29. While these events were taking place, the Roman envoys,¹ Gaius Popilius, Gaius Decimius, and Gaius Hostilius, set out from Chalcis in three five-banked ships and on arriving at Delos found there forty Macedonian scout-ships and five five-bankers of King Eumenes. [2] The holiness of the temple and the island kept them all from harm. And so the Roman, the Macedonian, and Eumenes' sailors mingled in the temple under the truce provided by the sacredness of the place. [3] Whenever signals came from the lookouts that any freight-ships were passing out at sea, Antenor, Perseus' officer, would himself pursue with some ships, while others of his ships were distributed among the Cyclades, and either sank or plundered every ship not sailing for Macedonia. [4] Popilius would come to the rescue with what ships he had either of his own or Eumenes'; but the Macedonians would evade him by sailing at night mostly in groups of two or three ships.

[5] At about this same time, the envoys from Macedonia and Illyria [6??] arrived together at Rhodes, and weight was lent their words not only by the arrival of the scoutships roaming all around the Cyclades and the Aegean Sea, but also by the very fact of the combination between the kings Perseus and Gentius, and the rumour of the arrival of the Gauls in great numbers both of infantry and cavalry. [7] Since, then, the boldness of Dinon and Polyaratus, who sided with [p. 187]Perseus, was on the increase, not only was a cordial² response given to the kings, but the flat statement was made that the Rhodians would by their influence bring an end to the war, and that therefore the kings [8??] themselves should make up their minds calmly to accept peace.³
