English: A (so defined) Zoographic Character, said to be an ancient version of the Coptic script according to Athanasius Kircher's 1697 book Turris Babel.

This specific character is said to correspond to the coptic letter Sigma (upperscore), Greek Σ, and/or to the letter Omega, Greek Ω, ω; its mystical meaning is said by Kircher to be the "symbol of the Moon" (Lunae symbolum)

Please be noted that those above are the interpretations given by Kircher himself, and must not be taken as scientific thruths in the modern sense.
