 While Jacobello's earliest surviving and confirmed work is dated in 1407, he is thought to be the painter of a "Crucifixion" piece in the Matthiesen Collection and the "Virgin and Child" of Piazzo Giovaneli, both painted in the late 14th century.The Crucifix was a common theme in Jacobello's earliest works, though as a subject it was a fairly common focus of many painters at the time.Art historian Andrea de Marchi was the first to suggest that a single author was responsible for these 'neo-giottoesque' paintings inspired by mainland painters Altichiero and Jacopo Avanzi and coined the author's unknown name as "Master of the Giovaneli Madonna".
