own instant ruin. In speculating on the causes of the extraordinary terror which the Turks once inspired, it is amusing, and illustrative of the revolutions worked by time, to find it imputed, in the first place, to superior discipline; for, if their discipline was imperfect, they had, however, a _standing_ army of Janissaries, whilst the whole of Christian Europe was accustomed to fight merely summer campaigns with hasty and untrained levies; a second cause lay in their superior finances, for the Porte had a regular revenue, when the other powers of Europe relied upon the bounty of their vassals and clergy; and, thirdly, which is the most surprising feature of the whole statement, the Turks were so far ahead of others in the race of improvement, that to them belongs the credit of having first adopted the extensive use of gunpowder, and of having first brought battering-trains against fortified places. To his artillery and his musketry it was that Selim the Ferocious (grandson of that Sultan who took Constantinople) was indebted for his victories in Syria and Egypt. Under Solyman the Magnificent (the well-known contemporary of the Emperor Charles Y.) the crescent is supposed to have attained its utmost altitude; and already for fifty years the causes had been in silent progress which were to throw the preponderance into the Christian scale. In the reign of his son, Selim the Second, this crisis was already passed; and the battle of Lepanto, in 1571, which crippled the Turkish navy in a degree never wholly recovered, gave the first overt signal to Europe of a turn in the course of their prosperity. Still, as this blow did not equally affect the principal arm of their military service, and as the strength of the German empire was too much distracted by Christian rivalship, the _prestige_ of the Turkish name continued almost unbroken until their bloody overthrow in 1664, at St. Gothard, by the imperial General Montecuculi. In 1673 they received another memorable defeat from Sobieski, on which occasion they lost twenty-five thousand men. In what degree, however, the Turkish Samson had been shorn of his original strength, was not yet made known to Europe by any adequate expression, before the great catastrophe of 1683. In that year, at the instigation of the haughty vizier, Kara Mustafa, the Turks had undertaken the siege of Vienna; and great was the alarm of the Christian world. But, on the 12th of September, their army of one hundred and fifty thousand men was totally dispersed by seventy thousand Poles and Germans, under John Sobieski--"He conquering _through_ God, and God by him." [Footnote: See the sublime Sonnet of Chiabrora on this subject, as translated by Mr. Wordsworth.] Then followed the treaty of Carlovitz, which stripped the Porte of Hungary, the Ukraine, and other places; and "henceforth" says Mr. Gordon, "Europe ceased to dread the Turks; and began even to look upon their existence as a necessary element of the balance of power
