Saint Barbara is a 1437 brush stroke drawing on chalk ground laid on an oak panel, signed and dated 1437 by the Netherlandish artist Jan van Eyck. Some areas and passages are more detailed than others, and it has long been debated if the panel was left as van Eyck intended or if it is an unfinished painting. If it was intended as extant, it would be the earliest surviving drawing of any artist, although not prepared on paper or parchment. Evidence to support this includes that the work was highly regarded at the time by Flemish aestheticists as an object in itself.
