When Mausolus, king of Caria (in Asia Minor), died in 353 B.C. his widow Queen Artemisia was determined to commemorate him with the costliest possible memorial. She built a great marble tomb at Harlicarnassus. A fine pyramid with steps of marble surmounted the rectangular base and on top of the pyramid was a mighty sculpture of Mausolus driving an eight horse chariot group. The structure, designed by Pythius and adorned by the sculptures of Scopas and Praxiteles was eventually destroyed by an earthquake before the fifteenth century. The Mausoleum of Harlicarnassus was dedicated to the planet Mars.
