Runamo

[1] As early as the 12th century, the Danish chronicler Saxo Grammaticus reported in the introduction to his Gesta Danorum that the runic inscription was no longer legible, being too worn down.

This had been established by a delegation sent by the Danish king Valdemar I of Denmark (1131–1182) to read the inscription: Now in Bleking is to be seen a rock which travellers can visit, dotted with letters in a strange character.

For there stretches from the southern sea into the desert of Vaarnsland a road of rock, contained between two lines a little way apart and very prolonged, between which is visible in the midst a level space, graven all over with characters made to be read.

Now Waldemar, well-starred son of holy Canute, marvelled at these, and desired to know their purport, and sent men to go along the rock and gather with close search the series of the characters that were to be seen there; they were then to denote them with certain marks, using letters of similar shape.

[7] Finnur defended his thesis in an extensive publication in 1841, but the Danish archaeologist Jens Jacob Asmussen Worsaae made a third study at the location in 1844, which turned the general scholarly opinion towards Berzelius' theory.

The Icelandic archaeologist and scholar Finnur Magnússon claimed to have deciphered the inscription.
Swedish chemist Jöns Jakob Berzelius claimed that the inscription was only natural cracks in the rock.
