The work around the form and meaning of water has always fascinated philosophers, scientists and writers. For Thales, a Greek philosopher who lived five centuries before Christ, water is what underlies all things, what holds them together. According to the Five Elements theory of Traditional Chinese Medicine, water is expressed as the feminine cosmic principle, the soul of the world, the mother par excellence, the mother of life. Archimedes, observing a body immersed in water, developed the famous principle behind hydrostatic thrust. Andrea Camilleri gives the title to one of his novels, La forma dell'acqua (The Shape of Water), and on this principle he makes the protagonists converse: "What is the shape of water?". "But water has no shape!" I said laughing: "It takes the shape it is given").
