In 1901, sponge divers salvaged a corroded artifact from an ancient Roman shipwreck off the Greek island of Antikýthēra. The item has now been identified as an amazingly sophisticated, second-century-B.C.E. astronomical calculator.

Scientists who recently studied the “Antikythera Mechanism” using high-resolution X-ray tomography found that it was composed of at least 30 bronze gear wheels, originally housed in a wooden case. The device could accurately track the positions of the sun and the moon and predict lunar and solar eclipses. According to Nature magazine, the mechanism is “technically more complex than any known device for at least a millennium afterwards.”

By 1914, long-standing rivalries among European powers had stretched nerves taut and produced two opposing alliances: the Triple Alliance of Austria-Hungary, Italy, and Germany and the Triple Entente of Britain, France, and Russia. Moreover, those nations had political and economic ties with a number of other countries, including those in the Balkans.

At the time, the area called the Balkans was a politically volatile region chafing under the sovereignty of the bigger powers, and it was rife with secret societies scheming for independence. There, a small group of young people plotted to assassinate Austrian Archduke Francis Ferdinand during his visit to Sarajevo, capital of Bosnia, on June 28. A small police presence made their task easier. The would-be assassins, however, had minimal training. One youth threw a small bomb but missed his target, and others failed to act when the time came. Gavrilo Princip was the one conspirator who succeeded—and only by sheer accident. How so?

When Princip saw the archduke drive by still unharmed by the bomb, he tried to get to the car but in vain. Dispirited, he walked across the road to a café. Meanwhile, the archduke, angry about the attempted bombing, decided to change his route. However, his driver, unaware of the change in plans, set off in the wrong direction and had to turn the car around. At that very moment, Princip came out of the café and was literally presented with a sitting target—the archduke in his open car less than ten feet [3 m] away. Princip approached the car and fired two shots, killing the archduke and his wife. A naive Serb nationalist, Princip likely had no idea of the avalanche he had just triggered. Yet, he could not take sole blame for the horrors to come.
