Classical and medieval tradition holds that Archimedes used a system of polished bronze mirrors to focus sunlight on the Roman ships besieging Syracuse, setting them on fire. The story is first attested 350 years after the siege. Modern experimental reconstructions have produced ambiguous results.
Read the story →Marcus Claudius Marcellus took Syracuse in 212 BC after a two-year siege. He had ordered Archimedes spared. He arrived at the mathematician's house to find him dead by a Roman soldier's spear. Marcellus had the killer executed, gave Archimedes a state funeral, and is recorded as having wept publicly at the destruction of the captured city.
Read the story →Aristarchus of Samos proposed around 270 BC that the Earth orbits the Sun, not the other way around. The classical and late-antique Greek astronomical mainstream — including Hipparchus and Ptolemy — rejected the proposal on empirical grounds. The work survives only through a single passage in Archimedes.
Read the story →Chares of Lindos was the Rhodian sculptor who built the 33-metre bronze Colossus of Rhodes between approximately 292 and 280 BC. He had been a pupil of Lysippos. Late-antique tradition claims he killed himself when he discovered a substantial computational error in the statue's stress profile. The Colossus stood for 54 years and was knocked down by an earthquake in 226 BC.
Read the story →Serapis was a deliberately syncretic Greco-Egyptian deity created under Ptolemy I around 305 BC to unite the Ptolemaic kingdom's Greek and Egyptian populations under a shared imperial cult. The Serapis cult flourished across the Hellenistic and Roman Mediterranean for six centuries before the 391 AD Christian suppression substantially erased it.
Read the story →Eratosthenes's famous measurement of the Earth's circumference depended on a peculiar geographical fact about the southern Egyptian town of Syene. On the summer solstice, the Sun stood exactly at the zenith there — a single annual moment that defined the line we now call the Tropic of Cancer.
Read the story →An earthquake struck Rhodes in approximately 226 BC, knocking down the Colossus, damaging substantial portions of the city walls, and producing widespread Aegean damage. The Hellenistic kings of Egypt, Macedon, Syria, and Pergamon all sent substantial financial and material aid — the first known case of coordinated international disaster diplomacy.
