Then in 353 B.C. Mausolus died, leaving his queen Artemisia, who was also his sister, broken-hearted (It was the custom in Caria for rulers to marry their own sisters). As a tribute to him, she decided to build him the most splendid tomb in the known world. It became a structure so famous that Mausolus's name is now associated with all stately tombs throughout the world through the word mausoleum. The building, rich with statuary and carvings in relief, was so beautiful and unique it became one of the Seven Wonders of the Ancient World.
