The avian humanoids always seemed like fantastical creatures that mediate between heaven and earth by having human and avian features together. They mostly referred to the souls lingering between the living and the divine. There are many types of them, and this paper is specifically concerned about the human-headed bird imagery; and how it is depicted in different ways and what are their symbolic meanings in many cultures. This specific imagery appeared in many different mythologies along history; such as the ‘Ba’ in the Ancient Egyptian, ‘Sirens’ and ‘Harpies’ in the Greek and the Byzantium, the ‘Humayun’ in the Mesopotamian and perhaps in the Islamic too; and eventually, the ‘Alkonost’, the ‘Sirin’, and the ‘Gamayun’ in the Slavic mythology. An analytical comparative study of this imagery in different mythologies and in the paintings by different artists, such as P. Rubens, J. Pasch, V. Vasnetsov, and M. Vrubel; will be followed.
