Ἅμιπποι

According to Isaeus¹ [this means] those campaigning with horses. But others say that certain horses are yoked together and someone drives them, mounted on one and leading the other alongside; and these are called horse-attached. But Thucydides and Xenophon make it clear that the horse-attached were infantrymen.² And perhaps those deployed together with the cavalry are scouts of some kind.
