In the fall of 1994 a team of archaeological scuba divers entered the waters off of Alexandria, Egypt. Working beneath the surface they searched the bottom of the sea for artifacts. Large underwater blocks of stone were marked with floating masts so that an Electronic Distance Measurement station on shore could obtain their exact positions. Pharos Lighthouse stood on the eastern point of Pharos Island some distance from the city center of Alexandria. Constructed at the beginning of the third century BC over a period of about twelve years and at an enormous cost and using considerable slave labor, Pharos Lighthouse was completed and inaugurated by the first Ptolemy's son, Ptolemy Philadelphia, in 283 (some say 279 BC, when Ptolemy Philadelphia held a festival to honor his parents). Prior to its destruction, it underwent a number of modifications by later rulers. The architect was Sostratos, a Greek from the Asia Minor city of Cnidus, whose name also appears on the sanctuary of Appolo at Delphi and on Delos. Though only the king's name was allowed on buildings erected during their reigns in the period, Sostratos got around this by also carving his own with a dedication, which was then covered with plaster. The lighthouse was apparently a tourist attraction from the very beginning. We are told that food was sold to visitors at the observation platform at the top of the first level. A smaller balcony provided a view from the top of the eight-sided tower for those that wanted to make the additional climb. The view from there must have been impressive as it was probably 300 feet above the sea. There were few places in the ancient world where a person could ascend a man-made tower to get such a perspective.
