Answer to Question 1
Responses will vary depending on artwork selections. Renaissance artists in the north approached composition differently than Italian artists. Northern artists didn't share the scientific principles of composition, nor did they share a personal link to the creators of the Classical past. The Northern Renaissance style evolved out of the late Middle Ages and artists became increasingly absorbed with the countless details of the visible world. Northern Renaissance artists were more concerned with the look of their art; color, not form, was significantly important.
Answer to Question 2
The Renaissance brought immense changes to the world of art. These changes affected the way art looked, its perception, subject treatment, the societal position of the artists, identities and patron influences, and points of cultural references. In the Middle Ages painters were considered skilled craftsman, on a level with carpenters, goldsmiths, and other tradespeople. The Renaissance elevated the status of artists, from anonymous crafts workers to divinely talented individuals. The character of art patronage reflected this changing period. Before the Renaissance only the nobility and clergy functioned as patrons. By the 15th century a new class of patrons contributed, made up of very rich, socially ambitious merchant-rulers, fully able to afford extravagant expenditures on art, subsequently enhancing the economic situation of the artists.
