"The whole long facade was ornamented with sculptured stone, of which,
large as the engraving is, the details cannot appear; but, to give some
idea of their character, a detached portion is represented in Plate IX, and,
I ought at the same time to remark, is perhaps the most curious and
interesting of any. It is at the left end of the principal building, and in the
angle of the corner are the huge open jaws of an alligator, or some other
hideous animal, enclosing a human head."
(Stephens, vol. 2, p. 36)
