Part of Diego Rivera’s 1952 mural “Water, origin of life”,
which was painted on the walls and bottom of the Lerma River Supply
System, in Chapultepec Park, in Mexico City. It is an unique underwater
mural painting about which Rivera wrote: “At the bottom of a
large reservoir, I painted varieties of protoplasmic life. These evolve,
on the lower portion of the perpendicular walls, into more complex
forms, culminating in a nude man and woman, the final creations of
the mural." [D.R. © 2003 Banco de México Diego Rivera
