In the four preceding chapters I have sketched the rise and progress of Italian humanism with more minuteness than need be now employed upon the history of its further development. By the scholars of the first and second period the whole domain of ancient literature was reconquered; the classics were restored in their integrity to the modern world. Petrarch first inflamed the enthusiasm without which so great a work could not have been accomplished, his immediate successors mastered the Greek language, and explored every province of antiquity. Much still remained, however, to be achieved by a new generation of students: for as yet criticism was but in its cradle; the graces of style were but little understood; indiscriminate erudition passed for scholarship, and crude verbiage for eloquence. The humanists of the third age, still burning with the zeal that animated Petrarch, and profiting by the labours of their predecessors, ascended to a higher level of culture. It is their glory to have purified the coarse and tumid style of mediæval Latinists, to have introduced the methods of comparative and æsthetic criticism, and to have distinguished the characteristics of the authors and the periods they studied.
The salient features of this third age of humanism may be briefly stated. Having done their work by sowing the seeds of culture broadcast, the vagrant professors of the second period begin to disappear, and the republic of letters tends to crystallise round men of eminence in coteries and learned circles. This, therefore, is the age of the academies. Secondly, it is noticeable that Italian literature, almost totally abandoned in the first fervour of enthusiasm for antiquity, now receives nearly as much attention as the classics. Since the revival of Italian in the golden age of the Renaissance will form the subject of my final volume, the names of Lorenzo de' Medici and Poliziano at Florence, of Boiardo at Ferrara, and of Sannazzaro at Naples may here suffice to indicate the points of contact between scholarship and the national literature. A century had been employed in the acquisition of humanistic culture; when acquired, it bore fruit, not only in more elegant scholarship, but also in new forms of poetry and prose for the people. A third marked feature of the period is the establishment of the printing press. The energy wherewith in little more than fifty years the texts of the classic authors were rendered indestructible by accident or time, and placed within the reach of students throughout Europe, demands particular attention in this chapter.
