I petitioned the exalted Deity, and he heard my prayer. And the exalted Deity commanded the two mountains and they moved and approached each other to a distance of twelve ells, and there I made ... copper gates 12 ells broad, and 60 ells high, and smeared them over within and without with copper ... so that neither fire nor iron, nor any other means should be able to loosen the copper; ... Within these gates, I made another construction of stones ... And having done this I finished the construction by putting mixed tin and lead over the stones, and smearing ... over the whole, so that no one might be able to do anything against the gates. I called them the Caspian Gates. Twenty and two Kings did I shut up therein.
