His visits to Vaucluse were rather infrequent; business, he says, detained him often at Avignon, in spite of himself; but still at intervals he passed a day or two to look after his gardens and trees. On one of these occasions, he wrote a pleasing letter to William of Pastrengo, dilating on the pleasures of his garden, which displays liveliness and warmth of heart.
Petrarch had not seen his brother since the latter had taken the cowl in the Carthusian monastery, some five years before. To that convent he paid a visit in February, 1347, and he was received like an angel from heaven. He was delighted to see a brother whom he loved so much, and to find him contented with the life which he had embraced. The Carthusians, who had heard of Petrarch, renowned as the finest spirit of the age, were flattered by his showing a strong interest in their condition; and though he passed but a day and a night with them, they parted so mutually well pleased, that he promised, on taking leave, to send them a treatise on the happiness of the life which they led. And he kept his word; for, immediately upon his return to Vaucluse, he commenced his essay "De Otio Religioso—On the Leisure of the Religious," and he finished it in a few weeks. The object of this work is to show the sweets and advantages of their retired state, compared with the agitations of life in the world.
From these monkish reveries Petrarch was awakened by an astounding public event, namely, the elevation of Cola di Rienzo to the tribuneship of Rome. At the news of this revolution, Petrarch was animated with as much enthusiasm as if he had been himself engaged in the enterprise. Under the first impulse of his feelings, he sent an epistolary congratulation and advice to Rienzo and the Roman people. This letter breathes a strongly republican spirit. In later times, we perceive that Petrarch would have been glad to witness the accomplishment of his darling object—Rome restored to her ancient power and magnificence, even under an imperial government. Our poet received from the Tribune an answer to his epistolary oration, telling him that it had been read to the Roman people, and received with applause. A considerable number of letters passed between Petrarch and Cola.
When we look back on the long connection of Petrarch with the Colonna family, his acknowledged obligations, and the attachment to them which he expresses, it may seem, at first sight, surprising that he should have so loudly applauded a revolution which struck at the roots of their power. But, if we view the matter with a more considerate eye, we shall hold the poet in nobler and dearer estimation for his public zeal than if he had cringed to the Colonnas. His personal attachment to them, who were quite as much honoured by his friendship as he was by theirs, was a consideration subservient to that of the honour of his country and the freedom of his fellow-citizens; "for," as he says in his own defence, "we owe much to our friends, still more to our parents, but everything to our country."
Retiring during this year for some time to Vaucluse, Petrarch composed an eclogue in honour of the Roman revolution, the fifth in his Bucolics. It is entitled "La Pieta Pastorale," and has three speakers, who converse about their venerable mother Rome, but in so dull a manner, that, if Petrarch had never written better poetry, we should not, probably, at this moment, have heard of his existence.
In the midst of all this political fervour, the poet's devotion to Laura continued unabated; Petrarch never composed so many sonnets in one year as during 1347, but, for the most part, still indicative of sadness and despair. In his 116th sonnet, he says:—
"Soleo onde, e 'n rena fondo, e serivo in vento."
I plough in water, build on sand, and write on air.
If anything were wanting to convince us that Laura had treated him, during his twenty years' courtship, with sufficient rigour, this and other such expressions would suffice to prove it. A lover, at the end of so long a period, is not apt to speak thus despondingly of a mistress who has been kind to him.
It seems, however, that there were exceptions to her extreme reserve. On one occasion, this year, when they met, and when Petrarch's eyes were fixed on her in silent reverie, she stretched out her hand to him, and allowed him to detain it in his for some time. This incident is alluded to in his 218th sonnet.
If public events, however, were not enough to make him forget his passion for Laura, they were sufficiently stirring to keep his interest in them alive. The head of Rienzo was not strong enough to stand the elevation which he had attained. Petrarch had hitherto regarded the reports of Rienzo's errors as highly exaggerated by his enemies; but the truth of them, at last, became too palpable; though our poet's charitable opinion of the Tribune considerably outlasted that of the public at large.
