons of Hôrðr, five Gunnmundrs/Kynmundrs, sons of Bjôrn.
Now I say the tales in full. Someone …
I say the folktale / to the young men, which of the line of Ingold was repaid by a wife’s sacrifice.
I say the folktale / to the young men, to whom is born a relative, to a valiant man. It is Vélinn. He could crush a giant. It is Vélinn … [Nit]
I say the folktale / to the young men: Þórr. Sibbi of Vé, nonagenarian, begot (a son).
