The tradition cited adds that but few persons have dared to penetrate the cave of Teutli, and on but one occasion, a herd of sheep having entered it, some peons followed to collect and bring them out—a thing they could not do because the animals penetrated far into the cave; those who went in pursuit of them returned after two days of journeying through these rough passages.
In conclusion, it only remains to state, that the existence of the cavern of Cacahuamilpa remained unknown to everyone, until the year 1833. Before that year, not even the Indians had entered it, because they believed that the stalagmite in the form of a goat was a bad spirit, that guarded the mysteries, which the cavern enclosed; but a criminal who took refuge in it and was there during the period of his pursuit, after which he returned to his home, astonished the inhabitants of Tetecala by his fantastic reports; they made the first exploration and announced their expedition, describing the wonderful cavern. Since then, until now, expeditions have not lacked; unhappily, none of them has been scientific.
