" Thus Poussin himself, while making no verbal change in the inscription, invites, almost compels, the beholder to mistranslate it by relating the ego to a dead person instead of the tomb, by connecting the et with ego instead of with Arcadia, and by supplying the missing verb in the form of a vixi or fui instead of a sum. The development of his pictorial vision had outgrown the significance of the literary formula, and we may say that those who, under the impact of the Louvre picture, decided to render the phrase Et in Arcadia ego as "I, too, lived in Arcady," rather than as "Even in Arcady, there am I," did violence to Latin grammar but justice to the new meaning of Poussin's composition.
