Startled by this cruel disaster, Julian (as he had previously planned) instantly put 30,000 picked men under the command of the

v2.p.323
aforesaid Procopius, and joined to him with equal powers Sebastianus, formerly a military commander in Egypt, and now a count, with orders to keep for the present on this side of the Tigris and to watch carefully everywhere and see that nothing unexpected should happen on the unprotected side, such as he had heard had often occurred. And he gave the order that (if it could be done to greater advantage) they should join King Arsaces, march with him through Corduene[*](Cf. xviii. 6, 20; modern Turkestan.) and Moxoëne,[*](In Armenia.) lay waste in passing by Chiliocomum, a fruitful region of Media,[*](It was really in Assyria.) and other places, and meet him while he was still in Assyria, so as to aid him in cases of necessity.

After these arrangements had thus been made, he himself feigned a march across the Tigris, an expedition for which he had also ordered supplies to be carefully prepared, but then turned to the right and, after passing a quiet night, called next morning for the mount which he usually rode. And when the horse, called Babylonius, was brought to him, it was laid low by a missile from the artillery, and as it rolled on the ground in unbearable pain, it scattered about its ornaments, which were adorned with gold and precious stones. Delighted by this omen, Julian cried out amid expressions of joy from the bystanders, that Babylon had fallen to the ground, stripped of all its adornments.

Then delaying for a time, in order to confirm the omen by favourable signs from victims, he came to the fortified camp of Davana at the source of the river Belias, a tributary of the Euphrates. Here we rested and took food, and on the following day arrived at Callinicum, a strong fortress, and most welcome because of its

v2.p.325
rich trade. There, on the twenty-seventh of March, the day on which at Rome the annual procession in honour of the Mother of the Gods takes place, and the carriage in which her image is carried is washed, as it is said, in the waters of the Almo, he celebrated the usual rites in the ancient fashion and spent the night in peaceful sleep, happy and full of confidence.

The next day he marched on from there along the brow of the river-banks, since the waters were rising from streams flowing in on all sides, and kept on with his armed force until he came to an outpost, where he encamped. There the princes of the Saracen nations as suppliants on bended knees presented him with a golden crown and did obeisance to him as lord of the world and of its peoples; and they were gladly received, since they were adapted for guerilla warfare.

And while he was giving them audience his fleet arrived, equal to that of the mighty king Xerxes, under the command of the tribune Constantianus and Count Lucillianus; and the broad Euphrates was almost too narrow for it, consisting as it did of a thousand cargo-carriers of varied construction, and bringing an abundance of supplies, weapons, and also siege-engines; there were besides fifty warships and an equal number which were needed for making bridges.

What I have just said suggests that I should, as briefly as my modest ability permits, give a

v2.p.327
concise description of engines of this kind, for the benefit of those who are unacquainted with them; and I shall first explain the form of the ballista.[*](See illustrations between pp. 328 and 329. These give a general idea of the scorpion and the ram, although they do not contain all the features of Ammianus’ description.)

Between two posts along, strong iron baris fastened, and projects like a great ruler; from its smooth, rounded surface, which in the middle is highly polished, a squared staff extends to a considerable distance, hollowed out along its length with a narrow groove, and bound there with a great number of twisted cords. To this two wooden rollers are very firmly attached, and near one of them stands the gunner who aims the shot. He carefully places in the groove of the projecting iron bar a wooden arrow, tipped with a great iron point. When this is done, strong young men on both sides quickly turn the rollers and the cords.

When its point has reached the outermost ropes, the arrow, driven by the power within, flies from the ballista out of sight,[*](Its action is like that of a huge crossbow. The arrow is drawn back by a cord fastened to the ropes on the rollers. When the catch is released, these ropes drive out the arrow.) sometimes emitting sparks because of the excessive heat. And it often happens that before the weapon is seen, the pain of a mortal wound makes it felt.

The scorpion, which is now-a-days called the wild ass, has the following form. Two posts of oak or holm-oak are hewn out and slightly bent, so that they seem to stand forth like humps. These are fastened together like a sawing-machine and bored through on both sides with fairly large holes. Between them, through the holes, strong ropes are bound, holding the machine together, so that it may not fly apart.

From the middle of these ropes a wooden arm rises obliquely, pointed upward like the

v2.p.329
pole of a chariot,[*](I.e. when the horses are not harnessed to it.) and is twined around with cords in such a way that it can be raised higher or depressed. To the top of this arm, iron hooks are fastened, from which hangs a sling of hemp or iron. In front of the arm is placed a great cushion of hair-cloth stuffed with fine chaff, bound on with strong cords, and placed on a heap of turf or a pile of sundried bricks; for a heavy machine of this kind, if placed upon a stone wall, shatters everything beneath it by its violent concussion, rather than by its weight.

Then, when there is a battle, a round stone is placed in the sling and four young men on each side turn back the bar with which the ropes are connected and bend the pole almost flat. Then finally the gunner, standing above, strikes out the pole-bolt, which holds the fastenings of the whole work, with a strong hammer, thereupon the pole is set free, and flying forward with a swift stroke, and meeting the soft hair-cloth, hurls the stone, which will crush whatever it hits.

And the machine is called tormentum as all the released tension is caused by twisting (torquetur); and scorpion, because it has an upraised sting; modern times have given it the new name onager, because when wild asses are pursued by hunters, by kicking they hurl back stones to a distance, either crushing the breasts of their pursuers, or breaking the bones of their skulls and shattering them.

Now we shall come to the ram. A tall fir or mountain ash is selected, to the end of which is fastened a long, hard iron; this has the appearance of a projecting ram’s head, and it is this shape which

v2.p.331
has given the machine its name. This is suspended between ironbound beams running across on both sides, so that it hangs from a third beam like the pan of a balance. Then a number of men, as great as the length of the pole permits, draw it back and then shove it forward again with powerful blows, just as a ram charges and retreats, to break everything in its way. As this is renewed with the force of a repeated stroke of lightning,[*](The ancients believed that a stroke of lightning returned to the sky, doing damage as it came and as it went. Cf. Lucan, i, 156.) buildings are cracked and shattered as the structure of their walls is destroyed.

If this kind of engine is worked with full vigour, the strongest cities, after their walls have been stripped of defenders, are laid open, and the siege is thus brought to an end.

In place of these devices of rams, which, because they are now so frequent, are in less esteem, a machine is made, well known to the historians, which we Greeks call helepolis.[*](City-taker. The descriptions of Diod. xx. 48 and 91, and Athen. v. p. 206 d, are of a more powerful machine, including lofty towers.) It was through the constant employment of this engine that Demetrius, the son of King Antigonus, after taking Rhodes and other cities gained the name of Poliorcetes.[*](Besieger of cities.)

It is built in the following manner: a huge mantlet[*](Or tortoise-shed.) is constructed of strong planks of great length fastened together with iron nails, and covered with ox-hides and hurdles of green twigs; and over these is spread mud, in order to protect it from fire and falling missiles.

On its front side are set very sharp,[*](Cf. falces praeacutae, Caes., B.G. iii. 14, 5, and Class. Journal, vi. (1910), pp. 133 f.) three-pronged spear-points, of

v2.p.333
the form which our painters and sculptors give to thunderbolts, made heavy with iron weights, so that whatever it attacks it shatters with the projecting points.

This powerful mass is guided by numerous soldiers within by means of wheels and ropes, and by their united efforts is brought up to the weaker part of the walls; and unless the strength of the defenders above is too great, it shatters the walls and opens great breaches.

But fire-darts (a kind of missile) are made in this form: the shaft is of reed, and between this and the point is a covering of bands of iron; it looks like a woman’s distaff for making linen threads. It is skilfully hollowed out on the lower side with many openings, and in the cavity fire and some inflammable matter are placed.

And if it is shot slowly from a somewhat loose bow (for it is extinguished by too swift a flight) and has stuck anywhere, it burns persistently, and water poured upon it rouses the fire to still greater heat; and there is no way of extinguishing it except by sprinkling it with dust. So much for mural engines, of which I have described only a few. Now let us return to the course of our narrative.
