Hoor-par-kraat
From Thelemapedia
Hor-pa-kraat (Horus the Child, GD: Hoor-par-kraat)
Horus, the son of Isis and Osiris, distinguished from Horus the Elder, who was the old patron deity of Upper Egypt; but the worship of the two gods became confused early in Egyptian history and the two essentially merged. Represented as a young boy with a child's sidelock of hair, sucking his finger. The Golden Dawn attributed Silence to him, presumably because the sucking of the finger is suggestive of the common "shhh" gesture.
