Who proposed that water is made up of four elements?

Question

The four elements there are earth,water,fire and air.

Answer 1

Not just water, but everything was supposed to be made of those four elements. Aristotle was one of the main people proposing such a view, but the whole structure evolved over time, so it is a bit hard to pinpoint just one person.

Answer 2

According to the Empedocles, a Greek philosopher, scientist and healer who lived in Sicily in the fifth century B.C., all matter is comprised of four "roots" or elements of earth, air, fire and water. Fire and air are outwardly reaching elements, reaching up and out, whereas earth and water turn inward and downward.
In his Tetrasomia, or Doctrine of the Four Elements, Empedocles described these elements not only as physical manifestations or material substances, but also as spiritual essences. He associated these elements with four gods and goddesses - air with Zeus, earth with Hera, fire with Hades, and water with Nestis (believed to be Persephone):

Answer 3

The idea was NOT that water was composed of the four elements, but that all of nature was. Empedoclese was the the Greek philosopher who developed the idea.
