This update is mostly about four encyclopedia articles, either newly added or substantially updated.

  • Albertus Magnus (De animalibus): Albertus Magnus, also known as Albert the Great, Albert of Cologne and Saint Albert, was born shortly before 1200 CE (perhaps circa 1193) and died in 1280 CE. He was a Dominican monk, a bishop, a scholar, an author and a commentator on the works of Aristotle. The De animalibus (On animals) is an encyclopedic account of animal knowledge of the time. The first 19 books are based on the 19 books of Aristotle’s De animalibus, but Albert expanded Aristotle’s text considerably, adding commentary and more information.
  • Arnoldus Saxo (De floribus rerum naturalium): The De floribus rerum naturalium is an encyclopedia, albeit a short one, covering zoology, mineralogy, and astronomy, but the the zoological parts dominate, with chapters on quadrupeds, birds, fish and reptiles. Arnoldus used the Latin translation by Michel Scotus of Aristotle’s De animalibus, which was published around 1220, so the De floribus rerum naturalium has to have been written after 1220 and probably in the 1230s.
  • Alexander Neckam (De naturis rerum): This is a moralized encyclopedia. De naturis rerum, more completely titled De naturis rerum et super Ecclesiasten (On the Natures of Things and on Ecclesiastes), was written in the early thirteenth century. The first part of the text is an encyclopedia in two books. An additional three books, not directly connected to the first two, make up the second part; the texts in that part are an extended commentary on the biblical book of Ecclesiastes. It is possible the two parts were originally intended as two separate works.
  • Rabanus Mauris (De rerum naturis): Another moralized encyclopedia. De rerum naturis (On the Nature of Things), also known as De universo, is an encyclopedia in 22 books, covering a large range of subjects. It was written between 842 and 847. Rabanus’ stated intent was to compile an encyclopedic handbook for preachers. He drew on earlier sources for his information, particularly the Etymologiae of Isidore of Seville, but the organization of the material was his own invention.

Some of the manuscripts of these encyclopedias are illustrated, so there are a few hundred new images online. There are also around 100 new manuscripts, plus some new bibliography entries.

And that’s all, folks!
