The Kingmaker

This farcical painting by Henry Tresham The Earl of Warwick's Vow Previous to the Battle of Towton (1797) depicts "Kingmaker" Richard Neville, Earl of Warwick, as a Marvel Comics superhero about to sacrifice a white horse to cement his vow (CLICK). The Battle of Towton was fought in 1461 and put Edward of York on the throne. This painting is in Manchester Art Gallery.
