Ariantas

Ariantas (Scythian: *Ariyā̆nta;^[1] Ancient Greek: Άριάντας, romanized: Ariantás; Latin: Ariantas) was a king of the Scythians, who, in order to learn the population of his people, commanded every Scythian to bring him one arrow-head. With these arrow-heads he made an enormous brazen or copper vessel,^[2] which was set up in a place called "Exampaeus", between the rivers Borysthenes and Hypanis. This was important because the total number of Scythians had always been difficult to determine, because of their nomadic behaviors.^[3]

We know of Ariantas only from one single passage in Herodotus.^[4]
