Master of the San Niccolò Altarpiece

The Master of the San Niccolò Altarpiece is an anonymous Italian painter active in Tuscany during the late 14th to early 15th century, identified primarily through a key altarpiece associated with the church of San Niccolò. Working within the tradition of late Gothic painting, this artist produced devotional panels characterized by gold leaf backgrounds, elongated figures, and expressive religious iconography. The master's works have appeared at major auction houses including Christie's and Sotheby's, attributed through stylistic analysis rather than documentary evidence.
