Thurisaz
The rune is called Thurs in the Icelandic and Norwegian rune poems. In the Anglo-Saxon [rune poem] it is called thorn, whence the name of the letter þ derived.
It is transliterated as þ, and has the sound value of a voiceless dental fricative .
The rune is absent from the earliest Vimose inscriptions, but it is found in the Thorsberg chape inscription, dated to ca. AD 200.
The rune may have been an original innovation, or it may have been adapted from the classical Latin alphabet's D, or from the Rhaetic alphabet's Θ.
Name
In Anglo-Saxon England, the same rune was called Thorn or "Þorn" and it survives as the Icelandic letter Þ (þ). An attempt has been made to account for the substitution of names by taking "thorn" to be a kenning for "giant".It is disputed as to whether a distinct system of Gothic runes ever existed, but it is clear that most of the names of the letters of the Gothic alphabet correspond to those of the Elder Futhark. The name of ?, the Gothic letter corresponding to Þ, is an exception: it is recorded as thyth in the Codex Vindobonensis 795, which has been interpreted as the Gothic word þiuþ " good", and as such unrelated to either þurs or þorn.
The lack of agreement between the various glyphs and their names in Gothic, Anglo-Saxon, and Old Norse makes it difficult to reconstruct the Elder Futhark rune's Proto-Germanic name.
Assuming that the Scandinavian name þurs is the most plausible reflex of the Elder Futhark name, a Common Germanic form þurisaz can be reconstructed.
