you don't seem to list" truth lives at the bottom of a well". is its origin known?
An australian fish was called Veritas by gilbert whiteley because it was discovered in a well.

Brewer's Dictionary of Phrase & Fable says that "this expression has been attributed to Heraclitus, Cleanthes, Democritus the Derider, and others". (VSD)
