 Often the "bas-de-page" and main miniature are by different artists, as in the Getty's leaf, and also the borders and historiated initials.Hand G, who may or may not have been Jan van Eyck, paralleled the achievement and innovation of that artist's panel paintings in the miniature form, firstly in the technical development of the tempera medium and use of glazes to achieve unprecedented detail and subtlety, and also in his illusionist realism, especially seen in interiors and landscapes – the John the Baptist page shows both well.Many of the background portions of the attributed leaves seem concerned with the depiction of receding space, and it is often thought that in this aspect that the work of Hand G is most innovative.
