The Pearl of the Eastern Merchants

"My glorious robe they took off me which in their love they had wrought me and my purple mantle which was woven to match my stature. And with me they made a compact. If thou goest down into Egypt and thence bringest the one pearl, the pearl that lies in the sea, hard by the loud breathing serpent, then shalt thy put on thy robe and thy mantle that goeth upon it," he said. "And with our brother our second shalt thou be heir in our kingdom."
