In Hoc Signo ~ In This Sign We Shall Conquer

iN HOC SiGNO ~ iN this sign we shall conquer

In the middle is a circle with the secret initials of “IHS”
that is often interpreted as meaning “Iesus Hominum Salvator”
(“Jesus, Saviour of men” in Latin),
or with the term “In Hoc Signo;”
Latin for “In this sign we shall conquer.”
Above the circle are the seventy-two powers of God
according to the Hebrew Kabbalah.
Below are two trees, that on the left bearing the symbols
of the planets and that on the right,
the signs of the zodiac and the names of the tribes of Israel.
