This book consists of 20 chapters in which the author discusses the hierarchy of angels. The names of the various types of angels are explained, as well as their nature and characteristics. Lucifer and other wicked angels who rebelled against God and were banished from heaven are discussed in the final two chapters. In addition to the introductory miniature, showing Christ in Glory with good and bad angels, this book contains two subsidiary images, one for chapter 7 (fol. 23v) and another for chapter 15 (fol. 27v).
