Mr. Wells’s daughter states that not only did the “Liber Studiorum” entirely owe its existence to her father’s persuasion, but the divisions into “Pastoral,” “Elegant Pastoral,” “Marine,” &c., were also suggested by him. Turner determined to print and publish and sell the “Liber” himself, but to employ an engraver. His first choice fell on “Mr. F. C. Lewis, the best aquatint engraver of the day, who at the very time was at work on facsimiles of Claude’s drawings.”[23] With him he soon quarrelled. The terms were, that Turner was to etch and Lewis to aquatint at five guineas a plate. The first plate, _Bridge and Goats_, was finished and accepted by Turner, though not published till April, 1812; but the second plate Turner gave Lewis the option of etching as well as aquatinting, and he etched it accordingly, and sent a proof to Turner, raising his charge from five guineas to eight, in consideration of the extra work. Turner praised it, but declined to have the plate engraved, on the ground that Lewis had raised his charges. This ended Mr. Lewis’s connection with the “Liber,” and Turner next employed Mr. Charles Turner, the mezzotint engraver, but he had to pay him eight guineas a plate. Charles Turner agreed to engrave fifty plates at this price, but after he had finished twenty, he wished to raise his charge to ten guineas, which led to a quarrel. With reference to these quarrels of Turner with his engravers, Mr. Thornbury says, “The painter who had never had quarter given to him when he was struggling, now in his turn, I grieve to say, gave no quarter,” and “inflexibly exacting as he was, Turner could not understand how an engraver who had contracted to do fifty engravings should try to get off his bargain at the twenty-first.” This, like most of Thornbury’s statements, is utterly untrustworthy. There is no evidence to show that a hard bargain was ever driven with him when he was struggling, there is no word of any dispute with engravers till he began to employ them himself, and as to his “not being able to understand” how any man should endeavour to obtain more than the price contracted for, it was exactly what he tried to do himself, when afterwards employed by Cooke.
