The Hamsa
The Hamsa is a talisman in shape of a hand used against the evil eye. It is worn very often in form of jewelry or amulets. Hamsa means five in hebrew and arabic. It is also called the Hand of Miriam, in reference to the sister of Moses and Aaron. It is a kind of "protecting hand" or "hand of God".
There is an association to the 5 books of Torah because of the 5 fingers. Sometimes they are inscribed with Hebrew prayers.
