Sylvanus Griswold Morley (b. 1883) was an American archaeologist and pre-Columbian Mayan scholar. Some of his most important work included excavations of Chichen Itza on behalf of the Carnegie Institution and the study and publication of Mayan inscriptions. What is less known about Morley, is that he worked as a spy for the United States during World War I. Some time after his death, it became known that he had been employed by the Office of Naval Intelligence to track German and anti-U.S. Activities in Mexico. His cover as an archaeologist being a legitimate one, however, and despite new discoveries and re-evaluations of his work, his scholarly legacy remains intact. The following is an excerpt from his 1915 book, An Introduction to the Study of the Maya Hieroglyphs:
…there is encountered at the very outset in the study of these elements a condition which renders progress slow and results uncertain. In Egyptian texts of any given period the simple phonetic elements or signs are unchanging under all conditions of composition. Like the letters of our own alphabet, they never vary and may be recognized as unfailingly. On the other hand, in Maya texts each glyph is in itself a finished picture, dependent on no other for its meaning, and consequently the various elements entering into it undergo very considerable modifications in order that the resulting composite character may not only be a balanced and harmonious design, but also may exactly fill its allotted space. All such modifications probably in no way affect the meaning of the element thus mutilated.
Though Morley was an important figure in the study of Mayan culture and language, it seems that he devoted more time to his covert activities than to his archaeological research during the period of the Great War. During that time, it came to light that others in the field were also involved in espionage, and the practice of spying under the guise of science and exploration was, of course, controversial. In 1919, the well known anthropologist, Franz Boas, published a letter of protest in The Nation, stating:
…A person, however, who uses science as a cover for political spying, who demeans himself to pose before a foreign government as an investigator and asks for assistance in his alleged researches in order to carry on, under this cloak, his political machinations, prostitutes science in an unpardonable way and forfeits the right to be classed as a scientist.
Much of Morley’s work and his publications on the Maya are now outdated, however he is still highly regarded for his important restoration work on Mayan sites like Chichen Itza, as well as for initiating research programs for the Carnegie Institution for Science. He is remembered favorably as a voice for the Mayan people and culture. Sylvanus Griswold Morley died in 1948 at the age of 65 in Santa Fe, New Mexico.
