Tacitus is describing the invasion of Armenia by Iberian king Pharsmanes and the battles with Parthia. He mentions in this excerpt the connection of Iberians with the Argonauts ands the speech of Pharsmanes before the battle.
ტაციტუსი, ანალები წიგნი VI. ფარსმან, იბერიის მეფის მიერ სომხეთის დაპყრობა და პართიის უფლისწულთან ბრძოლა. აქვე აღწერილია იბერიელების კავშირი მედეასა და იაზონთან. ასევე აღწერილია ფარსმანის სიტყვა ბრძოლის წინ.
Of the petty chiefs Mithridates was the first to persuade Pharasmanes to aid his enterprise by stratagem and force, and agents of corruption were found who tempted the servants of Arsaces into crime by a quantity of gold. At the same instant the Iberians burst into Armenia with a huge host, and captured the city of Artaxata. Artabanus, on hearing this, made his son Orodes the instrument of vengeance. He gave him the Parthian army and despatched men to hire auxiliaries. Pharasmanes, on the other hand, allied himself with the Albanians, and procured aid from the Sarmatae, whose highest chiefs took bribes from both sides, after the fashion of their countrymen, and engaged themselves in conflicting interests. But the Iberians, who were masters of the various positions, suddenly poured the Sarmatae into Armenia by the Caspian route. Meanwhile those who were coming up to the support of the Parthians were easily kept back, all other approaches having been closed by the enemy except one, between the sea and the mountains on the Albanian frontier, which summer rendered difficult, as there the shallows are flooded by the force of the Etesian gales. The south wind in winter rolls back the waves, and when the sea is driven back upon itself, the shallows along the coast, are exposed.
Meantime, while Orodes was without an ally, Pharasmanes, now strengthened by reinforcements, challenged him to battle, taunted him on his refusal, rode up to his camp and harassed his foraging parties. He often hemmed him in with his picquets in the fashion of a blockade, till the Parthians, who were unused to such insults, gathered round the king and demanded battle. Their sole strength was in cavalry; Pharasmanes was also powerful in infantry, for the Iberians and Albanians, inhabiting as they did a densely wooded country, were more inured to hardship and endurance. They claim to have been descended from the Thessalians, at the period when Jason, after the departure of Medea and the children born of her, returned subsequently to the empty palace of Aeetes, and the vacant kingdom of Colchi. They have many traditions connected with his name and with the oracle of Phrixus. No one among them would think of sacrificing a ram, the animal supposed to have conveyed Phrixus, whether it was really a ram or the figure-head of a ship.
Both sides having been drawn up in battle array, the Parthian leader expatiated on the empire of the East, and the renown of the Arsacids, in contrast to the despicable Iberian chief with his hireling soldiery. Pharasmanes reminded his people that they had been free from Parthian domination, and that the grander their aims, the more glory they would win if victorious, the more disgrace and peril they would incur if they turned their backs. He pointed, as he spoke, to his own menacing array, and to the Median bands with their golden embroidery; warriors, as he said, on one side, spoil on the other.
Among the Sarmatae the general’s voice was not alone to be heard. They encouraged one another not to begin the battle with volleys of arrows; they must, they said, anticipate attack by a hand to hand charge. Then followed every variety of conflict. The Parthians, accustomed to pursue or fly with equal science, deployed their squadrons, and sought scope for their missiles. The Sarmatae, throwing aside their bows, which at a shorter range are effective, rushed on with pikes and swords. Sometimes, as in a cavalry-action, there would be alternate advances and retreats, then, again, close fighting, in which, breast to breast, with the clash of arms, they repulsed the foe or were themselves repulsed. And now the Albanians and Iberians seized, and hurled the Parthians from their steeds, and embarrassed their enemy with a double attack, pressed as they were by the cavalry on the heights and by the nearer blows of the infantry.
Meanwhile Pharasmanes and Orodes, who, as they cheered on the brave and supported the wavering, were conspicuous to all, and so recognised each other, rushed to the combat with a shout, with javelins, and galloping chargers, Pharasmanes with the greater impetuosity, for he pierced his enemy’s helmet at a stroke. But he could not repeat the blow, as he was hurried onwards by his horse, and the wounded man was protected by the bravest of his guards. A rumour that he was slain, which was believed by mistake, struck panic into the Parthians, and they yielded the victory.
Artabanus very soon marched with the whole strength of his kingdom, intent on vengeance. The Iberians from their knowledge of the country fought at an advantage. Still Artabanus did not retreat till Vitellius had assembled his legions and, by starting a report that he meant to invade Mesopotamia, raised an alarm of war with Rome.
