The Hanging Gardens of Babylon

Weed Out the Sources

Out of that lot, we have only three supposed eye-witnesses:

1. Herodotus, c.450 BC—who doesn't apparently mention them
2. Ctesias, c.400 BC—who gives a structurally detailed description
3. Clitarchus, c.310-301 BC—who gives a brief and ambiguous description

The remaining descriptions depend on either Ctesias or Clitarchus, as you can verify for yourself by reading them in the pages linked to the menu on the left.

So the methodologically sound thing is to concentrate on the eye witnesses first. They are the main cause of doubt about the gardens' existence so let's see how that works.
