Speculum majus

encyclopaedia by Vincent of Beauvais
Also known as: “Great Mirror”

Quick Summary

The Speculum majus (Great Mirror), compiled by Vincent of Beauvais around 1244, was a monumental encyclopaedia in the 13th century. It was likely the most extensive European encyclopaedia until the 18th century.1

The work was divided into three original parts:
* Historical: Covering Western history from Creation to the time of Louis IX.1
* Natural: Summarizing all known natural history and science.1
* Doctrinal: Compiling European literature, law, politics, and economics.1

A fourth part, the Speculum morale (Mirror of Morals), was added later. Vincent of Beauvais drew heavily on classical scholarship, showing respect for figures like Aristotle and Cicero, which indicated a shift in attitudes toward antiquity during the 12th-century Renaissance of learning. The Speculum majus was highly influential, with translations and reprints continuing for centuries.1
