The constant repetition of his name in that capacity by writers on literary history leads to an impression that his zeal was remarkable, and that its fruits are attested by ample remains. The former of these conclusions is more correct than the latter. Italian authors have been too prone to re-echo vague compliments; their encomiums are lavish rather than discriminating; rhetorical panegyrics, not portraits to the life; accordingly, most of the plaudits thus bestowed on him are mere phrases of rote, reiterated without varying form of added force. Fortunately there remains to us substantial evidence that they were well founded. Muzio, who wrote about half a century after his death, with full access to original documents, tells us that it was his daily habit to be read to during meals, and to discuss with his courtiers such questions in theology, history, or philosophy as thus arose.

It was under him that the Feltrian court first became what Ruscelli has designated it in the motto prefixed to this work, "a fountain which, in the sober truth of history, rather than in poetic vein, may be called a real Hippocrene." No complete list has come to us of the poets and philosophers who found shelter there, nor would it much avail us to recover names few of which merit a better fate than the obscurity that has long overshadowed them. The fifteenth century was more remarkable for the diffusion of learning than for commanding genius. There were earnestness and laborious diligence in abundance, but they were content to follow or imitate foregone conclusions rather than to strike out new and striking turns of thought. Such was the character of many of those works which, composed for or dedicated to this Duke, remain in MS.,[*176] slumbering undisturbed, and deservedly forgotten, on the shelves of the Vatican. Several of them, being devoted to commemorate his actions or his contemporaries, held out to me a rich promise of racy material. But servile in style as in substance, and disfigured by the borrowed diction and engrafted mythology of classic models, they often proved in all respects unsatisfactory references, ill repaying the time bestowed on their examination. It will be necessary to allude more particularly, in our twenty-fourth and twenty-fifth chapters, to such of their authors as
