Gianfrancesco Penni
Born in Florence to a family of weavers, Penni entered Raphael's workshop very early in his life, and collaborated with him on several works, including the famous Rooms of the Vatican Palace, as well as the frescoes of Villa Farnesina, both in Rome. Heinrich Wölfflin and some other writers credited him with the entire execution of the Raphael Cartoons, with Raphael only creating the initial design, though more recent writers believe Raphael did much of the work himself.
Juan Correa de Vivar
Juan was heavily influenced by Raphael. One of his most important works was the altarpiece of the church of Almonacid de Zorita, in the province of Guadalajara. This work was done in collaboration with Alonso de Covarrubias. It was destroyed in Spanish Civil War in 1936-39. 
From Raphael he took his colorful tone and delicate and smooth figures. Over the years his style evolved into more dynamic forms of Mannerism, especially with respect to the way to bring about violent movement in the figures.
