2. Were the Hanging Gardens of Babylon real?
Ancient writers describe a fantastic series of gardens constructed at the ancient city of Babylonin modern-day Iraq. It’s not clear when these gardens were built, but some ancient writers were so impressed by the gardens that they called them a “wonder of the world.” Around 250 B.C., Philo of Byzantium wrote that the Hanging Gardens had “plants cultivated at a height above ground level, and the roots of the trees are embedded in an upper terrace rather than in the earth.”
So far, archaeologists who have excavated Babylon have been unable to find the remains of a garden that meets this description. This has left archaeologists with a question: Did the hanging gardens really exist? In 2013, Stephanie Dalley, a researcher at the University of Oxford, proposed in a book that the gardens were actually located at the Assyrian city of Nineveh. Over the past two decades, both Babylon and Nineveh have suffered damage from wars and looting, and it seems unlikely that this mystery will ever be fully solved.
3. Is there a City of Atlantis?
Writing in the fourth century B.C., the Greek philosopher Plato told a story of a land named Atlantisthat existed in the Atlantic Ocean and supposedly conquered much of Europe and Africa in prehistoric times. In the story, the prehistoric Athenians strike back against Atlantis in a conflict that ends with Atlantis vanishing beneath the waves.
