While he was thus employed on portraits, a gentleman of the name of Cox called on him to agree for a likeness of his daughter; and the picture of Dr. Smith attracted his attention. It indeed appeared to him to evince such a capacity for historical composition, that, instead of then determining any thing respecting his daughter's portrait, he gave an order for an historical picture, allowing the Artist himself to choose the subject. This task had peculiar charms; for the Painter in the course of reading the Bible to his mother some time before, had been led to think that the Trial of Susannah was a fine subject, and he was thus enabled, by the liberality of Mr. Cox, to embody the conceptions of his imagination while they were yet in all the freshness and vigour of original formation. He made his canvas about the size of a half length portrait, on which he introduced not fewer than forty figures. In the execution he followed the rule which he had adopted in painting the Death of Socrates, and drew the principal figures from living models.--It is not known what has become of the Trial of Susannah. In the rebellion of the Colonies, Mr. Cox adhered to the British interest; and his daughter, the last person into whose possession the picture has been traced, having married a British officer, came to England during the war, and the Artist has not heard where she has since resided. In point of composition, Mr. West is of opinion that the Trial of Susannah was superior to the Death of Socrates. In this he is probably correct; for during the interval between the execution of the one and the other, his mind had been enlarged in knowledge by reading, his eye improved by the study of pictorial outline and perspective in the _Camera_, and his touch softened by the portraits which he painted, and particularly by his careful copy of the St. Ignatius. In point of drawing, both pictures were no doubt greatly inferior to many of his subsequent works; but his son, long after he had acquired much celebrity, saw the picture of the Death of Socrates; and was of opinion that it was not surpassed by any of them in variety of composition, and in that perspicuity of narrative which is the grand characteristic of the Artist's genius.
