In Slavic folklore, the Firebird is a magical glowing bird from a faraway land, which is both a blessing and a bringer of doom to its captor.
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”.
A typical role of the Firebird in fairy tales is as an object of a difficult quest. The quest is usually initiated by finding a lost tail feather, at which point the hero sets out to find and capture the live bird, sometimes of his own accord, but usually on the bidding of a father or king. The Firebird is a marvel, highly coveted, but the hero, initially charmed by the wonder of the feather, eventually blames it for his troubles.
The Firebird tales follow the classical scheme of fairy tale, with the feather serving as a premonition of a hard journey, with magical helpers met on the way who help in travel and capture of the Bird, and returning from the faraway land with the prize. The most popular version is found in the tale of Ivan Tsarevich and the Grey Wolf.
