From Greek mythology and the Labours of Heracles, the entrance to the Underworld at the lake of Lerna was guarded by the dreaded, giant, many headed water serpent Hydra. A large triple serpent in symmetrical form made of antiqued and polished pewter and with red Swarovski crystal eyes, on a double, black braided cord necklace with pewter end caps, connected by a lobster claw fastener.
