The only thing to do, then, was to continue his studies. The Wellington Palace drawings had at any rate weaned him of any idea that pure Greek architecture was applicable to modern architectural designing, and he had little knowledge of any other. He started for a tour of the north of Italy. His letters contain few criticisms. Palladio, probably as being most akin to what he had hitherto studied, pleased him more than any other architect. In Venice he fell in with Stackelberg, who had been home to Russia while his travels in Greece were still fresh enough to claim attention, and had been received with every sort of distinction. He was now on his way back to Rome to settle there and bring out the various books he subsequently published. The two joined forces, and having run through all the principal towns, returned southwards to Florence. Shortly after, in company with Lord and Lady Dillon, he went to Rome. He was now a recognised lion, everywhere fêted and made much of. Bartholdy writes of him: "Cockerell est gâté par les femmes." Nevertheless he worked hard. Amongst other things he finished the drawing of the Forum Romanum, the engraving of which is well known. The Duchess of Devonshire wished to insert a reduction of it in her "Virgil," and writes to thank him for "the beautiful drawing you _was_ so good as to do for me." He had left also in Rome the bulk of his, and Haller's, drawings for the intended book on Greek architecture. These he picked up, and having seen all the architecture Italy had to show him, he started in March for England. In Paris he remained some little time. A letter from his father during his stay there is worth transcribing in part. "I send a few hints as to what you should observe in Paris; not things of that high order to which you have so long been used, but yet important to study in order to supply the luxurious indulgence so much coveted by the great here, by whom a complete knowledge of them in their professors of architecture is expected.
