The insurrection next spread to Thessaly; and at last even to Macedonia, from the premature and atrocious violence of the Pacha of Salonika. Apprehending a revolt, he himself drew it on, by cutting off the heads of the Christian merchants and clergy (simply as a measure of precaution), and enforcing his measures on the peasantry by military execution. Unfortunately, from its extensive plains, this country is peculiarly favorable to the evolutions of the Turkish cavalry; the insurgents were, therefore, defeated in several actions; and ultimately took refuge in great numbers amongst the convents on Mount Athos, which also were driven into revolt by the severity of the Pacha. Here the fugitives were safe from the sabres of their merciless pursuers; but, unless succored by sea, ran a great risk of perishing by famine. But a more important accession to the cause of independence, within one month from its first outbreak in the Morea, occurred in the Islands of the Archipelago. The three principal of these in modern times, are Hydra, Spezzia, and Psarra. [Footnote: Their insignificance in ancient times is proclaimed by the obscurity of their ancient names--Aperopia, Tiparenus, and Psyra.] They had been colonized in the preceding century, by some poor families from Peloponnesus and Ionia. At that time they had gained a scanty subsistence as fishermen. Gradually they became merchants and seamen. Being the best sailors in the Sultan's dominions, they had obtained some valuable privileges, amongst which was that of exemption from Turkish magistrates; so that, if they could not boast of _autonomy_, they had at least the advantage of executing the bad laws of Turkish imposition by chiefs of their own blood. And they had the further advantage of paying but a moderate tribute to the Sultan. So favored, their commerce had flourished beyond all precedent. And latterly, when the vast extension of European warfare had created first-rate markets for grain, selecting, of course, those which were highest at the moment, they sometimes doubled their capitals in two voyages; and seven or eight such trips in a year were not an unusual instance of good fortune. What had been the result, may be collected from the following description, which Mr. Gordon gives us, of Hydra: "Built on a sterile rock, which does not offer, at any season, the least trace of vegetation, it is one of the best cities in the Levant, and _infinitely superior to any other in Greece_; the houses are all constructed of white stone; and those of the aristocracy--erected at an immense expense, floored with costly marbles, and splendidly furnished--_might pass for palaces even in the capitals of Italy_. Before the revolution, poverty was unknown; all classes being comfortably lodged, clothed, and fed. Its inhabitants at this epoch exceeded twenty thousand, of whom four thousand were able-bodied seamen."
