ever been
found to have existed between the monuments and civilizations of the
inhabitants of this continent and those of the old world_. On what
ground they hazard such an opinion it is difficult to surmise, since to
my knowledge the ancient ruined cities of Yucatan, until lately, have
never been thoroughly, much less scientifically, explored. The same is
true of the other monumental ruins of the whole of Central America.

When Mrs. Le Plongeon and myself landed at Progresso, in 1873, we
thought that because we had read the works of Stephens, Waldeck,
Norman, Fredeichstal; carefully examined the few photographic views made
by Mr. Charnay of some of the monuments, we knew all about them. Alas!
vain presumption! When in presence of the antique shrines and palaces of
the Mayas, we soon saw how mistaken we had been; how little those
writers had seen of the monuments they had pretended to describe: that
the work of studying them systematically was not even begun; and that
many years of close observation and patient labor would be necessary in
order to dispel the mysteries which hang over them, and to discover the
hidden meaning of their ornaments and inscriptions. To this difficult
task we resolved to dedicate our time, and to concentrate our efforts to
find a solution, if possible, to the enigma.

We began our work by taking photographs of all the monuments in their
_tout ensemble_, and in all their details, as much as practicable. Next,
we surveyed them carefully; made accurate plans of them in order to be
able to comprehend by the disposition of their different parts, for what
possible use they were erected; taking, as a starting point, that the
human mind and human inclinations and wants are the same in all times,
in all countries, in all races when civilized and cultured. We next
carefully examined what connection the ornaments bore to each other, and
tried to understand the meaning of the designs. At first the maze of
these designs seemed a very difficult riddle to solve. Yet, we believed
that if a human intelligence had devised it, another human intelligence
would certainly be able to unravel it. It was not, however, until we had
nearly completed the tracing and study of the mural paintings, still
extant in the funeral chamber of Chaacmol, or room built on the top of
the eastern wall of the gymnasium at Chichen-Itza, at its southern end,
that Stephens mistook for a shrine dedicated to the god of the players
at ball,
