To what extent were works of art from the Renaissance period

Product of cultural contact between European locations? Drawing from examples from three different chapters in bk. 2 explore the Renaissance as a product of artistic exchange between European centres. End of question.
Please make sure to answer the question with references to the locations.
Last time I had to rework quite a bit on the finished work. I am sending by email, a copy of the book and more instructions. And of course the examples and chapters chosen. Thanks I think I should be having somebody knowledgeable in Renaissance art to write this any ways, that’s why I do this, I am too pressed for time. If I have to rewrite the whole thing, it defeats the purpose and a waste of money I do not have. Thanks for your understanding and support.
Here enclosed is the ebook needed for the assignment. And my three chapters and examples are,
Chapter 3 : plate 3.3 the tapestries in Brussels and the participation of different artists ex Raphael.
Chapter 4 : plate 4.12. Sienna, the collaboration of artists from else where
Chapter 6: plate 6.14 Venice, Mehmet ll, Turkish and Bellini.
Another sheet of tutor recommendations follows another email.
Thanks let me know if you received everything okay.
