right|thumb|343px|An illustration of the Caladrius' prophecies from the 1588 edition of the Physiologus. Copperplate by Pieter van der Borcht (I). The caladrius (or charadrius), according to Christian mythology in the Physiologus, 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.
