Lungs and Windpipe Sema Amulet

The Sema or Sma hieroglyph, used in the words “unification,” “to unite,” and their derivatives, represents an animal’s lungs and windpipe. It is often described as a pair of lungs attached to a windpipe, genitalia, and sometimes both simultaneously.

The Sema was often placed on a mummy’s chest in order to give it life in the underworld. As such, the shape of this sign frequently appears in Egyptian art in scenes of the king uniting the two lands of Upper and Lower Egypt.

As an amulet, the sema hieroglyph ensured a unified corpse, integral to one’s survival in the afterlife. The customary choice of dark stone for this amulet refers to the darkness of the night sky and the fertile silt of the Nile’s inundation (or annual flooding)—the sources of the daily rebirth of the sun and the yearly regeneration of nature.
