Note 4 — Chapter I

"If the Turks had possessed this bulwark of Christendom (Vienna), I do not conceive what could have hindered them from being masters immediately of Austria, and all its depending provinces; nor, in another year, of all Italy, or of the southern provinces of Germany, as they should have chosen to carry on their invasion, or of both in two or three years' time; and how fatal this might have been to the rest of Christendom, or how it might have enlarged the Turkish dominions, is easy to conjecture."—Sir W. Temple, Works, iii. 393, edit. 1814.
