divine name · from c. 1200
AGLA
An acronym, not a word: Atah Gibor Le-olam Adonai, 'Thou art mighty forever, Lord', compressed to four letters and written on almost everything.
What the sources claim for it
A compressed declaration of divine power, used as a name of God.
What is it made of?
A notariqon: one letter taken from each word of a Hebrew sentence, Atah Gibor Le-olam Adonai, and read afterwards as though it were a name in its own right.

History
Where does AGLA come from?
AGLA is a notariqon, a name built from the initial letters of a phrase, and the phrase is a line of Jewish liturgy. Once compressed it circulates as a name in its own right through Latin magical manuscripts, on amulets, on rings, on church bells, and on the quarters of the Solomonic circle.
It shows how the operative tradition treats language. A sentence in Hebrew liturgy becomes a four-letter token; the token is copied by scribes who cannot expand it; and by the early modern period AGLA is listed alongside genuine divine names as though it were one — which, within that tradition, it now effectively is.
The larger argument
Why is it in a corpus about spirits?
AGLA is what transmission looks like when it works and nobody notices. A line of Jewish liturgy is compressed to four letters, the four letters are copied by Latin scribes who cannot expand them, and within a few centuries AGLA is written on circles and church bells beside genuine divine names as if it were one. The same process, run on spirit names rather than divine ones, is how a Canaanite title ends up as a demon in a seventeenth-century list.
Afterwards
What did it turn into?
Survives on medieval bells and rings across Europe, and in every printed grimoire that copies the Solomonic circle.
Which texts describe it?
Oldest first, with what each one does with the mark. A mark described in a Bronze Age incantation and a mark first drawn in a seventeenth-century manuscript are different kinds of claim, whatever the shape has in common.
