A search for Tlaloc turns up this sculpture which now stands outside the Mexico City Museum of Anthropology. So named source of life because it is the deity of water. No water, no life.
I'm reminded by this card water is the first thing looked for on other planets. We can cover ourselves and create artificial sun in enclosed communities, but without a source of water from sky or earth the exercise is pointless, regardless of how many billions gets thrown at it. Closer to home, we are upside down in our priorities; we carpet deserts with golf courses and green lawns, yet worry about running out of oil. In 2000 years some new civilization will shake their heads at our shortsightedness.
"In an age when man has forgotten his origins and is blind even to his most essential needs for survival, water along with other resources has become the victim of his indifference." ~ Rachel Carson 1907-1964
