Isidore

Isidore, of Seville (560-636), a very celebrated ecclesiastic and compiler of glosses at the beginning of the 7th century, was born at Carthagena, where his father Severanius was prefect, or at Seville. He succeeded Leander as Bishop of Seville (600). He presided at two half-ecclesiastical, half-civil councils at Seville (618 or 619), and at Toledo (633), when the bases of the constitution which lasted down to the 15th century were laid. In the eighth council at Toledo the title egregius was conferred on him for his great learning and devotion to literature. His most important work, Originnm sive Etytnoloylarum Libri xx., is an epitome of an encyclopaedia.
