"Philopoemen was a man eminent for his sagacity and experience in choosing ground, and in leading armies; to which he formed his mind by perpetual meditation, in times of peace as well as war. When, in any occasional journey, he came to a strait, difficult passage, if he was alone, he considered with himself, and if he was in company he asked his friends, what it would be best to do if in this place they had found an enemy, either in the front or in the rear, on the one side or on the other? 'It might happen,' says he, 'that the enemy to be opposed might come on drawn up in regular lines, or in a tumultuous body formed only by the nature of the place.' He then considered a little what ground he should take; what number of soldiers he should use, and what arms he should give them; where he should lodge his carriages, his baggage, and the defenceless followers of his camp; how many guards, and of what kind, he should send to defend them: and whether it would be better to press forward along the pass, or recover by retreat his former station: he would consider likewise where his camp could most commodiously be formed; how much ground he should enclose within his trenches; where he should have the convenience of water, and where he might find plenty of wood and forage; and when he should break up his camp on the following day, through what road he could most safely pass, and in what form he should dispose his troops. With such thoughts and disquisitions he had from his early years so exercised his mind, that on these occasions nothing could happen which he had not been already accustomed to consider." I cannot help imagining that I see a promising young Painter equally vigilant, whether at home or abroad, in the streets or in the fields. Every object that presents itself is to him a lesson. He regards all nature with a view to his profession, and combines her beauties, or corrects her defects. He examines the countenance of men under the influence of passion; and often catches the most pleasing hints from subjects of turbulence or deformity. Even bad pictures themselves supply him with useful documents; and, as Lionardo da Vinci has observed, he improves upon the fanciful images that are sometimes seen in the fire, or are accidently sketched upon a discoloured wall. The Artist who has his mind thus filled with ideas, and his hand made expert by practice, works with ease and readiness; whilst he who would have you believe that he is waiting for the inspirations of Genius, is in reality at a loss how to begin; and is at last delivered of his monsters with difficulty and pain.
