What it is

A twenty-book compendium that organises the learning of Antiquity around the origin of words: grammar, medicine, law, agriculture, minerals and animals. It was the standard encyclopaedia of the early medieval West and survives in hundreds of manuscripts.

Isidore compiles and reorders earlier sources (Pliny, Varro, Servius, Lactantius); his originality lies in organisation, not content. It was unfinished at his death (636) and was arranged into books by Braulio of Zaragoza.

What it led to

  • transmission of classical Latin learning to early medieval Europe
  • a model for later medieval encyclopaedias
  • the Isidorian T-O world map, spread in thousands of copies

Built on

  • Pliny the Elder's Naturalis historia
