The website People of Color in European Art History showcases "works of art from European history that feature People of Color." The resource includes images of works of art from the pre-1000s to the 17th century.
From the website:
The focus of this blog is to showcase works of art from European history that feature People of Color. All too often, these works go unseen in museums, Art History classes, online galleries, and other venues because of retroactive whitewashing of Medieval Europe, Scandinavia, and Asia. Sometimes it’s just about really looking at artworks you’ve seen many times before, with a fresh perspective.
Although the focus is toward art dating from the fall of the Roman Empire until about 1650, it will also include Baroque and/or Early Modern pieces, as well as works from places other than Europe, Scandinavia and Asia. Ancient Greek, Egyptian and Celtic works featuring People of Color are also fair game.
