I wish I could see examples of art from around the world at the same time period. I'd love to do a comparison of pottery styles and techniques in China and the Americas. There's often surprising commonalities, though the civilizations grew separately. Further, I'd also love to see connections and influences between regions. How did Koran manuscripts influence those of the Bible, and vice versa? How did Chinese ceramic motifs influence those in Persian ceramics? What are the flows of currency in the ancient world?
