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.
The Pharos ( Lighthouse) of Alexandria
The Pharos at Alexandria was a lighthouse at the port of the Egyptian city named for Alexander the Great. It was completed around 300-200 B.C., a skyscraper of the ancient world standing 600 feet high. The summit was an open place, surrounded by bronze columns, where a fire burned at night, fed by wood raised thru the central shaft.
The most legendary feature of the Lighthouse of Alexandria was a gigantic mirror which either reflected the sun's rays or the fire by night - up to 150 miles out at sea. Erected in the reign of Ptolemy II Philadelphus on an inlet off the harbor of Alexandria, this lighthouse was the prototype of all similar structures built along the coasts of the Roman Empire. The magnificent edifice was destroyed more than a millennium later by a series of earthquakes.
The Lighthouse of Alexandria was dedicated to the planet Saturn.
