Chapter I
What it means
The hamsa is a hand that stops harm. Its main purpose is to turn away the evil eye, the envious look believed in many Mediterranean and Middle Eastern cultures to bring misfortune. The eye often drawn in its palm looks back at the evil eye and disarms it.
Jews have linked its five fingers with the five books of the Torah, and some Muslims with the five pillars of Islam. Such readings are popular rather than official; at heart it is a sign of protection and blessing.
Chapter II
Where it comes from
Hand amulets are very old in the region; their exact origins are debated. The hamsa became especially popular in North Africa, among Muslim and Jewish communities alike, and in Spain under Muslim rule. Sephardi and Mizrahi Jews carried the custom across the world.
Chapter III
Where you see it today
Hamsas hang over doorways and in cars, are painted on walls and are worn as jewellery throughout North Africa, the Middle East and Israel. They are common gifts for a new home or a newborn child.
