Thomas Andrew Archer, 1911 Encyclopædia Britannica, Volume 28… (1911)
“ As the fifteenth book of the Speculum Doctrinale is a summary of the Speculum Naturale, so the Speculum Historiale may be regarded as the expansion of the last book of the same work. It consists of thirty-one books divided into 3793 chapters. The first book opens with the mysteries of God and the angels, and then passes on to the works of the six days and the creation of man. It includes dissertations on the various vices and virtues, the different arts and sciences, and carries down the history of the world to the sojourn in Egypt. ”
