“Have you heard of these newfangled codexes–codices–codexi–whateveryoucallems?” Celsus says without looking up from his workbench, breaking the monotony of scribal work. “Useless advance in technology I say. What’s wrong with scrolls? You hold a cylindrical tube in your hand and you know you’re holding something worth reading.”
Irenaeus bookmarks his place in his codex and hides it underneath his cloak.
Celsus continues, “They write on both sides of the page, and they cut them up and bind them together! What if some of the pages fall out? What then? That never happens with a scroll.”
