"[Corot] has the devil to seldom within him. However inadequate and even unjust this expression may be, I chose it as approximately giving the reason which prevents this serious artist from dazzling and astonishing us. He does astonish – I freely admit – but slowly; he does enchant – little by little; but you have to know how to penetrate into the science of his art.. ..an infallible strictness of harmony."
