Caladrius

The caladrius, according to Roman mythology, is a snow-white bird that lives in the king's house. It is said to be able to take the sickness into itself and then fly away, dispersing the sickness and healing both itself and the sick person. The caladrius legend formed part of medieval bestiary materials, which typically provided a Christian moralization for the animals they discussed.

Origin
It has been theorized that the caladrius is based on a real bird. Due to descriptions of it being completely white with no black on it, it is possible that it was based on the dove, or possibly some sort of water bird such as the heron. The art historian Louis Réau believed it was most likely a white plover.

In medieval bestiaries
Medieval interpretations focused on the diagnostic potential of the bird: if it looks into the face of a sick person, the person will live; if it looks away, the person will die. This is compatible with the idea that the caladrius' look draws the sickness into itself; the bird is then said to fly up to the sun, where the disease is burned up and destroyed. In the Christian moralization, the caladrius represents Christ, who is pure white without a trace of the blackness of sin. The bird shows how Christ turns away from unrepentant sinners and casts them off; but those to whom he turns his face, he makes whole again. Sometimes this moral is used specifically against the Jews to describe how, because the Jews did not believe, Christ turned his face from them and toward the Gentiles, taking away and carrying their sins to the cross.

In popular culture
In the Saturday Night Live sketch, "Theodoric of York, Medieval Barber", the title character (played by Steve Martin), uses a caladrius (portrayed by a live bird, most likely some form of dove or pigeon) in an attempt to diagnose a patient. The difficulties of using live animals on live television provided most of the humor for the few seconds of the bird's appearance.

In the video game Age of Mythology: The Titans, a myth unit available to the Atlanteans is the Caladria, which serves as a flying scout and healer, though it more closely resembled an angel than a bird.

A song dedicated to the Caladrius ("Pasărea Calandrinon") appears on the album "Cantafabule", released in 1975 by Romanian rock group Transsylvania Phoenix.
