Ewa Podleś likewise stated that "It's enough to hear her, I'm positive! Because she could say everything only with her voice! I can imagine everything, I can see everything in front of my eye." Opera director Sandro Sequi, who witnessed many Callas performances close-up, states, "For me, she was extremely stylized and classic, yet at the same time, human—but humanity on a higher plane of existence, almost sublime. Realism was foreign to her, and that is why she was the greatest of opera singers. After all, opera is the least realistic of theater forms... She was wasted in verismo roles, even "Tosca", no matter how brilliantly she could act such roles." Scott adds, "Early nineteenth-century opera... is not merely the antithesis of reality, it also requires highly stylized acting. Callas had the perfect face for it. Her big features matched its grandiloquence and spoke volumes from a distance."
