Thomas de Berkeley, 5th Baron Berkeley Thomas de Berkeley, 5th Baron Berkeley Thomas de Berkeley, 5th Baron Berkeley (5 January 1352/53 – 13 July 1417), "The Magnificent", of Berkeley Castle and of Wotton-under-Edge in Gloucestershire, was an English peer and an admiral. His epithet, and that of each previous and subsequent head of his family, was coined by John Smyth of Nibley (d.1641), steward of the Berkeley estates, the biographer of the family and author of "Lives of the Berkeleys". He was born at Berkeley Castle in Gloucestershire, the son and heir of Maurice de Berkeley, 4th Baron Berkeley by his wife Elizabeth le Despencer. In
James Berkeley Berkeley died on 24 June 1327, having been murdered and having suffered the destruction and despoilation of his manors, according to the account by his successor John de Grandisson. Berkeley was buried in Exeter Cathedral, against the north wall of the south ambulatory, where survives his chest tomb. It is devoid of the monumental brass which originally adorned the Purbeck marble ledger stone top, in the form of a demi-effigy of a bishop wearing a mitre, the indent of which is still visible. Following the Reformation the brass was stripped away in 1561 on the orders of the Cathedral authorities.
