The Pentagram :

The symbol of the five pointed star is one of the most ancient written symbols. The Pentagram is a protective sign connected with the harmony of Venus.

Pentagrams were used symbolically in ancient Greece and Babylonia, and are used today as a symbol of faith by many Wiccans, in a similar way to the use of the cross by Christians and the Star of David by Jews. Christians once more commonly used the pentagram to represent the five wounds of Jesus, and it also has associations within Freemasonry.

The pattern of Venus's synodic movement in the sky looks like a Rose.
