Ægishjálmur – The Helm of Awe.
Ægishjálmur (pronounced aye-yiss-hchyawl-mer) etymologically means the Helm of Ægir. Ægir is an Old Norse word meaning terror. It is also the name of a destructive giant associated with the sea. It is now usually defined as Helm of Awe and reference to it occurs often in the Poetic Edda, a part of the Icelandic medieval Codex Regius (Royal Manuscript).
The power of an
Ægishjálmur could be invoked through the use of a special kind of magic called Seiðr (a Nordic Wizardry practiced well before the advent of Vikings). Seiðr could be used to affect the mind with forgetfulness, delusion, illusion, or fear. The
Ægishjálmur is a special subset of Seiðr Magic called Sjónhverfing, the magical delusion or deceiving of the sight where the Seið-Witch affects the minds of others so that they cannot see things as they truly are.
Some suggest the center circle most likely represents one’s Self surrounded by protective Energy. Crowfoot describes all Ægishjálmar as having three zones: an outer ring (for the subjective Universe), a middle range (the objective Universe) and a centre region (the Inner Being). They all represent the basic cosmological blueprint of the Yggdrasil with nine Worlds. This is especially true of the eight-spoke wheel sigils. Each spoke is one of the eight worlds that lie to the north, south, east, west and upper and lower worlds. The ninth world is in the center where all the spokes come together (Midgard).
