Histories

The Scythians and Persians burst into their land, agitating them; and from there, the Scythians led the Persians into the country of the Man-eaters, agitating them too; from there, they drew off into the country of the Neuri and, agitating them also, fled to the Agathyrsi.

But the Agathyrsi, seeing their neighbors fleeing panic-stricken at the Scythians' approach, before the Scythians could break into their land sent a herald to forbid them to set foot across their borders, warning the Scythians that if they tried to break through they would have to fight with the Agathyrsi first.
