Who discovered quicksand?

There was nobody to "discover" quicksand, and it has been lost in history as to who first wrote about the mysteries of the mud bog. It is found all over the world.

Quicksand is solid ground that's been liquefied, usually by an underground water source. A soupy mix of sand and water, quicksand is usually only a few feet deep. It can be found anywhere that land and water meet, including beaches, marshes, and ponds.
