Gaddi's technical approach relied on a direct study of human emotion. He moved beyond the static figures of his predecessors to capture individual facial expressions, such as the suspicion of a gambler or the grief of a mourner. His work in the refectory of Santa Croce shows a mastery of large-scale narrative, where he balanced complex crowds with clear architectural lines. He used colour to define form rather than merely as decoration, a method that gave his figures a sense of weight and presence.

Gaddi’s work provides a window into the transition between the Gothic style and the early Renaissance. His prints offer a sense of narrative structure that works well in domestic spaces. The focus on individual psychology ensures that these religious scenes remain relatable. His ability to render light and shadow creates a spatial depth that complements contemporary interior design while maintaining a connection to classical Florentine history.
