ITZEBSK, was anciently an officer under an earl, to whom, during his attendance at court, he acted as deputy to look after the affairs of the county. But the name was afterwards employed as an arbitrary title of honour, without any shadow of office pertaining to it, by Henry VI.; when, in 1440, in the eighteenth year of his reign, he created John Beaumont a peer by the name of Viscount Beaumont. A viscount is created by patent, and ranks next below an earl. His mantle is two doublings and a half of plain sur, and his coronet has only a row of pearls close to the circle.
