Of a much later date is a royal monument, not indeed of a king, but of the son and father of kings, namely, John of Gaunt. He died in 1399, and his tomb in St. Paul's was as magnificent as those of his father in the Confessor's Chapel at Westminster, and of his son at Canterbury. It was indeed a Chantry founded by Henry IV. to the memory of his father and mother, Gaunt and Blanche of Lancaster. She was Gaunt's first wife (d. 1369), and bore him not only Henry IV., but Philippa, who became wife of the King of Portugal, and Elizabeth, wife of John Holland, Earl of Huntingdon. It was through Blanche that Gaunt got his dukedom of Lancaster. She died of plague in 1369, during his absence in the French Wars, and was buried here. Before his return to England he had married (in 1371) Constance, daughter of Pedro the Cruel, and hereby laid claim to the crown of Castile, as the inscription on his monument recorded. Their daughter married Henry, Prince of the Asturias, afterwards King of Castile. Constance died in 1394, and was also buried in St. Paul's, though her effigy was not on the tomb. In January, 1396, he married Catharine Swynford, who had already borne him children, afterwards legitimised. One of them was the great Cardinal Beaufort; another, John Beaufort, Earl of Somerset, was the grandfather of Margaret Tudor, mother of Henry VII. Gaunt's third wife (d. 1403) is buried at Lincoln. The long inscription on the monument closed with the words, "Illustrissimus hic princeps Johannes cognomento Plantagenet, Rex Castilliae et Legionis, Dux Lancastriae, Comes Richmondiae, Leicestriae, Lincolniae et Derbiae, locum tenens Aquitaniae, magnus Seneschallus Angliae, obiit anno XXII. regni regis Ricardi secundi, annoque Domini MCCCXCIX." Close by John of Gaunt, between the pillars of the 6th bay of the Choir, was the tomb of WILLIAM HERBERT (1501-1569), first Earl of Pembroke of the second creation, a harum-scarum youth, who settled down into a clever politician, and was high in favour with Henry VIII., who made him an executor of his will, and nominated him one of the Council of twelve for Edward VI. He went through the reign of Mary not without suspicion of disloyalty, but was allowed to hold his place at Court, and in the reign of Queen Elizabeth he was accused of favouring the Queen of Scots, though here also he overcame the suspicions, and did not lose his place. He married Anne, the sister of Queen Catherine Parr, and they were both buried in St. Paul's. JOHN OF CHISHULL, who filled the see from 1274-1280, and was Edward III.'s Chancellor, held a great number of valuable posts together. This may have produced the mental incapacity into which he fell. Archbishop Peckham had to appoint a commission to manage the diocese. He was buried against the wall of the North Aisle, not far from John of Gaunt.
