Mural: "Subterranean Forces" (1926-1927), which is on the right wall of the chapel at the Universidad Autónoma de Chapingo.
Comments: Here we see three muscular female nudes emerging from volcanic magma at the earth's core. On either side of the central figure are real circular windows in the chapel wall. The muralist may have used these two architectural features as part of the "idea" of the mural; or, then again, he may not have; whether he intended them to be part of the mural's theme is irrelevant to the fact that, in fact, they are there. The complex images on the extreme far left and the one below the central nude (back turned to the viewer) represent the golden crystals hidden in the depths of the earth. (Unfortunately, the professor-photographer cut off a few inches on the right side of this mural, just enough to that side that would (or does) actually complete the window on the right including the toes of the nude on the bottom right corner of the mural.)
Humanities Questions: (A) Since the entire right wall is dedicated to the theme of Canción a la Tierra (song to the earth), how does this mural evoke both "song" and "earth" in the context of universal themes of Latin American humanities? (B) Compare and contrast this mural to "Marabá", Rodolfo Amoêdo's 1882 Brazilian painting:
