The mere fact that the _Pléiade_ formed a definite school, with common principles and a fixed poetical creed, differentiates them in a striking way from the poets who had preceded them. They worked with no casual purpose, no merely professional art, but with a high sense of the glory of their calling and a noble determination to give to the Muses whom they worshipped only of their best. They boldly asserted--in Du Bellay's admirable essay, _La Défense et Illustration de la Langue Française_--the right of the French language to stand beside those of the ancients, as a means of poetical expression; and they devoted their lives to the proof of their doctrine. But their respect for their own tongue by no means implied a neglect of the Classics. On the contrary, they shared to the full the adoration of their contemporaries for the learning and the literature of the Ancient World. They were scholars as well as poets; and their great object was to create a tradition in the poetry of France which should bring it into accord with the immortal models of Greece and Rome. This desire to imitate classical literature led to two results. In the first place, it led to the invention of a great number of new poetical forms, and the abandonment of the old narrow and complicated conventions which had dominated the poetry of the Middle Ages. With the free and ample forms of the Classics before them, Ronsard and his school enfranchised French verse. Their technical ability was very great; and it is hardly too much to say that the result of their efforts was the creation of something hitherto lacking in French literature--a poetical instrument which, in its strength, its freedom, its variety of metrical resources, and its artistic finish, was really adequate to fulfil the highest demands of genius. In this direction their most important single achievement was their elevation of the 'Alexandrine' verse--the great twelve-syllabled rhyming couplet--to that place of undisputed superiority over all other metres which it has ever since held in French poetry. But the _Pléiade's_ respect for classical models led to another and a far less fortunate result. They allowed their erudition to impinge upon their poetry, and, in their eagerness to echo the voice of antiquity, they too often failed to realize the true bent either of their own language or their own powers. This is especially obvious in the longer poems of Ronsard--his _Odes_ and his _Françiade_--where all the effort and skill of the poet have not been enough to save his verse from tedium and inflation. The Classics swam into the ken of these early discoverers in such a blaze of glory that their eyes were dazzled and their feet misled. It was owing to their very eagerness to imitate their great models exactly--to 'ape the outward form of majesty'--that they failed to realize the true inward spirit of Classical Art.
