'As the Earl of Pembroke hath an extraordinary Collection of medals and other Antiquities, so he is very particular about them, it being his ambition to have only one of any Curiosity in the world. So that if he happens to have two Coins, however scarce, of a sort, he will immediately destroy one of them, and the same he does with respect to other Rarities, which humour makes most say that he is mad or at least that he is (what no one can deny) very whimsical.' (Hearne 1885, vol. 11, p. 69; Burnett 2020b, pp. 1009-10)
