Il martirio di Santa Caterina by castrato singer, composer and writer Pier Francesco Tosi is a fine example of the rich tradition of late-Baroque oratorio. It is the embodiment of Tosi's famous treatise on a vocal style that emphasised expressive authenticity over virtuoso display. This story of the martyrdom of Catherine of Alexandria for refusing to convert to paganism is filled with deeply poignant music that depicts her prodigious inner strength, representing the power of faith through grief, courage, compassion, and admiration for the fortitude of others
