A few days ago, Morning Coffee dispenser Dan Weiss mentioned Medieval POC, a blog examining the appearance of people of color in European art history.

The blog’s creator, Malisha Dewalt, recently participated in a roundtable chat with other art historians and medievalists for NPR’s Code Switch.

Their conversation is eye-opening, ranging from the way art textbooks crop paintings to exclude images of black people to common portrayals of Biblical figures as black.
