Throughout history many people have constructed lists to document mankind's outstanding accomplishments.  The first person to create such a list was a Greek poet named Antipater.  Antipater was followed by others such as the Greek engineer and mathematician Philon of Byzantium.   It is not surprising that most of the wonders listed were examples of Greek culture, though only two were located in present day Greece, three others were products of Greek artistry.  Naturally, there was disagreement about what should comprise the list.  Most agreed on six:  The Great Pyramids of Egypt, The Hanging Gardens of Babylon, The Statue of Zeus at Olympia, The Temple of Artemis at Ephesus, The Mausoleum of Halicarnassus, and The Colosus of Rhodes.  After great debates, and a considerable amount of time, the final list consisted of the six mentioned above and The Lighthouse of Alexandria.  The Seven Wonders of the Ancient World never existed simultaneously, and only The Great Pyramids still exist today.
