A tondo is a Renaissance term for a circular work of art, either a painting or a sculpture. The word derives from the Italian rotondo, "round". The term is usually not used in English for small round paintings, but only those over about 60 cm in diameter, thus excluding many round portrait miniatures – for sculpture the threshold is rather lower.

The Chartreuse de Champmol, formally the Chartreuse de la Sainte-Trinité de Champmol, was a Carthusian monastery on the outskirts of Dijon, which is now in France, but in the 15th century was the capital of the Duchy of Burgundy. The monastery was founded in 1383 by Duke Philip the Bold to provide a dynastic burial place for the Valois Dukes of Burgundy, and operated until it was dissolved in 1791, during the French Revolution.
