Devise a mystical narrative about a ghost artist who manifests his spirit in paintings, and each masterpiece is essentially a soul trapped onto canvas.
Leap into the ethereal space where art comes to life, but the artist remains unseen. What essence or part of their souls do these artists imbue in their paintings? Are these trapped souls willingly encapsulated or are they tricked? This prompt allows exploration of themes like the artist’s struggle, eternity, satiating artistic passion even in death, and the spiritual connection between an artist and their work. Dive into the supernatural through a prism of color and texture.
