Sacred mysteries among the Mayas and the Quiches, 11,500 years ago. Their relation to the sacred mysteries of Egypt, Greece, Chaldea and India

Augustus Le Plongeon (May 4, 1826 – December 13, 1908) was a French-American photographer, amateur archeologist, antiquarian and author who studied the pre-Columbian ruins of America, particularly those of the Maya civilization on the northern Yucatán Peninsula. While his writings contain many controversial notions that were not well received by his contemporaries and were later disproven, Le Plongeon left a lasting legacy in his photographs documenting the ancient ruins. He should also be regarded as one of the earliest proponents of Mayanism.
