Isidore of Seville (Latin: Isidorus Hispalensis; c. 560 – 4 April 636) was a Spanish scholar, theologian, and archbishop of Seville. He is widely regarded, in the words of 19th-century historian Montalembert, as "the last scholar of the ancient world". His fame after his death was based on his Etymologiae, an etymological encyclopedia that assembled extracts of many books from classical antiquity that would have otherwise been lost. This work also helped standardize the use of the period (full stop), comma, and colon.
