Next day he departed with Sacromoro di Pomieres, whose company was a great solace to him. They arrived at Basle, where the Emperor was expected; but they waited in vain for him a whole month. "This prince," says Petrarch, "finishes nothing; one must go and seek him in the depths of barbarism." It was fortunate for him that he stayed no longer, for, a few days after he took leave of Basle, the city was almost wholly destroyed by an earthquake.
Petrarch arrived at Prague in Bohemia towards the end of July, 1356. He found the Emperor wholly occupied with that famous Golden Bull, the provisions of which he settled with the States, at the diet of Nuremberg, and which he solemnly promulgated at another grand diet held at Christmas, in the same year. This Magna Charta of the Germanic constitution continued to be the fundamental law of the empire till its dissolution.
Petrarch made but a short stay at Prague, notwithstanding his Majesty's wish to detain him. The Emperor, though sorely exasperated against the Visconti, had no thoughts of carrying war into Italy. His affairs in Germany employed him sufficiently, besides the embellishment of the city of Prague. At the Bohemian court our poet renewed a very amicable acquaintance with two accomplished prelates, Ernest, Archbishop of Pardowitz, and John Oczkow, Bishop of Olmütz. Of these churchmen he speaks in the warmest terms, and he afterwards corresponded with them. We find him returned to Milan, and writing to Simonides on the 20th of September.
Some days after Petrarch's return from Germany, a courier arrived at Milan with news of the battle of Poitiers, in which eighty thousand French were defeated by thirty thousand Englishmen, and in which King John of France was made prisoner.[M] Petrarch was requested by Galeazzo Visconti on this occasion to write for him two condoling letters, one to Charles the Dauphin, and another to the Cardinal of Boulogne. Petrarch was thunderstruck at the calamity of King John, of whom he had an exalted idea. "It is a thing," he says, "incredible, unheard-of, and unexampled in history, that an invincible hero, the greatest king that ever lived, should have been conquered and made captive by an enemy so inferior."
On this great event, our poet composed an allegorical eclogue, in which the King of France, under the name of Pan, and the King of England, under that of Articus, heartily abuse each other. The city of Avignon is brought in with the designation of Faustula. England reproaches the Pope with his partiality for the King of France, to whom he had granted the tithes of his kingdom, by which means he was enabled to levy an army. Articus thus apostrophizes Faustula:—
Ah meretrix oblique tuens, ait Articus illi—
Immemorem sponsæ cupidus quam mungit adulter!
Hæc tua tota fides, sic sic aliena ministras!
Erubuit nihil ausa palam, nisi mollia pacis
Verba, sed assuetis noctem complexibus egit—
Ah, harlot! squinting with lascivious brows
Upon a hapless wife's adulterous spouse,
Is this thy faith, to waste another's wealth.
The guilty fruit of perfidy and stealth!
She durst not be my foe in open light.
But in my foe's embraces spent the night.
Meanwhile, Marquard, Bishop of Augsburg, vicar of the Emperor in Italy, having put himself at the head of the Lombard league against the Viscontis, entered their territories with the German troops, and was committing great devastations. But the brothers of Milan turned out, beat the Bishop, and took him prisoner. It is evident, from these hostilities of the Emperor's vicar against the Viscontis, that Petrarch's embassy to Prague had not had the desired success. The Emperor, it is true, plainly told him that he had no thoughts of invading Italy in person. And this was true; but there is no doubt that he abetted and secretly supported the enemies of the Milan chiefs. Powerful as the Visconti were, their numerous enemies pressed them hard; and, with war on all sides, Milan was in a critical situation. But Petrarch, whilst war was at the very gates, continued retouching his Italian poetry.
At the commencement of this year, 1356, he received a letter from Avignon, which Socrates, Lælius, and Guido Settimo had jointly written to him. They dwelt all three in the same house, and lived in the most social union. Petrarch made them a short reply, in which he said, "Little did I think that I should ever envy those who inhabit Babylon. Nevertheless, I wish that I were with you in that house of yours, inaccessible to the pestilent air of the infamous city. I regard it as an elysium in the midst of Avernus."
