The Christian image of fish silver medaillon komboskini bracelet in red.
 
Apart from the cross, the fish symbol is probably the most recognizable symbol of faith. 
 
During the early days of Christianity, Christians were often put to death for practicing their faith, so they worshiped in secret places. A fish painted or etched on the outside door of a house let other Christians know that they would be safe and welcome inside. The ancient catacombs in Rome are filled with images of fish, carved there by Christians hiding from persecution.
