A portrait of the Priestess of Delphi (Pythia) from Greek and Roman mythology, seated on a completely backless chair with her back straight and poised. She is draped in a sacred, divine fabric that flows elegantly, with a soft, slightly transparent veil wrapped around her head, partially concealing her hair. The background is a deep, pure black, untouched by light. The figure is illuminated by soft, divine light from behind, casting a gentle glow over her back, while her face is turned slightly toward the viewer, her gaze directed downward. Subtle shadows fall across her face, adding depth and mystery. The scene exudes a sense of sacredness and quiet power, with a touch of artistic flair. Her posture radiates strength and grace as she sits tall on the backless chair, embodying wisdom and divine presence. --ar 9:16
