    As a result of his famous "double pincer" maneuver, 70,000 Roman soldiers died within the space of a few hours on a field the size of New York's Central Park. Yet, as devastating and startling as Cannae was, it was only one of a long list of incredible achievements. Hannibal's fantastic 1,000-mile march across the Alps from Spain to Italy was one of the wonders of ancient times. He began his hazardous journey with 90,000 infantry, 12,000 cavalry, and 37 elephants. By the time he reached the Valley of the Po, more than 30,000 troops and many of his elephants had perished, but he still managed to stay in Italy for sixteen years.Blending biography and military adventure, Hannibal is a portrait of a military genius who was also a highly civilized man. The son of Hamilcar Barca, a famous general in his own right, Hannibal was a student of the Greek classics. But his father's lifelong grudge against Rome fostered in the son a deep hatred for that Republic and a fierce determination to subdue it forever. This resulted in the bloody battles of Lake Trasimene, Campania, Nole, Capua, and Zama, all of which Leonard Cottrell describes with vigor and authority. In gathering material for Hannibal, Cottrell traveled the entire route that Hannibal took across the Alps, thus bringing to his account a valuable firsthand knowledge of his subject. With the drama and authenticity for which he is famous, Leonard Cottrell describes Hannibal's amazing campaign-a saga of victory after victory which fell just short of its ultimate goal: the annihilation of Rome.

    Yet the privilege and decadence often associated with the Roman elite was underpinned by the toils and tribulations of the common citizens. Here, the eminent historian Robert Knapp brings those invisible inhabitants of Rome and its vast empire to light.He seeks out the ordinary folk laboring men, housewives, prostitutes, freedmen, slaves, soldiers, and gladiators who formed the backbone of the ancient Roman world, and the outlaws and pirates who lay beyond it. He finds their traces in the nooks and crannies of the histories, treatises, plays, and poetry created by the elite. Everyday people come alive through original sources as varied as graffiti, incantations, magical texts, proverbs, fables, astrological writings, and even the New Testament.Knapp offers a glimpse into a world far removed from our own, but one that resonates through history. "Invisible Romans" allows us to see how Romans sought on a daily basis to survive and thrive under the afflictions of disease, war, and violence, and to control their fates before powers that variously oppressed and ignored them.

    A mysterious lodestone whose powers affected metal was known to the Chinese emperor. When this piece of metal was suspended in water, it always pointed north. This unexplainable occurrence led to the stone's use in feng shui, the Chinese art of finding the right location. However, it was the Italians, more than a thousand years later, who discovered the ultimate destiny of the lodestone and unleashed its formidable powers. In Amalfi sometime in the twelfth century, the compass was born, crowning the Italians as the new rulers of the seas and heralding the onset of the modern world. Retracing the roots of the compass and sharing the fascinating story of navigation through the ages, The Riddle of the Compass is Aczel at his most entertaining and insightful.
