ces, the spaces
between them being covered with carved ornaments. There is but one room
in it. One of the most picturesque ruins at Chichen-Itza is circular in
form, and stands on the upper level of a double-terraced platform. It is
22 feet in diameter, and has four doors, which face the cardinal points.
Above the cornice it slopes gradually almost to a point, and the top is
about 60 feet above the ground. The grand staircase of 20 steps, leading
up to this building, is 45 feet wide, and has a sort of balustrade
formed of the entwined bodies of huge serpents. At some distance from
this is the ruined structure known as the "Casa Colorada," or Red House.
This is shown in Figure 42.

It is 43 feet long by 23 deep, and stands on a platform 62 feet long by
55 wide. It was ornamented above the cornice, but the decorations are
much defaced by decay. A stone tablet extending the whole length of the
back wall, inside, is covered by an inscription.

A remarkable structure is found at this place, which Mr. Stephens called
the "Gymnasium, or Tennis Court." It consists of two immense parallel
walls 274 feet long, 30 thick, and 120 apart. On elevations facing the
two ends of the open space between them, 100 feet from the ends of the
walls, stand two edifices much ruined, but showing, in their remains,
that they were richly ornamented. Midway in the length of the walls,
facing each other, and 20 feet above the ground, are two massive stone
rings or circles 4 feet in diameter, each having in the centre a hole 1
foot and 7 inches in diameter. On the borders around these holes two
entwined serpents are sculptured, as seen in Figure 43.

There was a similar structure in the old city of Mexico, and remains of
one like it are found at Mayapan. They were, probably, used for games of
some kind. Among the other ruins at Chichen-Itza are the remains of a
lofty edifice which has two high ranges or stories. On the outside the
ornamentation is simple and tasteful, but the walls of its chambers are
very elaborately decorated, mostly with sculptured designs, which seem
to have been painted. In one of the upper rooms Mr. Stephens found a
beam of sapote wood used as a lintel, which was covered with very
elegantly carved decorations. The walls of this room were covered, from
the bottom to the top of the arched ceiling, with painted designs
similar to those seen in the Mexican "picture writing." Decay had
