Liber Astrologicus

The Liber Astrologicus, also known as De Rerum Natura or Liber Rotarum, is a unique work. Dedicated to the pious and well learned king Sisebut (610-620) by Saint Isidore, it is a study on social sciences and is divided into three fundamental parts:

  • The first eight chapters are about chronology (days, weeks, months, seasons, etc.);
  • The following chapters, from the 9th to the 28th, are about the universe and celestial bodies (the earth, the sky, the planets, the sun, the moon, the stars, etc.);
  • The last part focuses on the study of atmospheric phenomena and earthquakes (thunder, lightning, rainbows, winds, earthquakes, etc.)

There doesn’t seem to have been real scientific treatises on these subjects before this one, but it is nonetheless difficult to understand the aim of the author. We can grasp his wish to write a treatise on sciences that would be easy to understand for the clergy and monastic school students, based on the assumption that science is the starting element to a good theology, needed to understand the Holy Scriptures.

The book contains seven illustrations, almost all of them in the shape of a circle, to clarify some aspects of the written study.

The original copy, dating back to the 11th century, is kept at the Biblioteca Episcopal de Vic in Spain.
