'In what far distant region of the sky Hushed in silence sleep ye when 'tis calm?'
The attempt to draw out Voltaire upon the tour to the Hebrides, which Boswell and Johnson had been vaguely talking over, produced only the rather sarcastic query if he wished him to accompany them, with a look 'as if I had talked of going to the North Pole.' Of his visit to the wild philosopher, as he styles Rousseau, we have no notice, beyond the general remark that they had agreed to differ alike in politics and religion, but that there were points _où nos âmes sont unies_. The feudal dogmas of Boswell and his rigid adherence to his pet idea of 'the grand scheme of subordination' were of course not likely to be pleasing to the sceptical _aqua fortis_ of the sombre Genevese, with his belief in the fraternity of mankind and the greatness of the untutored Indian.
Boswell crossed the Alps, and either then or upon his homeward journey visited Bologna, Venice, and Mantua. He passed through Rome and, unknown to either, may have met Gibbon in the Eternal City into whose mind, some weeks before, 'as I sat musing among the ruins of the Capitol while the bare-footed friars were singing vespers in the Temple of Jupiter,' had started the idea of writing the _Decline and Fall_. In the city he met Andrew Lumsden, the Secretary of Prince Charles Edward, but we are not informed if the young Jacobite of five, who had prayed for the exiled family now sought any opportunity of making himself known to the object of his devotion. Naples brought him into the more congenial society of Wilkes with whom, he says, he 'enjoyed many classical scenes with peculiar relish.' When Churchill had died at Boulogne in the arms of Wilkes, the latter had retired to Naples to inscribe his sorrow 'in the close style of the ancients' upon an urn of alabaster which had been the gift of Winckelmann, and in that city now he was, as the literary executor, preparing annotations on the works of Churchill. Boswell managed with his curious want of tact in such matters, fitting the man who could suggest cards to a dying friend with an uneasy conscience, to hint that the poet had 'bounced into the regions below,' and to render the _Il Bruto Inglese_, by which the papers of the land referred to Wilkes and liberty, by a version significant of the notorious ugliness of his gay acquaintance. Naples, as with Milton, was the limit of his tour, and from it he returned to Rome. He reached that city in April 1765, and dispatched a letter to Rousseau, then 'living in romantick retirement' in Switzerland, requesting his promised introduction to the Corsican general, 'which if he refused, I should certainly go without it, and probably be hanged as a spy.' The wild philosopher was as good as his word, and the letter met the traveller at Florence. 'The charms of sweet Siena detained me no longer than they should have done, I required the hardy air of Corsica to brace me, after the delights of Tuscany,' an enigmatical turn of expression upon which light is thrown later, when we discuss the love affairs of Boswell, by a reference to a dark-eyed 'signora' on whom the tender traveller had glanced. At Leghorn he was within one day's sail of Corsica.
