In the early phase of the philosophy of art--a phase lingering on to our own day in the works of certain critics--the peculiarities of a work of art were explained by the peculiarities of character of the artist: the paintings of Raphael and the music of Mozart partook of the gentleness of their life; while the figures of Michelangelo and the compositions of Beethoven were the outcome of their misanthropic ruggedness of temper. The insufficiency, often the falseness, of such explanations became evident when critics began to perceive that the works of one time and country usually possessed certain common peculiarities which did not correspond to any resemblance between the characters of their respective artists; peculiarities so much more dominant than any others, that a statue or a picture which was unsigned and of obscure history was constantly attributed to half-a-dozen contemporary sculptors or painters by half-a-dozen equally learned critics. The recognition of this fact led to the substitution of the _environment_ (the _milieu_ of Monsieur Taine) as an explanation of the characteristics, no longer of a single work of art, but of a school or group of kindred works. Greek art henceforth was the serene outcome of a serene civilisation of athletes, poets, and philosophers, living with untroubled consciences in a good climate, with slaves and helots to char for them while they ran races, discussed elevated topics, and took part in Panathenaic processions, riding half naked on prancing horses, or carrying olive branches and sacrificial vases in honour of a divine patron, in whom they believed only as much as they liked. And the art of the Middle Ages was the fantastic, far-fetched, and often morbid production of nations of crusaders and theologians, burning heretics, worshipping ladies, seeing visions, and periodically joining hands in a vertiginous death-reel, whose figures were danced from country to country. This new explanation, while undoubtedly less misleading than the other one, had the disadvantage of straining the characteristics of a civilisation or of an art in order to tally with its product or producer; it forgot that Antiquity was not wholly represented by the frieze of the Parthenon, and that the Gothic cathedrals and the frescoes of Giotto had characteristics more conspicuous than morbidness and insanity.
