De Proprietatibus Rerum

De Proprietatibus Rerum is a medieval encyclopedia written by Bartholomaeus Anglicus in the 13th century. The text consists of 19 books covering topics from God and angels to colors, numbers, weights and measures. The work draws heavily from classical and early medieval authorities, synthesizing knowledge from Aristotle, Pliny, Isidore of Seville and others into a comprehensive reference text. It remained a standard reference work for several centuries and was translated into multiple languages including English, French, Dutch and Spanish. Each book focuses on a different domain of knowledge, moving from divine and celestial matters down through the physical world to plants, animals and minerals. The organizational structure reflects the medieval view of a hierarchical universe descending from God to the earthly realm. The encyclopedia represents a medieval Christian worldview while attempting to catalog and explain natural phenomena through the scientific understanding of its time. Its enduring influence helped shape how medieval Europeans understood and classified the natural world.
