Edwyn Robert Bevan, 1911 Encyclopædia Britannica (1911)
“ The Persian monarchy was strong in its size, in the mere amount of men and treasure it could dispose of under a single hand; the Greek state was strong in its morale, in the energy and discipline of its soldiery. But the smallness of the single city-states and their unwillingness to combine prevented this superiority in quality from telling destructively upon the bulk of the Persian empire. The future belonged to any power that could combine the advantages of both systems, could make a state larger than the Greek polis, and animated by a spirit equal to that of the Greek soldier. ”
