18k Gold Ring Hercules Knot.
Herculean amma is the knot that is often found in ancient Greek jewels and declares the lacing of life to death
through the connection that Heracles achieves between the two worlds and of course its dual character as mortal and imortal,as demigod.
The Herculean node was named so conventionally by the node with which Hercules had tied to his neck the Nemean lion that he had killed.
