The ordinary family, however, held, perhaps, twelve acres, and, as the land was arable, and the staple grain, it supported a dense rural population. The husbandmen who tilled this land were of the martial type, and, probably for that reason, though supremely gifted as administrators and soldiers, were ill-fitted to endure the strain of the unrestricted economic competition of a centralized society. Consequently their conquests had hardly consolidated before decay set in, a decay whose causes may be traced back until they are lost in the dawn of history.The Latins had little economic versatility; they lacked the instinct of the Greeks for commerce, or of the Syrians and Hindoos for manufactures. They were essentially land-owners, and, when endowed with the acquisitive faculty, usurers.
