But the knight of the early middle ages was much more than a professional soldier. He was the civil servant of that day. He was the judge of his community and he was the chief of police. He caught the highwaymen and protected the wandering pedlars who were the merchants of the eleventh century. He looked after the dikes so that the countryside should not be flooded (just as the first noblemen had done in the valley of the Nile four thousand years before). He encouraged the Troubadours who wandered from place to place telling the stories of the ancient heroes who had fought in the great wars of the migrations. Besides, he protected the churches and the monasteries within his territory, and although he could neither read nor write, (it was considered unmanly to know such things,) he employed a number of priests who kept his accounts and who registered the marriages and the births and the deaths which occurred within the baronial or ducal domains.
