All these persons now went on their way to <a class="linkToPlace" target="_blank" href="/place?placename=Macedonia&groupId=723&placeId=428">Macedonia</a>, while Pantauchus remaining behind beside the young man kept on reminding him and urging him not to be behindhand in his preparations, but to get all ready, and secure in due time places, towns, and allies.
He particularly requested him to prepare for war by sea, since, the Romans being quite unprepared in this respect on the coasts of Epirus and <a class="linkToPlace" target="_blank" href="/place?placename=Illyria&groupId=647&placeId=1186">Illyria</a>, he would with very little trouble in person and through his officers be able to carry out any maritime project he wished.
Genthius, then, convinced by those arguments, was occupied in preparing himself by land and sea.
Perseus, on the arrival in <a class="linkToPlace" target="_blank" href="/place?placename=Macedonia&groupId=723&placeId=428">Macedonia</a> of the envoys Genthius and the hostages, starting from his camp near the river Elpeius with all his cavalry, went to meet them all at <a class="linkToPlace" target="_blank" href="/place?placename=Dium&groupId=542&placeId=1019">Dium</a>
and on doing so took the oath of alliance in the presence of all the cavalry; for have particularly wished that the Macedonians should be aware of the co-operation of Genthius, thinking that the addition of this force to the scale would increase their confidence.
He next received the hostages, and handed over his own to Olympion. The most distinguished of these latter were Limnaeus the son of Polemocrates and Balacrus the son of Pantauchus.
Perseus next sent those who had come to get the money to <a class="linkToPlace" target="_blank" href="/place?placename=Pella&groupId=1089&placeId=1913">Pella</a> where they would receive it, and the envoys for <a class="linkToPlace" target="_blank" href="/place?placename=Rhodes&groupId=931&placeId=1665">Rhodes</a> he sent to Thessalonica to meet Metrodorus, ordering them to be in readiness to embark. He succeeded in inducing the Rhodians to join in the war.
After accomplishing this he sent as envoy to Eumenes Herophon, who had already served in that capacity, urging him not to neglect this opportunity, nor think that the arrogance and oppression of the Romans were confined to himself,
but to recognize clearly that if he did not at present also come to his assistance, either, as was best, by putting an end to the war, or, if not, by helping in it, he would soon experience the same fate.
