Cavaradossi is often described as a romantic tenor, but psychologically he is far more complex: an intellectual, a political dissident, an artist and a man whose emotional stability stands in sharp contrast to Tosca's volatility. His tragedy is that of a man too principled for a corrupt world, a poet crushed by a regime incapable of understanding the values he embodies.
