The conquest of Otranto was the last of the conquests of him who rightly stands out in Ottoman history as pre-eminently the Conqueror. The second Mahomet, he who completed the conquest of Christian Asia by the taking of Trebizond, who crowned the work of Ottoman conquest in Europe by the taking of Constantinople, who by the taking of Euboia dealt the heaviest blow to the Venetian power in the Ægæan, who brought under his power, as a gleaning after the vintage, the Frank lordship of Attica and the Greek lordship of Peloponnêsos, in his last days stretched forth his hand to vex Western Europe as he had so long vexed Eastern Europe and what was left of Christian Asia. He was in truth attacking both at the same time; he won Otranto almost at the moment when he was beaten back from Rhodes. Each scene of his warfare illustrates the nature of the Ottoman power at that moment, how it was by the hands of her own apostate sons that Christendom was brought into bondage. Against Rhodes the infidel host was led by a Greek, against Otranto by an Albanian, both renegades or sons of renegades. And under the first Ferdinand of Aragon such was the state of things in the land which had once been ruled by good King William that soldiers of the Neapolitan King were willing to pass into the service of the Turk. Nay, the inhabitants in general seemed ready to believe the Turk's promises and to accept his dominion as likely to be milder than that of their own stranger king. The invader was his own worst enemy. A contemporary writer witnesses that the prisoners taken by Achmet _Break-Tooth_--such is said to be the meaning of his surname _Giédek_--pointed out to him that by his cruelties at Otranto he was losing for his master a province which otherwise might have been won with little effort.
But happily things took another turn. Otranto was in the Western world what Kallipolis--the Kallipolis of the Thracian Chersonêsos--had been in the Eastern. It was the first foothold of the barbarian, the gate by which he seemed likely to open his way to the possession of the central peninsula of Europe, as he had by the gate of Kallipolis opened his way to the possession of the eastern peninsula. Otranto was the last of the conquests of the great Conqueror; what if he had been longer-lived? what if the second Bajazet had deserved the name of Thunderbolt like the first? Would the threat of the first Sultan have been carried out, and would the Turk have fed his horse on the high altar of Saint Peter's? The eastern peninsula fell by internal division, and the central peninsula, as his very entrance into it shows, was fully as divided as the eastern. The French conquests presently showed how little prepared Italy was to withstand a vigorous attack, and Mahomet the Conqueror would have been another kind of enemy from Charles the Eighth. But all such dangers were warded off. The Turk still showed himself once and again in northern Italy, but only as a momentary plunderer. Otranto remained his only conquest on Italian ground, and that a conquest held for thirteen months only. Alfonso, who bears so unfavourable a character from other sides, must be at least allowed the merit of winning back the lost city for his father's realm. Otranto, and Otranto alone of Italian cities, belongs to, and heads, the list on which we inscribe the names of Buda and Belgrade and Athens and Sofia, on which it may now inscribe the names of Arta and Larissa, but from which hapless Jôannina and twice-forsaken Parga are still for a while shut out.
