Lucian.[10] The improvements in painting which Pliny ascribes to him, of having dressed the heads of his females in variegated veils and _bandeaus_, and robed them in lucid drapery, of having gently opened the lips, given a glimpse of the teeth, and lessened the former monotony of face, such improvements, I say, were surely the most trifling part of a power to which the age of Apelles and that of Quintilian paid equal homage: nor can it add much to our esteem for him, to be told by Pliny that there existed, in the portico of Pompey, a picture of his with the figure of a warrior in an attitude so ambiguous as to make it a question whether he were ascending or descending. Such a figure could only be the offspring of mental or technic imbecility, even if it resembled the celebrated one of a Diomede carrying off the palladium with one and holding a sword in the other hand, on the intaglio inscribed, I think, with the name of Dioscorides. With this simplicity of manner and materials the art seems to have proceeded from Polygnotus, Aglaophon, Phidias, Panænus, Colotes, and Evenor, the father of Parrhasius, during a period of more or less disputed Olympiads, to the appearance of Apollodorus the Athenian, who applied the essential principles of Polygnotus to the delineation of the species, by investigating the leading forms that discriminate the various classes of human qualities and passions. The acuteness of his taste led him to discover that as all men were connected by one general form, so they were separated each by some predominant power, which fixed character and bound them to a class: that in proportion as this specific power partook of individual peculiarities, the farther it was removed from a share in that harmonious system which constitutes nature, and consists in a due balance of all its parts; thence he drew his line of imitation, and personified the central form of the class, to which his object belonged; and to which the rest of its qualities administered without being absorbed: agility was not suffered to destroy firmness, solidity, or weight; nor strength and weight agility; elegance did not degenerate to effeminacy, or grandeur swell to hugeness; such were his principles of style: his expression extended them to the mind, if we may judge from the two subjects mentioned by Pliny, in which he seems to have personified the characters of devotion and impiety; _that_, in the adoring figure of a priest, perhaps of Chryses, expanding his gratitude at the shrine of the God whose arrows avenged his wrongs and restored his daughter: and _this_, in the figure of Ajax wrecked, and from the sea-swept rock hurling defiance unto the murky sky. As neither of these subjects can present themselves to a painter's mind without a contrast of the most awful and terrific tones of colour, magic of light and shade, and unlimited command over the tools of art, we may with Pliny and with Plutarch consider Apollodorus as the first assertor of the
