From an original painting by Marius Michael-George

In the Jewish mystical tradition of Kabala, Metatron is considered the highest
of the archangels corresponding to Keter and positioned in the crown of the
Tree of Life.
Because of this position he is also known as the Angel of the Presence.
It is believed that he brought to the Jewish mystics the teachings of Kabala as
well as the science of Creation through Sacred Geometry (see our image of
the Metatron Matrix)
In the Talmud and Targum Metatron is the Angel of the Covenant, a direct
link between God and humanity.
