The advance in style that marks the transition from the Ameto to the Arcadia must be largely accredited to Boccaccio himself. The language of the Decameron became the model of cinquecento prose. Sannazzaro, however, wrote in evident imitation not of the structural method only, but of the actual style of the Ameto. Something, it is true, he added beyond the greater mastery of literary form due to training. Even in his most luxuriant descriptions and most sensuous images we find that grace and clearness of vision which characterize the early poetry of the Renaissance proper, and combine in literature the luminous purity of Botticelli and the gem-like detail of Pinturicchio. The mythological affectation of the elder work appears in the younger modified, refined, subordinated; there is the same delight in detailed description, but relieved by greater variety of imagination; while, even in the most laboured passages, there is a poetical feeling as well as a more subjective manner, which, combined with a remarkable power of visualization, saves them from the danger of the catalogue. Again, there is everywhere visible the same artificiality of style which characterizes the Ameto, but purged of its more extravagant elements and less affected and conceited than it became in the works of Lyly and Sidney. Like the Ameto, lastly, but unlike its Spanish and English successors, the Arcadia is purely pastoral, free from any chivalric admixture.
