Petrarch was fortunate in acquiring the friendship and favour of some of the most eminent men of his time. Jacopo Colonna, Bishop of Lombés, invited him to his palace at the foot of the Pyrenees. He gratified his intense desire to see the world by travelling through France and Germany, and subsequently visiting many cities of Italy. In Rome he was welcomed by Stefano Colonna, the head of that illustrious family, but Rome was then deserted and lonely, and Petrarch soon returned to the more brilliant circles of Avignon. He found a delicious retreat fifteen miles from Avignon, at Vaucluse, a pleasant valley, watered by the river Sorga. Here he produced some of his loveliest Italian poems, and some of his most elaborate Latin compositions. So uncertain are the vicissitudes of literary taste, and so little do even great poets know where their real strength lies, that Petrarch treated his sonnets and canzoni, to which alone he is indebted for his immortality, as the amusement of his leisure hours, and devoted all his care and study to those Latin works which are now read only by the curious. He composed a ponderous epic poem in Latin hexameters, and gave it to the world under the title of _Africa._ It procured for him an immense reputation. The whole literary world read it with avidity, and all Europe resounded with his praises. Paris and Rome simultaneously invited him to be crowned with the laurel within their walls. He decided to accept the invitation of Rome; but before the ceremony he went to Naples, where he was received with enthusiasm by King Robert, who was so enraptured with the _Africa_ that he begged it should be dedicated to himself. This request the poet gladly granted, and he left for Rome laden with signs of Royal favour. He was crowned in the Capitol by the Senator Orso dell' Anguillara, on the 8th of April, 1341, and the laurel wreath bestowed upon him he hung up as a votive offering in the Church of St. Peter. Petrarch was one of those who succeed in everything; and, as if the distinctions already showered upon him were not enough, he was, when visiting Parma, invited to the Court by Azzo da Correggio, and within a short time sent as his envoy to Clement VI at Avignon. He wrote a Latin poem advising the Pope to return to Rome, and his Holiness, though he did not take the advice, was so delighted with the poem that he bestowed a valuable benefice on its author.
