Quintus Curtius Rufus was a 1st-century AD Roman historian, rhetorician, and author active during the reign of Emperor Claudius (41-54 AD). He is best known for his work 'Historiae Alexandri Magni' (History of Alexander the Great), one of the most complete extant Latin biographies of Alexander. Little is known about his life; he may have been a Roman equestrian or official. His writing combines historical narrative with rhetorical embellishment, reflecting Roman imperial values. The work survives in ten books, with the first two lost. It remains a key source for studying Alexander's campaigns and Roman historiography.
