The work stems from an analysis of the opposite concepts of positivity and negativity. The rooster, both in Christian and Chinese symbolism, is closely linked to the struggle of good against evil and to the sun: it is the symbol of rebirth and is an ally of beneficial and protective forces; it carries out the function of surveillance by chasing away evil spirits, it embodies the masculine principle par excellence, virility. Allegorically, it represents the struggle of cosmic forces.

In the image we want to emphasize the opposition of good and evil, of the Yin-feminine principles, and the masculine Yang, night and day, moon and sun, hidden and manifest, shadow and light, passivity and movement, inertia and rest, energies destructive and life-giving forces, sickness and health, weakness and strength, negative and positive, empty and full, earth and sky, death and life, woman and man. The duality is emphasized not only in the contents through references to iconographic symbols of classical derivation but also by the formal choices, such as, for example, the cut of the frame, which decides to hide the female element.
