Some other manpower figures, nearer to the Bronze Age: in the classical
period the city-states Athens and Argos could each field about 8,000
hoplites, citizen soldiers who provided their own equipment and were in the
upper reaches of their society.
At various times Athens was able to man a fleet of 200 triremes with crews
totalling about 40,000, drawing on the lower classes for the rowers.
