Snake arm bracelets date back to the Classical period in Greece. They were worn in pairs on the upper arms. This example consists of a plain, flat, coiled gold band, with the head and curled body of the snake forming one end and the curled tail the other. The modeling of the snake's head is quite realistic, as are the carefully chased details of the snake's scales.
