The absence of any single work that he can clearly be said to have completed continues to make an assessment of his achievement highly uncertain, although for centuries he had the reputation of being an outstanding founding artist of Early Netherlandish painting.

[1] The division of surviving works between Hubert, early Jan van Eyck, and other painters has been the subject of great debate among art historians, involving the Ghent Altarpiece, the many different hands that can be detected in the Turin-Milan Hours, and other pieces.
After a period in the mid-20th century when there was a strong tendency to attribute work away from Hubert, he has made something of a comeback in recent decades, but there is still a wide range of opinion among specialists.
He is likely to have begun The Three Marys at the Tomb now in the Museum Boijmans Van Beuningen in Rotterdam, but this seems to have been finished by another artist some decades later and has suffered from the restoration.
