1470–1531) was a French illuminator and painter, whose works are difficult to attribute since none of them was signed or dated.
His middle period, characterised by tight compositions and sharply defined colouring, is typified by his Roman de la Rose, the Nouailher Missal and the Book of Hours, probably painted for Charles, Count of Angoulême about 1480.
Surprisingly, 17 engravings by Israhel van Meckenem were included in the tome and coloured by Testard.
He produced another Book of Hours, a copy of Dioskurides and mythological illustrations after Solinus and Pliny titled Les Secrets de l'histoire naturelle contenant les merveilles et choses memorables du monde.
He also illustrated Matthaeus Platearius' "The Book of Simple Medicines" [1]
