Nike is the personification of victory, in battle, in athletic contest, and in any struggle that can be won. In Hesiod's Theogony she is a daughter of the Titan Pallas and the river Styx, and with her siblings Kratos (Strength), Bia (Force) and Zelos (Rivalry) she took the side of Zeus in the war against the Titans, standing beside him ever after. This origin makes her less a goddess with her own myths than an attribute of the powers she serves: winged and swift, she appears again and again in art alighting to crown a victor or held in the hand of a greater deity. A small Nike often stands in the palm of Zeus or of Athena, signifying that victory is in their gift. Rome honoured the same figure as Victoria, and the winged victory remained one of the most enduring images to pass from antiquity into later European art.
Athens took a distinctive, superstitious approach to the goddess on its own Acropolis: the small Ionic Temple of Athena Nike, completed in the 420s BCE, is said by ancient sources to have housed a cult statue of Nike deliberately made without wings, so that Victory, once installed on the Acropolis, could never fly away and abandon the city, a belief later writers such as Harpocration record. The most famous surviving image of the goddess, the Nike of Samothrace, a headless, armless marble masterpiece of the Hellenistic period discovered on the island of Samothrace in 1863 and now displayed at the top of a grand staircase in the Louvre, shows her alighting on a ship's prow, wings still fully spread, and remains one of the most reproduced sculptures from the ancient world.
