What does the "e" refer to?

Looking at leaves and cuttings recently at the V&A Museum I looked again at one I had not seen in person for more than a decade:

Full-Page Crucifixion from a Missal(?) dated 1480

UPDATE, 5 Sept 2016
I now have some slightly better, and significantly larger, images (click each image to see the large versions):

     
It no longer looks as if John has a large halo, but it is clear the Christ does have one.
The Cross is 'T'-shaped.
Mary is wearing a veil and has her hand to her cheek.
John appears to have his hands clasped in front of his chest.
A skull is clearly visible at the foot of the Cross.
There is a coiling acanthus border around the image.

The blurry images above are variants of my only visual evidence for the appearance of a large full-page miniature from the same Christie's sale as in a previous post.

It appears that Mary has her left hand to her cheek, and it looks as though John has an unusually large halo, or perhaps there is a figure standing behind him wearing a pale cloak.

Here is the Christie's description:

Even though the image is not at all clear, the presence of the date "1480" and letters "J.K." should make a definitive identification possible. If anyone has a better image, or knows where this leaf is now, please let me know.

Unidentified Heraldry, Perhaps of a Patron Named Anthony or a Knight of the Order of Saint Anthony?

Beth Morrison at the Getty Museum hopes that someone can identify the heraldry that appears several times in the borders of their manuscript of the Invention et translation du corps de Saint Antoine:
