seven wonders of the worlds are dectated on which based?

Answer 1

Antipater, a Greek author living in the Phoenician port of Sidon, lists in one of his poems the most remarkable creations of mankind. They are seven in number: the pyramids of Egypt; the hanging gardens of Babylon; the walls of Babylon; the statue of Zeus at Olympia; the temple of Artemis at Ephesus; the mausoleum of Halicarnassus; the colossus of Rhodes.

His list is the basis of the Seven Wonders of the World, much repeated ever since. Posterity makes one change. It seems a waste for Babylon to have two of the wonders. By about the 8th century AD the walls of Babylon have dropped out, to be replaced by the lighthouse of Alexandria.
