Books by Augustus le Plongeon.

French-American photographer, 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.
