Robert Campin, now usually identified with the Master of Flémalle (earlier the Master of the Merode Triptych, before the discovery of three other similar panels), was the first great master of Flemish and Early Netherlandish painting. Campin's identity and the attribution of the paintings in both the "Campin" and "Master of Flémalle" groupings have been a matter of controversy for decades.
Campin was highly successful during his lifetime, and thus his activities are relatively well documented, but he did not sign or date his works, and none can be securely connected with him.
A corpus of work attached to the unidentified "Master of Flémalle", so named in the 19th century after three religious panels said to have come from a monastery in Flémalle.
