While Trumbull and Stuart were together as pupils of Mr. West, Stuart being the senior student, and more advanced in the art, Trumbull frequently submitted his works to him for the benefit of his remarks. Stuart told Mr. Sully, from whom we derive the anecdote, that on one occasion he was excessively puzzled by the drawing, “and after turning it this way and that, I observed, ‘Why, Trumbull, this looks as if it was drawn by a man with but one eye.’ Trumbull appeared much hurt, and said, ‘I take it very unkindly, sir, that you should make the remark.’ I couldn't tell what he meant, and asked him. ‘I presume, sir,’ he answered, ‘that you know I have lost the sight of one eye, and any allusion to it, in this manner, is illiberal.’ Now I never suspected it, and only the oddness of the drawing suggested the thing.” We have heard from Stuart’s companions in Boston, the same story, in nearly the same words, and when he told it to them, he went into a long dissertation on optics to prove, that a man, with but the sight of one eye, could not possibly draw truly. This notion Sully thought perfectly idle, and only one of Stuart’s whims, who could lecture most eloquently on any subject, from the anatomy of a man, to the economy of his shoe-tie.
