And on the shield was a harbour with a safe haven from the irresistible sea, made of refined tin wrought in a circle, and it seemed to heave with waves. In the middle of it were many dolphins rushing this way and that, fishing: and they seemed to be swimming. Two dolphins of silver were spouting and devouring the mute fishes. And beneath them fishes or bronze were trembling. And on the shore sat a fisherman watching: in his hands he held a casting net for fish, and seemed as if about to cast it forth.
There, too, was the son of rich-haired Danae, the horseman Perseus: his feet did not touch the shield and yet were not far from it -- very marvellous to remark, since he was not supported anywhere; for so did the famous Lame One fashion him of gold with his hands. On his feet he had winged sandals, and his black-sheathed sword was slung across his shoulders by a cross-belt of bronze. He was flying swift as thought. The head of a dreadful monster, the Gorgon, covered the broad of his back, and a bag of silver -- a marvel to see -- contained it: and from the bag bright tassels of gold hung down. Upon the head of the hero lay the dread cap of Hades which had the awful gloom of night. Perseus himself, the son of Danae, was at full stretch, like one who hurries and shudders with horror. And after him rushed the Gorgons, unapproachable and unspeakable, longing to seize him: as they trod upon the pale adamant, the shield rang sharp and clear with a loud clanging.
