Seven seems to be a magical number in many cultures, and is often imbued with mystical and religious attributes. In the Abrahamic faiths, for instance, it is believed that God created the world in seven days, whilst in Greek mythology, the Pleiades were seven sisters who were the companions of the goddess Artemis. Other groups of seven include the Seven Wonders of the World, the Seven Sages of Greece and the Shichi Fukujin (Seven Gods of Fortune) of Japanese mythology. In folklore, seven also has a special role in the order of birth.
