This section contains descriptions of and instructions for various medieval arts. Some of them are from De coloribus et artibus Romanorum, commonly attributed to Eraclius or Heraclius. Books One and Two of this text were probably compiled between the 7th and 12th centuries, while Book Three was added during the 12th and 13th centuries. This manuscript contains items II, III, IV, VI, VII of this text in verse, and prose versions of VIII, IX, X, XI, XIII, XVII, XIX, XXI.

The prose versions are attributed to Theophilus, and appear in his De diversis artibus (On various arts). Theophilus Presbyter, also called Rugerus, is the pseudonymous author or compiler of this text, which was probably first compiled between 1100 and 1120. The work is sometimes called Schedula diversarum artium (List of various arts).
