45. Thus fared the fleet; and meanwhile Mardonios and the land-army while encamping in Macedonia were attacked in the night by the Brygian Thracians, and many of them were slain by the Brygians and Mardonios himself was wounded. However not even these escaped being enslaved by the Persians, for Mardonios did not depart from that region until he had made them subject. But when he had subdued these, he proceeded to lead his army back, since he had suffered great loss with his land-army in fighting against the Brygians and with his fleet in going round Athos. So this expedition departed back to Asia having gained no honour by its contests. 46. In the next year after this Dareios first sent a messenger to the men of Thasos, who had been accused by their neighbours of planning revolt, and bade them take away the wall around their town and bring their ships to Abdera. The Thasians in fact, as they had been besieged by Histiaios the Milesian and at the same time had large revenues coming in, were using their money in building ships of war and in surrounding their city with a stronger wall. Now the revenues came to them from the mainland and from the mines: from the gold-mines in Scapte Hyle 31 there came in generally eighty talents a year, and from those in Thasos itself a smaller amount than this but so much that in general the Thasians, without taxes upon the produce of their soil, had a revenue from the mainland and from the mines amounting yearly to two hundred talents, and when the amount was highest, to three hundred.. 47. I myself saw these mines, and by much the most marvellous of them were those which the Phenicians discovered, who made the first settlement in this island in company with Thasos; and the island had the name which it now has from this Thasos the Phenician. These Phenician mines are in that part of Thasos which is between the places called Ainyra and Koinyra and opposite Samothrake, where there is a great mountain which has been all turned up in the search for metal. Thus it is with this matter: and the Thasians on the command of the king both razed their walls and brought all their ships to Abdera. 48. After this Dareios began to make trial of the Hellenes, what they meant to do, whether to make war with him or to deliver themselves up. He sent abroad heralds therefore, and appointed them to go some to one place and others to another throughout Hellas, bidding them demand earth and water for the king. These, I say, he sent to Hellas; and meanwhile he was sending abroad other heralds to his own tributary cities which lay upon the sea-coast, and he bade them have ships of war built and also vessels to carry horses..
