The Trojan woman Briseis had became a prize and slave to Achilles. Achilles had sacked the hometown of Briseis and captured her. He took her into the Greek camp along with other prize slaves and Agamemnon had chosen Cressida as his slave. But Agamemnon was to give Cressida back to the Trojans after her father had ransomed her.  Agamemnon in his anger had retaliated by taking Achilles's slave Briseis into his tent.  This had angered Achilles to the point of refusing to fight for the Greeks any longer.  This action caused the death of Patroclus the best friend of Achilles.

A picture of her follows:

Briseis, Slave of Achilles

The beauty of Briseis was very important to her, and probably saved her life, but it also made her the slave of Achilles. Though Achilles thought of Briseis as a valuable possession, in fact she was not an object that he possessed without trouble. When the gods denied Agamemnon his slave, Cressida, he demanded Breseis of Achilles. This caused Achilles to pout insufferably and remove himself from battle. The result was that the forces of Agamemnon began to lose ground. It was only the death of Patroclus that caused the great king, Agamemnon, to relent and give Briseis back. Briseis was not only slave, but a pawn between these powerful men. Her beauty made her a valuable possession but one that others coveted. This caused a great commotion that was not productive. The moral may be interpreted as beautiful women get men into trouble, but it is more properly that greed causes suffering to men and women.
