Two Breton illuminators amended and expanded the imagery.
In 1442, an artist working in Nantes for Francis I of Brittany painted the portrait of Isabella Stuart over that of the original owner on fol. 20r. The image was adapted in two stages. Around the same time Isabella’s arms were added to the borders on fol. 20r and throughout the volume. Another Breton illuminator painted a new miniature including the image of Margaret of Brittany for the prayer added c. 1455 on fol. 28r.
