Þurs

Thurs is one of the runes where the Norwegian and Icelandic poems agree closely on subject even while developing it in their own separate idioms: both read the rune as the giant, a being of torment and misfortune rather than a neutral or admired figure, the Norwegian poem naming the giant as a cause of anguish to women and a source of the kind of misfortune that leaves few men cheerful, and the Icelandic poem developing the same essential reading further, calling the giant torturer of women and a dweller among the cliffs, imagery that fits the giants' place in the wider Old Norse mythological record as beings belonging to wild, uncultivated land outside the settled human and divine order the gods of Asgard maintain. This continuity of reading across two poems separated by roughly two centuries suggests thurs carried an unusually stable, negative association throughout the Younger Futhark's working life, in contrast to a rune such as Ur, where the two witnesses genuinely part ways.

Dickins' 1915 edition notes that thurs's reading here is broadly consistent with its Elder Futhark cognate Thurisaz and, further, with the Old English Thorn stanza's own move from giant to a merely sharp plant, three related traditions all keeping some trace of hazard attached to the same rune shape even as the specific danger named shifts between them.

Thurs is the third of the sixteen Younger Futhark runes, descending from Thurisaz, the Elder Futhark's own third rune, one of the more stable continuities across the sixteen rune reduction, its name, sound value and core association with a supernatural hazard all carried forward largely unchanged even as many of the row's other signs absorbed additional sounds or shifted meaning considerably further.

Barnes' handbook notes Thurs's consonant value th as one of several sounds the sixteen rune row kept clearly distinguished despite its general economy elsewhere, a th sound genuinely load bearing in Old Norse and evidently important enough to preserve its own dedicated sign through the reduction rather than being folded into a neighbouring rune's coverage the way some of the row's vowels and voiced or unvoiced consonant pairs were. The rune's letterform, a simple thorn shaped stroke, is essentially identical across the Elder Futhark, the futhorc and the Younger Futhark, one of the row's most visually stable signs across all three surviving runic traditions. Barnes notes that thurs also carried a documented secondary use in Viking age magical and protective inscriptions, sometimes carved repeatedly as an aggressive or apotropaic mark, a practical application the rune poems themselves do not describe but which surviving inscribed objects independently attest.
