What aspect of Caravaggio's work was considered a valid alternative to classicism, according to Giovanni Bellori?

Giovanni Bellori viewed Caravaggio's work as a valid alternative to classicism primarily due to its embrace of irrationality. In the context of the late Renaissance and Baroque periods, classicism emphasized idealized forms, harmony, and rational proportions, drawing inspiration from the ancient Greco-Roman tradition. However, Caravaggio diverged from this tradition by focusing on naturalism, emotional intensity, and the dramatic use of light and shadow (chiaroscuro).

This irrationality in Caravaggio's compositions arose from his departure from the traditional rules of perspective and proportion, instead capturing raw human emotions and experiences infused with a sense of immediacy and realism. Bellori appreciated this shift because it reflected the complexities of real life, engaging viewers on a more personal level than the serene and ordered presentations of classicism. Hence, Caravaggio's approach not only challenged classical ideals but also enriched the narrative and emotional range of painting during his time.
