William Cosmo Monkhouse,
Dictionary of National Biography…
(1887)
“ As Suffolk to Constable and Norfolk to Old Crome, so was North Wales to Cox. He painted well wherever he went—London, Hereford, Yorkshire, Lancashire, or Calais— but it was Wales that he loved and understood best; it was Wales that drew from him his deepest notes of poetry, his noblest sympathy with his kind. He is the greatest interpreter of her scenery and her life. ”
