The Boxer Codex is a late-16th-century Spanish manuscript produced in the Philippines. It contains 75 colored illustrations of the peoples of China, the Philippines, Japan, Java, the Moluccas, the Ladrones, and Siam. About 270 pages of Spanish text describe these places, their inhabitants and customs. An additional 88 smaller drawings show mythological deities and demons, and both real and mythological birds and animals copied from popular Chinese texts and books in circulation at the time.
The English historian Charles Ralph Boxer purchased the manuscript in 1947 from the collection of Lord Ilchester in London. Boxer recognized the importance of what he called the "Manila Manuscript" and published a paper in 1950 with a detailed description of the codex. He made the manuscript freely available to other researchers for study, and it became known as the Boxer Codex. Boxer eventually sold it to Indiana University, where it is held by the Lilly Library.
