Res Gestae

Around these farthest and most distant marshes live numerous nations, differing in the variety of their languages and customs: the Ixomatae, Maeotae, Iazyges, Roxolani, Halani, Melanchlaenae, and with the Geloni, the Agathyrsi, in whose country an abundance of the stone called adamant[*](adamas,untamable,unbreakable is variously applied to a kind of steel, and to diamonds and like stones.) is found; and farther beyond are other peoples, who are wholly unknown, since they are the remotest of all men.
