In Slavic folklore, the Firebird (Russian: Жар-пти́ца, Zhar-ptitsa; Ukrainian: Жар-пти́ця, Zhar-ptytsia; Serbian: Жар-птица or Žar-ptica; Croatian: Žar ptica; Bulgarian: Жар-птица, Zhar-ptitsa; Macedonian: Жар-птица, Žar-ptica; Polish: Żar-ptak; Czech: Pták Ohnivák; Slovak: Vták Ohnivák; Slovene: Rajska/zlata-ptica) is a magical glowing bird from a faraway land, which is both a blessing and a bringer of doom to its captor. Some believe it can see the future.
The Firebird is described as a large bird with majestic plumage that glows brightly emitting red, orange, and yellow light, like a bonfire that is just past the turbulent flame. The feathers do not cease glowing if removed, and one feather can light a large room if not concealed. In later iconography, the form of the Firebird is usually that of a smallish fire-colored peacock, complete with a crest on its head and tail feathers with glowing "eyes". It is beautiful but dangerous showing no sign of friendliness.
The story of the Firebird inspired many literary works, including "The Little Humpback Horse" by Pyotr Yershov. The most famous production of the Firebird was by Sergei Diaghilev of Ballets Russes who commissioned composer Igor Stravinsky to create the enormously popular large-scale ballet score known as The Firebird.
