Miscegenation
The central panel begins a bit to the left of the first part with the Spanish soldier and a Native woman, the principal creators of miscegenation. Jorge González called this part The Original Couple ("La pareja original"), who walk over layers of coal, in which there are imprisoned, sleeping women, symbolizing the riches of the earth: silver, gold, iron and copper. On the surface of this swarm of bodies and precious stones, sprouts a pregnant woman covered with vines, representing the fertility of the earth. From her surge American corn and Old World wheat, nourishment that sustains the bases of industrialization, technology and science, represented as an intricate steel machine on the upper part of the panel.
At the center of the panel there are several overlapping faces, which symbolize the fusion of the races: the largest in red, represents the American race. Below these faces a life-sized, naked woman has a map of Latin America on her lap. She constitutes the principal subject matter of the mural.
On the woman one can see a capital that symbolizes the Greco-Roman contribution to Latin American culture; and a bit to the left, great blocks of solid rock, which create a great, vertical structure, symbolizing Mesoamerican architecture.
