[Rightwing Canuck]

One Ring to rule them all,
One Ring to find them,
One Ring to bring them all,
And in the darkness bind them

[John Locke]

When Theseus and his companions landed at Crete, Minos was there to welcome them. He asked each who they were.

When it came to Theseus' turn he said, "I am Theseus, prince of Athens, son of Poseidon!"

To this Minos replied, "If you were the prince of Athens wouldn't old Aegeus be your father. To prove you are son of Poseidon fetch my ring."

Minos threw his ring into the sea. Praying to Poseidon Theseus dived into the water. He saw the nymph Thetis who gave him the ring and an old crown. Theseus came to the surface holding the ring and the crown.
