A flare, a pyrotechnic device that emits intense light or heat without exploding, functions as a tool for signaling, illumination, and defense in both civilian and military settings. Authors have examined its symbolic and practical roles: Bern Keating emphasizes its tactical use in warfare, while Stephen Graham evokes its visceral, almost chaotic radiance.
F.W. Farrar uses dramatic imagery of flashes and bursts, and Mary Heaton Vorse employs metaphors to illustrate its ability to spark conflict. These diverse portrayals highlight the flare’s dual nature as both a practical tool and a powerful symbol of human struggle and communication.
