Remember that a little learning can be a pleasant thing. Italy gives much, in beauty, gaiety, diversity of arts and landscapes, good humor and energy—willingly, without having to be coaxed or courted. Paradoxically, she requires (as do other countries, probably more so) and deserves some preparation as background to enhance her pleasures. It is almost impossible to read a total history of Italy; there was no united country until a hundred years ago, no single line of power, no concerted developments. It is useful, however, to know something about what made Siena run and stop, to become acquainted with the Estes and the Gonzagas, the Medicis and the Borgias, the names that were the local history. It helps to know something about the conflicts of the medieval church with the Holy Roman Empire, of the French, Spanish and early German kings who marked out large chunks of Italy for themselves or were invited to invade by a nervous Italian power. Above all, it helps to turn the pages of a few art and architecture books to become reacquainted with names other those of the luminous giants.The informed visitors will not allow himself to be cowed by the deluge of art. See what interests or attracts you; there is no Italian Secret Service that reports on whether you have seen everything. If you try to see it all except as a possible professional task, you may come to resist it all. Relax, know what you like and don’t like—not the worst of measures—and let the rest go.
