Plutarch: Lives of the noble Grecians and Romans

As geographers, Sosius, crowd into the edges of their maps parts of the world which they do not know about, adding notes in the margin to the effect, that beyond this lies nothing but sandy deserts full of wild beasts, unapproachable bogs, Scythian ice, or a frozen sea, so, in this work of mine, in which I have compared the lives of the greatest men with one another, after passing through those periods which probable reasoning can reach to and real history find a footing in, I might very well say of those that are farther off, Beyond this there is nothing but prodigies and fictions, the only inhabitants are the poets and inventors of fables; there is no credit, or certainty any farther.

Both warriors; that by all the world’s allowed.
