The concept of seven outstanding and amazing achievements in building and sculpture was being put forward by the time of Strabo - a Greek historian and geographer who lived from about 64 BC to AD 21.
The list includes the Pyramids of Egypt, the Hanging Gardens of Babylon, the gold and ivory statue of Zeus at Olympia created by Pheidias (a leading Athenian sculptor of the 5th century BC) and the Temple of Artemis at Ephesus (built under King Croesus of Lydia in the 6th century BC).
The remaining Wonders were the Mausoleum at Halicarnassus (the Ionic white marble tomb of King Mausolus designed by the architect Pythius and built by the king's sister and wife Artemisia around 350 BC), the Colossus of Helos at Rhodes (built around 300 BC and destroyed by an earthquake in 227 BC) and the great Pharos lighthouse at Alexandria in Egypt.
Only one of these 'wonders' still survives intact and not ruined - the Pyramids of Egypt.
