The Histories · 4.142

Thus the Persians escaped, and the Scythians in their search missed the Persians the second time also: and their judgment of the Ionians is that on the one hand, if they be regarded as free men, they are the most worthless and cowardly of all men, but on the other hand, if regarded as slaves, they are the most attached to their master and the least disposed to run away of all slaves. This is the reproach which is cast against the Ionians by the Scythians.
