Can you tell me more about it?
As you may have read in the label, portraits of the Inca kings were important things to own and display for indigenous people of Peru. A version like this would have been easier to hide during the outlawing of displaying Inca portraits.
The text, in Spanish, describes the Inca empire. The style of the paintings is European-inspired. They can be compared to religious paintings of Biblical figures. The artist who painted these likely also painted for churches in Peru.
