46. But the whole sea, all around, is full of mists and shoals, and is sweeter than seas in general, because by the evaporation of moisture the air is often thick and dense, and its waters are tempered by the immensity of the rivers which fall into it; and it is full of shifting shallows, because the number of the streams which surround it pour in mud and lumps of soil. 47. And it is well known that fish flock in large shoals to its most remote extremities that they may spawn and rear their young more healthfully, in consequence of the salubrity of the water; while the hollow caverns, which are very numerous there, protect them from voracious monsters. For nothing of the kind is ever seen in this sea, except some small dolphins, and they do no harm. 48. Now the portions of the Black Sea which are exposed to the north wind are so thoroughly frozen that, while the rivers, as it is believed, cannot continue their course beneath the ice, yet neither can the foot of beast or man proceed firmly over the treacherous and shifting ground; a fault which is never found in a pure sea, but only in one of which the waters are mingled with those of rivers. We have digressed more than we had intended, so now let us turn back to what remains to be told. 49. Another circumstance came to raise Julian's present joy, one which indeed had been long expected, but which had been deferred by all manner of delays. For intelligence was brought by Agilo and Jovius, who was afterwards quæstor, that the garrison of Aquileia, weary of the length of the siege, and having heard of the death of Constantius, had opened their gates and come forth, delivering up the authors of the revolt; and that, after they had been burnt alive, as has been related, the rest had obtained pardon for their offences. IX. § 1. But Julian, elated at his prosperity, began to aspire to greatness beyond what is granted to man: amid continual dangers he had learnt by experience that propitious fortune held out to him, thus peacefully governing the Roman world, a cornucopia as it were of human blessings and all kinds of glory and success: adding this also to his former titles of victory, that while he alone held the reins of empire he was neither disturbed by intestine commotions, nor did any barbarians venture to cross his frontiers; but all nations, eager at all times to find fault with what is past, as mischievous and unjust, were with marvellous unanimity agreed in his praises. 2. Having therefore arranged with profound deliberation all the matters which were required either by the circumstances of the state or by the time, and, having encouraged the soldiers by repeated harangues and by adequate pay to be active in accomplishing all that was to be done, Julian, being in great favour with all men, set out for Antioch, leaving Constantinople, which he had greatly strengthened and enriched; for he had been born there, and loved and protected it as his native city.
