Portrait of William Herbert, 3rd Earl of Pembroke by Daniel Mytens (1625) William Herbert, 3rd Earl of Pembroke, (8 April 1580 – 10 April 1630) was the son of Henry Herbert, 2nd Earl of Pembroke and his third wife Mary Sidney. Chancellor of theUniversity of Oxford, he founded Pembroke College, Oxford with King James. He was warden of the Forest of Dean, and constable of St Briavels from 1608 to 1630. He served as Lord Chamberlain from 1615 to 1625.
Henry VIII at eighteen, the year he became king and married his first wife, Catherine of Aragon, who was turning 24. (I think he's rather funny looking here, but I guess given how tall he was, he was probably a tall, gangly teen until he filled out. He was supposed to be very athletic and musical.)
Edward VI. This portrait is an obvious attempt to link Edward, the only legitimate son of Henry VIII, to his father. That pose is unmistakable. Unfortunately, Edward died while he was still a teenager, so he never had the chance to develop the mature confidence that he's (probably) feigning here.
