Aids to the Study of the Maya Codices Sixth Annual Report of the Bureau of Ethnology to the Secretary of the Smithsonian Institution, 1884-85, Government Printing Office, Washington, 1888, pages 253-372

"Aids to the Study of the Maya Codices" by Cyrus Thomas is a scholarly work giving 19th-century researchers a deeper look into the world of ancient Maya writings. The publication looks at the intricate details of Maya codices (books), shedding light on their numbers, symbols, and how they are put together. Thomas tries to help scientists understand these old writings, which are super important for learning about writing in the Americas. Critically, Thomas says that earlier attempts to understand the codices were unsuccessful because they used the wrong ideas and that his research will correct the record, and he also sets the stage for understanding Maya numbers and their place in Maya culture.
