This is a perfect mix of art history and technology. This is what online galleries need to do.
Also, I'm personally blown away by the details in this painting. We zoom into the details and everything is perfectly shaded or positioned, and has significance. When you zoom into the details, you see the mermaid and the mer-knight in the middle of the water. There are the birds in different sizes and performing different activities. Who..How.. Why? I can imagine this becoming full time mission for historians to dissect these components, all the while enjoying the beauty of the painting.
Yes, I'm obsessed.
