CASTELLI, DR EDMUND (1606-1685), a learned English divine and orientalist. He was educated at Cambridge, where he became master of Catharine Hall and Arabic professor; and was afterwards appointed canon of Canterbury. He had a large share in the publication of the London Polyglott, and wrote the Lexicon Heptaglotton or dictionary of seven languages. On this latter work, which occupied a great part of his life, he expended no less than £12,000. When printed, the copies remained unsold, and were afterwards destroyed by vermin so as to be utterly unsaleable. He obtained several ecclesiastical preferments; and at the time of his death was rector of Higham Gobyon, in Bedfordshire. He bequeathed his oriental MSS. to the university of Cambridge, on condition that his name should be written on every copy.
