Timeline

1. c. 400–800Christian Mediterranean world · MediterraneanFrom late antiquity to the Carolingian era, parchment codices gradually replaced papyrus scrolls; the advantages of writing on both sides and page-by-page reference made the codex the standard format for Bibles and law codes, with monastery scriptoria controlling the cutting, folding, and leather-binding processes.
2. c. 1341–1350Left Bank booksellers' district, Paris · ParisIn the 1340s, booksellers (libraires) around the universities of Paris, Oxford, and Bologna organized commercial scriptoria to mass-produce philosophical, medical, and legal codices; illuminated gospels circulated alongside secular literary codices such as Dante's Divine Comedy, and the codex became the standard book form for scholars and clerics' daily reading.
3. c. 1350–1400Low Countries and Rhineland · RhinelandAfter the Black Death devastated scribal labor in the 1350s, surviving workshops accelerated production through division of labor; Bruges and Cologne became northern centers of codex production, and the parchment codex maintained its dominance in the market for missals, prayer books, and university textbooks until the rise of printing.
