Isa (ᛁ)
Pronunciation: EE-sah · Latin equivalent: I · Heimdall’s ætt, third rune
Name and meaning
Proto-Germanic īsaz, “ice” — the single upright stroke, simplest of all the staves. Ice in the North was both peril and pavement: it stops the ship and bears the sled. Stillness with two faces.
In the rune poems
Attested in all three (íss). The poems dwell on its deceptive beauty — glittering, glassy, fair to look upon — and its treachery underfoot: the bridge that needs no builder and keeps no promises.
Upright
Stillness, pause, things frozen in place. Not death — preservation. A time to hold position, consolidate, and wait for thaw; clarity comes when the surface stops moving. Also self-containment: the cold that keeps its own counsel.
Merkstave
This rune is one of the nine that cannot reverse: its form reads the same either way up. If your set marks each stone’s bottom (see Casting the Runes: Merkstave and the Marked Stone), it may still fall merkstave, and a shadow reading applies — the same force obstructed, frozen, or turned inward. Otherwise, take it as it lies. Read in shadow: the freeze that outstays its use — stagnation mistaken for safety, a heart iced shut.
