"Ameth"
is Hebrew for "truth." The Sigil of Ameth (or Sigillum
Dei Aemeth) is best known as the large, complex circular symbol, with six
pointed figures and the names of God and various angels incribed thereon.
It is best known in relation to the Enochian workings of Dr. John Dee, as
he was instructed to re-create it by angels he contacted during his scrying
sessions with Edward Kelly. (The sigil predates Dee, having first appeared
in a thirteenth century grimoire; it was later expanded upon by Athanasius
Kircher.)
The
disk was placed in several places on the Holy
Table- beneath Kelly's
scrying stone and under each leg. The
sigil would then protect the workings from outside influences.
