Speculum maius

Vincent of Beauvais, The Great Mirror

The largest medieval encyclopaedia: in the Speculum naturale India's plants, stones and beasts; in the Speculum historiale Alexander's Indian war, the Brahmans and the letters to Aristotle and Dindimus, an abridged Barlaam and Josaphat, and the reports of Carpini and Simon of Saint-Quentin.
