This history of citrus explores its cultivation from antiquity to the modern era. From mandarins and citrons to oranges and barberries, the book describes the significant journey of citrus as a global "superfood." Its path traces back to the trade routes of the Arabs, noble collectors of Central Europe, imperial conquerors, and merchants who risked their fortunes for the most prized fruit. This history weaves through the human journey, captured in literature and the art of cultures from antiquity to today. The encounter of Alexander the Great’s army with citron during the conquest of Persia, as well as the use of lemons and limes by the British naval forces during the Napoleonic Wars, highlights the importance of citrus in history. The book also includes information on the establishment of the Sicilian Mafia among citrus growers and how Renaissance arts and modern advertising, combined with visual representations, have contributed to the cultural wealth exuded by these remarkable fruits.
