The icon of the Feast shows the Archangel with a staff in his left hand, indicating his role as a messenger. Sometimes one wing is upraised, as if to show his swift descent from heaven. His right hand is stretched toward the holy Virgin as he delivers his message.

The Virgin is depicted either standing or sitting, usually holding yarn in her left hand. Sometimes she is shown holding a scroll. Her right hand may be raised to indicate her surprise at the message she is hearing. Her head is bowed, showing her consent and obedience. The descent of the Holy Spirit upon her is depicted by a ray of light issuing from a small sphere at the top of the icon, which symbolizes heaven. In a famous icon from Sinai, a white dove is shown in the ray of light.
