Each scribe must have a desk to work at, and he should keep this prepared with parchment, quills, and ink kept in ink-horns or pots. He will need also his awl and stylus for ruling the parchment and his penknife for sharpening quills and scraping out errors in the text if he is so careless as to make them. A chair or stool of the proper height should be provided as well.
