Gamayun is a prophetic bird of Russian folklore. It is a symbol of wisdom and knowledge and lives on an island in the east, close to paradise. This legendary creature has the body of a bird and the head of a beautiful woman, being quite similar to the Phoenix and being immortal. The Russian folklore compares it to the three prophetic birds, joining Alkonost and Sirin.
This painting (oil on wood) from the last third of the 17th century alludes to the popular proverb "Nimm dich selbst bei der Nase" ("take yourself by your nose"). It's also called "Vogel Selbsterkenntnis" (Bird of self-knowledge) and exists in several samples (three, at least, in that same museum).
