102 HISTORICAL TALES. Amasis accordingly wrote a warning letter to his friend. The great prosperity of his friend and ally, he said, caused him foreboding instead of joy, for he knew that the gods were envious, and he desired for those he loved alternate good and ill fortune. He had never heard of any one who was successful in all his enterprises that did not meet with calamity in the end. He therefore counselled Polycrates to do what the gods had not yet done, and bring some misfortune on himself. His advice was that he should select the treasure he most valued and could least bear to part with, and throw it away so that it should never be seen again. By this voluntary sacri- fice he might avert involuntary loss and suffering. This advice seemed wise to the despot, and he began to consider which of his possessions he could least bear to lose. He settled at length on his signet- ring, an emerald set in gold, which he highly valued. This he determined to throw away where it could never be recovered. So, having one of his fifty- oared vessels manned, he put to sea, and when he had gone a long distance from the coast he took the ring from his finger and, in the presence of all the sailors, tossed it into the waters. This was not done without deep grief to Poly- crates. He valued the ring more highly than ever, now that it lay on the bottom of the sea, irretriev- ably lost to him, as he thought; and he grieved for days thereafter, feeling that he had endured a real misfortune, which he hoped the gods might accept as a compensation for his good luck.
