This is the western (left-hand) corner of the second range of the Casa Grande at Sayil. The double columns and trapezoidal doorways echo those on the first level (now mostly fallen) west of the central stairway. The banded split columns on the facade are a common motif in the architecture of the Puuc hills.

 This is one of the few engravings which are not entirely accurate. The corner mask differs slightly from that drawn by Catherwood, and the ornamentation over the doorway to the right is drawn out of proportion. Directly over the doorway is a figure of the Descending God, described by Stephens as "a man supporting himself on his hands, with his legs expanded in a curious rather than delicate attitude...." To its left a fish or serpent opens its jaws toward the corner, not to the right as shown in the plate. This is an error of placement, however, rather than of design, since to the right of the diving figure (and not visible in the photograph) is a similar animal whose orientation and marking are identical to the one drawn by Catherwood.

 The upper range of the second story has been extensively repaired, since the split columns and cornice moldings had almost entirely fallen by the mid 1930's. The upper zone of the third story has also undergone similar restoration.
