The other chief motive for condensing or obscuring his text has a more subtle foundation. Indeed, we are surprised that we should possess so great a collection of recipes, representing to him who could use them certain commercial and social value. The preservation of Apicius seems entirely accidental. Experienced cooks were in demand in Apicii times; the valuation of their ministrations increased proportionately to the progress in gastronomy and to the prosperity of the nation. During Rome's frugal era, up to 200 B.C. the primitive cooks were just slaves and household chattels; but the development of their trade into an art, stimulated by foreign precepts, imported principally from Greece, Sicily and Asia Minor, opened up to the practitioners not only the door to freedom from servitude but it offered even positions of wealth with social and political standing, often arousing the envy, satire, criticism of bona-fide politicians, journalists, moralists, satirists and of the ever-present hordes of parasites and hangers-on. Some cooks became confidants, even friends and advisors of men in high places, emperors, (cf. life of Vitellius) and through their subtle influence upon the mighty they may have contributed in no mean measure to the fate of the nation. But such invisible string-pullers have not been confined to those days alone. (Take Rasputin! Take the valet to William I, reputed to have had more "say" than the mighty Bismarck, who, as it developed, got "the air" while the valet died in his berth.) Such being the case, what potential power reposed in a greasy cookery manuscript! And, if so, why bare such wonderful secrets to Tom, Dick and Harry?
