To Barry, the artist, who was in Rome, he wrote: "Whoever is resolved to excel in painting, or indeed in any other art, must bring all his mind to bear upon that one object, from the moment he rises till he goes to bed. The effect of every object that meets the painter's eye may give a lesson, provided his mind is calm, unembarrassed with other objects, and open to instruction. This general attention, with other studies connected with the art, which must employ the artist in his closet, will be found sufficient to fill up life, if it were much longer than it is.... Whoever has great views, I would recommend to him, whilst at Rome, rather to live on bread and water than lose those advantages which he can never hope to enjoy a second time, and which he will find only in the Vatican.... The Capella Sistina is the production of the greatest genius that was ever employed in the arts.... If you neglect visiting the Vatican often, and particularly the Capella Sistina, you will neglect receiving that peculiar advantage which Rome can give above all other cities in the world. In other places you will find casts from the antique, and capital pictures of the great masters, but it is _there_ only that you can form an idea of the dignity of the art, as it is there only that you can see the works of Michael Angelo and Raphael. If you should not relish them at first, which may probably be the case, as they have none of those qualities which are captivating at first sight, never cease looking till you feel something like inspiration come over you, till you think every other painter insipid in comparison, and to be admired only for petty excellences." In 1770, Sir Joshua painted a picture called "The Babes in the Woods," which is now in the collection of Viscount Palmerston. Reynolds loved to find picturesque beggar children on the street, and would send them to his studio to be painted. Northcote says he would often hear the voice of a little waif, worn with sitting, say plaintively, "Sir,--sir,--I'm tired!" "It happened once," says Leslie, "as it probably often did, that one of these little sitters fell asleep, and in so beautiful an attitude that Sir Joshua instantly put away the picture he was at work on, and took up a fresh canvas. After sketching the little model as it lay, a change took place in its position; he moved his canvas to make the change greater, and, to suit the purpose he had conceived, sketched the child again. The result was the picture of the 'Babes in the Wood.'" This year, Sir Joshua brought the thirteen-year-old daughter, Theophila, of his widowed sister, Mrs. Palmer, to live with him in London, and three years later her elder sister, Mary, who afterward became the Marchioness of Thomond. He painted Theophila, called Offy, as "A Girl Reading," at which the young miss was offended, saying, "I think they might have put 'A Young Lady.'"
