curved westward along the coast of northern Africa, through Spain, like one of their own scimitars, threatening all Christendom. Indeed, the Arab invasion stands unparalleled in history for its rapidity and extent.

| THE SARACEN EMPIRE AT ITS HEIGHT, ABOUT 715 A.D. |
The one great obstacle in the way was the Christian, or Roman, empire with its center at Constantinople. Muaviah, the Emir of Syria, was the first to perceive that nothing could be done against the empire until the Arabs had wrested from it the command of the sea. Accordingly he set about building a great naval armament. In 649 this fleet made an attack on Cyprus but was defeated. The following year, however, it took an important island, Aradus, off the coast of Syria, once a stronghold of the Phœnicians, and sacked it with savage barbarity. An expedition sent from Constantinople to recover Alexandria was met by this fleet and routed. This first naval victory over the Christians gave the Saracens unbounded confidence in their ability to fight on the sea. They sailed into the Ægean, took Rhodes, plundered Cos, and returned loaded with booty. Muaviah, elated with these successes, planned a great combined land and water expedition against the Christian capital.
At this point it is worth pausing to consider what the fighting ship of this period was like. As we have seen in the preceding chapter the Roman navy sank into complete decay. At the end of the fourth century there was practically no imperial navy in existence. The conquest of the Vandals by Belisarius in the sixth century involved the creation of a fleet, but when that task was over the navy again disappeared until the appearance of the Arabs compelled the building of a new imperial fleet. The small provincial squadrons then used to patrol the coasts were by no means adequate to meet the crisis.
The warships of this period were called "dromons," a term that persists even in the time of the Turkish invasion eight centuries later. The word means "fast sailers" or "racers." The dromon was not the low galley of the later Middle Ages but a two-banked ship, probably quite as large as the Roman quinquereme, carrying a complement of about 300 men. Amidships was built a heavy castle or redoubt of timbers, pierced with loopholes for archery. On the forecastle rose a kind of turret, possibly revolving, from which, after Greek fire was invented, the tubes or primitive cannon projected the substance on the decks of the enemy. The dromon had two masts, lateen rigged, and between thirty and forty oars to a side.
There were two classes of dromons, graded according to size, and a third class of ship known as the "pamphylian," which was apparently of a cruiser type, less cumbered with superstructure. In addition there were small scout and dispatch boats of various shapes and sizes.
Both Christian and Saracen fought with these kinds of warships. Apparently the Arabs simply copied the vessels they found already in use by their enemies, and added no new device of their own.

| EUROPE'S EASTERN FRONTIER |
In 655 Muaviah started his great double invasion against Constantinople. He sent his fleet into the Ægean, while he himself with an army tried to force the passes of the Taurus mountains. Before the Arab fleet had gone far it met the Christian fleet, commanded by the Emperor himself, off the town of Phaselis on the southwestern coast of Asia Minor. A great battle followed. The Christian emperor, Constantine II, distinguished himself by personal courage throughout the action, but the day went sorely against the Christians. At last the flagship was captured and he himself survived only by leaping into a vessel that came to his rescue while his men fought to cover his escape. It was a terrible defeat, for 20,000 Christians had been killed and the remnants of their fleet were in full retreat. But the Saracens had bought their victory at such a price that they were themselves in no condition to profit by it, and the naval expedition went no further. Meanwhile Muaviah had not succeeded in forcing the Taurus with his army, so that the grand assault came to nothing after all.
The following year the murder of the Caliph brought on a civil war among the Saracens, in consequence of which Muaviah arranged a truce with Constantine. The latter was thus enabled to turn his attention to the beating back of the Slavs in the east and the recovery of imperial possessions in the west, notably the city and province of Carthage. During the last of these campaigns he was killed by a slave.
The death of this energetic and able ruler seemed to Muaviah the opportunity to begin fresh operations against the Christian empire. Three great armies invaded the territory of the Cross. One plundered Syracuse, another seized and fortified a post that threatened the existence of Carthage, a third pushed to the shores of the Sea of Marmora. These were, however, only preliminary to the grand assault on the capital itself.
In 673 a great Arab armada forced the Hellespont and captured Cyzicus. With this as a base, the fleet landed an army on the northern shore of the Sea of Marmora. By these means Constantinople was invested by land and sea. But the great walls proved impregnable against the attacks of the army, and the Christian fleet, sheltered in the Golden Horn, was able to sally out from time to time and make successful raids on detachments of the Saracen ships. This state of affairs continued for six months, after which Muaviah retired with his army to Cyzicus, leaving a strong naval guard to hold the straits.
The next spring Muaviah again landed his army on the European side and besieged the city for several months. The second year's operations were no more successful than the first, and again the Arab force retired to Cyzicus for the winter.
The Arab commander was determined to stick it out until he had forced the surrender of the city by sheer exhaustion, but his plan had a fatal error. During the winter months the land blockade was abandoned, with the result that supplies for the next year's siege were readily collected for the beleaguered city. Emperor and citizens alike rose to the emergency with a spirit of devotion that burned brighter with every year of the siege. Meanwhile the Christians of the outlying provinces of Syria and Africa were also fighting stubbornly and with considerable success against the enemy. The year 676 passed without any material change in the situation.

| CONSTANTINOPLE AND VICINITY |
During the siege a Syrian architect named Callinicus is said to have come to Constantinople with a preparation of his own invention, "Greek fire," which he offered the Emperor for use against the Saracen. This, according to one historian, "was a semi-liquid substance, composed of sulphur, pitch, dissolved niter, and petroleum boiled together and mixed with certain less important and more obscure substances. … When ejected it caught the woodwork which it fell and set it so thoroughly on fire that there was no possibility of extinguishing the conflagration. It could only be put out, it is said, by pouring vinegar, wine, or sand upon it."[1]
[Footnote 1: The Art of War, Oman, p. 546.]
Constantine IV, the Emperor, was quick to see the possibilities of the innovation and equipped his dromons with projecting brass tubes for squirting the substance upon the enemy's ships. These are sometimes referred to as "siphons," but it is not clear just how they were operated. One writer[2] is of the opinion that something of the secret of gunpowder had been obtained from the East and that the substance was actually projected by a charge of gunpowder; in short, that these "siphons" were primitive cannon. In addition to these tubes other means were prepared for throwing the fire. Earthenware jars containing it were to be flung by hand or arbalist, and darts and arrows were wrapped with tow soaked in the substance.

The Christian fleet was no match for the Saracen in numbers, but Constantine pinned his faith on the new invention. Accordingly, during the fourth year of the siege, 677, he boldly led his fleet to the attack. We have no details of this battle beyond the fact that the Greek fire
