Why was Sandro Botticelli’s painting Fortitude important to his career?

Sandro Botticelli’s painting Fortitude (1470) was a pivotal milestone in his career because it marked his establishment as an independent master with his own workshop in Florence.1

Commissioned for the Tribunale dell’Arte della Mercanzia (the merchants’ tribunal), the work served as his first dated painting. Its creation was secured by Tommaso Soderini, a prominent Medicean partisan, highlighting the early importance of influential political patronage in Botticelli's professional rise.12

Stylistically, Fortitude demonstrated a significant evolution in Botticelli’s artistic development. While he had previously trained under Filippo Lippi, Fortitude showcased his transition away from Lippi’s softer, frailer figural style. Influenced by the sculptural work of Antonio Pollaiuolo and Andrea del Verrocchio, the painting displayed a new, robust naturalism and sculptural strength. It also introduced his characteristic use of ocher in flesh tones, which provided a distinct brown warmth that contrasted with the pallor typical of his teacher’s work.1
