Andrea di Bartolo, an eminent Italian painter of the Sienese school, was born between 1358 and 1364 in Siena, where he also passed away in 1428. The son of the renowned painter Bartolo di Fredi, Andrea's artistic journey began under his father's tutelage, collaborating on significant projects such as the Calzolari chapel and the chapel of San Giacomo, the latter of which he frescoed in 1405. His work reflects a blend of influences, including his father's stylistic elements, the dynamic compositions of Spinello Aretino, and the refined elegance reminiscent of Simone Martini. Andrea di Bartolo is celebrated as a pivotal figure in Sienese painting, bridging the late 14th and early 15th centuries with his distinctive contributions. Among his notable works are the 'Massacre of the Innocents,' a collaboration with his father, and the 'Resurrection,' both housed in the Walters Art Museum in Baltimore. His oeuvre includes a variety of religious themes, executed with tempera and gold on panel, showcasing his mastery of the medium and his innovative approach to traditional subjects. Pieces such as the 'Triptych of the Crucifixion' and the 'Coronation of the Virgin' highlight his skill in narrative composition and his ability to convey spiritual grandeur. Andrea di Bartolo's legacy is preserved in prestigious collections worldwide, from the Pinacoteca Nazionale in Siena to the Museo Thyssen-Bornemisza in Madrid, attesting to his enduring influence on the art of his time.
