During the Renaissance, one had to become an apprentice under a master
in order to learn varying artistic process and thus finely tune their
own techniques as an artist. Based on these teachings, it can be
observed that artists adapted their style around their master's.
Starting in the early Renaissance, similarities were seen in Giotto's
style after working under his master Cimabue. Leonardo da Vinci and his
master Verrocchio also shared similar characteristics in the High
Renaissance. Throughout the Italian Renaissance, the influence that a
master artist had on this apprentice was seen through the work of
Raphael and his masters. This relationship is shown through the use of
similar techniques along with rendering, stylistic choices and
contextual choices. These techniques show the importance of teaching to
an artist early in their artistic careers.
