The historian Herodotus (484 – ca. 425 BCE), and the scholar Callimachus of Cyrene (ca. 305 – 240 BCE) at the Museum of Alexandria, made early lists of seven wonders but their writings have not survived, except as references. The seven wonders included:
* Great Pyramid of Giza
* Hanging Gardens of Babylon
* Statue of Zeus at Olympia
* Temple of Artemis at Ephesus
* Mausoleum of Maussollos at Halicarnassus
* Colossus of Rhodes
* Lighthouse of Alexandria
The earliest lists had the Ishtar Gate as the seventh wonder of the world instead of the Lighthouse of Alexandria.
The list known today was compiled in the Middle Ages—by which time many of the sites were no longer in existence. Today, the only ancient world wonder that still exists is the Great Pyramid of Giza.
