 In spite of the obvious participation of assistants, the entire cycle seems to have been planned by a single artist and can be considered as homogeneous and characteristic of his style.The cycle was largely based on the later works of Giunta Pisano but also shows the influence of such Umbrian artists as Rainaldetto di Ranuccio, Simeone and Machilone and of contemporary manuscript illumination, for example the Gospel Book of Giovanni da Gaibena (Padua, Bib.Capitolare).
