During the 6th and 7th centuries, the initial
j in *
jāra was lost in
Proto-Norse, which also changed the sound value of the rune from /j/ to an /a/ phoneme. The rune was then written as a vertical staff with a horizontal stroke in the centre, usually transliterated as
A, with majuscule, to distinguish it from the ansuz rune,
a. During the last phase of the Elder Futhark, the
jēra-rune came to be written as a vertical staff with two slanting strokes in the form of an X in its centre (). As the form of the rune had changed considerably, an older 7th century form of the rune () was assumed by the
s-rune. When the
n-rune had stabilized in its form during the 6th and 7th centuries, its vertical stroke slanted towards the right (), which made it possible to simplify the
jēra-rune by having only one vertical stroke that slanted towards the left, giving the
ár-rune of the classic Younger Futhark (note however, that the earliest YF inscriptions, such as the
Ribe skull fragment, still retain the earlier X-shape). Since a simpler form of the rune was taken by the /a/ phoneme, the older cross form of the rune now came to be used for the /h/ phoneme. The development of the Jēran rune from the earliest open form was not known before the discovery of the
Kylver Stone in 1903, which has an entire
elder futhark inscription on it. Therefore, the interpretation of the
golden horns of Gallehus was slightly wrong before 1903, as it was believed this rune form could be an early form of the
Ingwaz rune. The second word on the horns was thus interpreted as
holtingaz rather than
holtijaz. ==See also==
