History does not usually busy itself with little men and small facts, and is therefore often obscure, unprecise, vague, tiresome. I believe that if some day I deserve praise, it will be because I have tried to show that everything has value and importance; that all phenomena interweave, act, and react upon each other--economic changes and political revolutions, costumes, ideas, the family and the state, land-holding and cultivation. There are no insignificant events in history; for the great events, like revolutions and wars, are inevitably and indissolubly accompanied by an infinite number of slight changes, appearing in every part of a nation: if in life there are men without note, and if these make up the great majority of nations--that which is called the "mass"--there is no greater mistake than to believe they are extraneous to history, mere inert instruments in the hands of the oligarchies that govern. States and institutions rest on this nameless mass, as a building rests upon its foundations. I mean to show you now by a typical case the possible importance of these little facts, so neglected in history. I shall speak to you neither of proconsuls nor of emperors, neither of great conquests nor of famous laws, but of wine-dealers and vine-tenders, of the fortuned and famous plant that from wooded mountain-slopes, mirrored in the Black Sea, began its slow, triumphal spread around the globe to its twentieth century bivouac, California. I shall show you how the branches and tendrils of the plant of Bacchus are entwined about the history and the destiny of Rome.
