Humanities Comments: The arch (a.b.c.) is the famous Mayan corbel arch, which is not exactly an arch per se, and which latter (that is, an arch per se) pre-Columbian architects did not know how to construct. Rather it is an arch-like structure in which the sides gradually extend inward until they simply meet at the top. In this series of four photos, starting at the top left, the camera's zoom lens progressively focusses in on the north building in the Nuns Quadrangle. In (a) and (b), we are looking through the ball court toward the so-called Nuns Quadrangle.
