Lothair by Benjamin Disraeli

The continuous gathering of what, in popular language, were styled the Garibaldi Volunteers, on the southern border of the papal territory in the autumn of 1867, was not the only or perhaps the greatest danger which then threatened the Holy See, though the one which most attracted its alarmed attention. The considerable numbers in which this assemblage was suddenly occurring; the fact that the son of the Liberator had already taken its command, and only as the precursor of his formidable sire; the accredited rumor that Ghirelli at the head of a purely Roman legion was daily expected to join the frontier force; that Nicotera was stirring in the old Neapolitan kingdom, while the Liberator himself at Florence and in other parts of Tuscany was even ostentatiously, certainly with impunity, preaching the new crusade and using all his irresistible influence with the populace to excite their sympathies and to stimulate their energy, might well justify the extreme apprehension of the court of Rome. And yet dangers at least equal, and almost as close, were at the same time preparing unnoticed and unknown.

In the mountainous range between Fiascone and Viterbo, contiguous to the sea, is a valley surrounded by chains of steep and barren hills, but which is watered by a torrent scarcely dry, even in summer; so that the valley itself, which is not inconsiderable in its breadth, is never without verdure, while almost a forest of brushwood formed of shrubs, which in England we should consider rare, bounds the natural turf and ascends sometimes to no inconsiderable height the nearest hills.
