Etymologiae

Etymological encyclopedia compiled by Isidore of Seville

Etymologiae, also known as the Origines ('Origins'), usually abbreviated Orig., is an etymological encyclopedia compiled by the influential Christian bishop Isidore of Seville towards the end of his life. Isidore was encouraged to write the book by his friend Braulio, Bishop of Saragossa. Etymologiae summarized and organized a wealth of knowledge from hundreds of classical sources; three of its books are derived largely from Pliny the Elder's Natural History. Isidore acknowledges Pliny, but not his other principal sources, namely Cassiodorus, Servius, and Gaius Julius Solinus.
