Some of the artists were influenced by Duccio alone to the point of creating a decided affinity or kinship between their works and his. Among them was the Master of Badia a Isola, and Ugolino di Nerio, along with Segna di Bonaventura and their sons. Other artists were influenced also by other schools, and these include the Aringhieri Master (think of the massive volumes of Giotto), and the Master of the Gondi Maestà (who shows the influence also of Simone Martini).
