Promethean is an adjective that means boldly defiant or creative.
Getting its origin from the Greek God Prometheus known for his daring inventiveness and creativity, our word of the day is often used to describe scientists and inventors who have created something astonishingly new. For example, keep in mind that the novel Frankenstein was first subtitled ‘The Modern Prometheus’ in reference to the mad scientist to brought the dangerous monster to life.
Many of the important figures of contemporary science have a promethean quality about them. It often takes a bold temperament to create something that truly shakes up the world.
