Medieval uses of wheelbarrows?

If anyone knows the origin of this illustration, please let me know. I found it at the French Wikipedia page, but I think it's from a book, as words seem to show through. Petites questions et grands problèmes: la brouette, on the history of the wheelbarrow, perhaps, by Bertrand Gille. I don't know whether he did his own illustrations (nor whether it is from that book). If so, the illustrations are from the 1980 or slightly earlier, perhaps.
