Josquin des Prez: A piece from the beginning of his career and a piece from towards the end of his career?

I am writing a paper on Josquin des Prez and I need to compare and contrast a piece of music from the beginning of his career to the end of his career and I can't find anything online. What are pieces from the beginning of his career and pieces towards the end of his career and can you tell me about them? Thanks to all who answer it would really help me!
