A richer and more fruitful vein was discovered in expanding and completing the Greco-Roman mythology. In this too Italian poetry began early to take a part, beginning with the ‘Teseide’ of Boccaccio, which passes for his best poetical work. Under Martin V. Maffeo Vegio wrote in Latin a thirteenth book to the Æneid; besides which we meet with many less considerable attempts, especially in the style of Claudian--a ‘Meleagris,’ a ‘Hesperis,’ and so forth. Still more curious were the newly-invented myths, which peopled the fairest regions of Italy with a primæval race of gods, nymphs, genii, and even shepherds, the epic and bucolic styles here passing into one another. In the narrative or conversational eclogue after the time of Petrarch, pastoral life was treated in a purely conventional manner,[603] as a vehicle of all possible feelings and fancies; and this point will be touched on again in the sequel. For the moment, we have only to do with the new myths. In them, more clearly than anywhere else, we see the double significance of the old gods to the men of the Renaissance. On the one hand, they replace abstract terms in poetry, and render allegorical figures superfluous; and, on the other, they serve as free and independent elements in art, as forms of beauty which can be turned to some account in any and every poem. The example was boldly set by Boccaccio, with his fanciful world of gods and shepherds who people the country round Florence in his ‘Ninfale d’Ameto’ and ‘Ninfale Fiesolano.’ Both these poems were written in Italian. But the masterpiece in this style was the ‘Sarca’ of Pietro Bembo,[604] which tells how the rivergod of that name wooed the nymph Garda; of the brilliant marriage feast in a cave of Monte Baldo; of the prophecies of Manto, daughter of Tiresias; of the birth of the child Mincius; of the founding of Mantua; and of the future glory of Virgil, son of Mincius and of Maia, nymph of Andes. This humanistic rococo is set forth by Bembo in verses of great beauty, concluding with an address to Virgil, which any poet might envy him. Such works are often slighted as mere declamation. This is a matter of taste on which we are all free to form our own opinion.
