The digital image of Discussing the Divine Comedy with Dante (o/c, 2006) by Chinese artists Dai Dudu, Li Tiezi, and Zhang An, comes with more than dozens of “influential people” from world history. It is also interactive, as the figures (and some of the objects and creatures) have all been tagged — roll the cursor over each image and most will show you a label identifying the person, which in turn is a link to a corresponding Wikipedia page. This is a large image, so remember to scroll to the right for the remaining figures.
Don’t have time for all the links? Here’s a list of many figures in the painting. h/t Christine Hilker
