Lighthouse of Alexandria
Pharos was a small island just off the coast of Alexandria. It was linked to the mainland by a man-made connection named the Heptastadion, which thus formed one side of the city's harbor. As the Egyptian coast is very flat and lacking in the kind of landmark used at the time for navigation, a marker of some sort at the mouth of the harbour was deemed necessary - a function the Pharos was initially designed to serve. Use of the building as a lighthouse, with a fire and reflective mirrors at the top, is thought to date to around the 1st century AD, during the Roman period. Prior to that time the Pharos served solely as a navigational landmark.
The medieval Chinese were familiar with the story of the lighthouse in Alexandria by at least the Song Dynasty (960 - 1279) period. In his book Zhu Fan Zhi, Zhao Ru-gua wrote in 1225 of a minaret lighthouse in Alexandria, Egypt, perhaps the ancient Lighthouse of Alexandria (Wade-Giles spelling):
The country of O-Ken-Tho (Alexandria) belongs to Egypt (Wu-Ssu-Li). According to tradition, in olden times a stranger (i jen), Chhu-Ko-Ni by name, built on the shore of the sea a great pagoda, underneath which the earth was excavated to make two rooms, well connected and thoroughly hidden. In one vault was stored grain, and in the other arms. The tower was 200 ft. high [Note: chang = 10 feet, chhih = 1 foot]. Four horses abreast could ascend (by a winding ramp) to two-thirds of its height. Below the tower, in the middle, there was a well of great size connected by a tunnel with the great river. To protect this pagoda from foreign soldiers, the whole country guarded it against all enemies. In the upper and lower parts of it twenty thousand men could readily be stationed as a guard or to make sorties. At the summit there was an immense mirror. There was an old story said that if warships of other countries tried to make an attack, the mirror detected them beforehand, and the troops were ready to repel it. But in recent years there came (to Alexandria) a foreigner, who asked to be given work in the guardhouse below the tower, and he was employed to sprinkle and to sweep. For years no one entertained any suspicion of him, but suddenly one day he found an opportunity to steal the mirror and throw it into the sea, after which he made off
