Watch the video, or read on below!

A codex is a Latin term that refers to a manuscript, typically handwritten and bound in book form. Books might seem like an old technology, but that wasn’t always the case.

Before codices (the plural of codex), people in many parts of the world wrote on things like scrolls, clay or stone tablets, or papyrus. The transition to the codex was a big change in the history of writing. Readers could now flip to specific sections more quickly, and they were easier to carry for information on the go.

When the Spanish arrived in Mexico in the 16th century, they recognized that these Indigenous manuscripts were like European books and applied the name “codex.”

The massive 12-book Florentine Codex is a combination of European and Mexican bookmaking traditions and gives a rare look into the world of Nahua people in Mexico before and during colonization—in their own words. The codex is written in Nahuatl, Spanish, and also includes captivating imagery to help tell these rich stories.

Today, “codex” can refer to any type of book, but especially big works like the Florentine Codex. Want to check out it yourself? The physical copy is located at the Medici Library in Florence, Italy. Or, you can check out its colorful illustrations and translated text in Getty’s new online edition.
