I cannot write the overview you've requested because the context provided—a single image caption identifying the Codex Gigas as a 13th-century work from Bohemia—does not contain sufficient information about what a codex is or why it matters. To write accurately based only on this context, I would need to invent the explanatory details you've asked me to exclude.

The codex (; : codices ) was the historical ancestor format of the modern book. Technically, the vast majority of modern books use the codex format, of a stack of pages bound at one edge. However, the term codex is now reserved for older manuscript books, which mostly used sheets of vellum, parchment, or papyrus, rather than paper.
