The Book of Promise(s) is the book pictured with the lion http:// tinyurl.com/3b2zh9 on which is written: "Pax tibi, Marce, evangelista meus. Hic requiescet corpus tuum," (Peace unto thee Mark my evangelist. Here your body will rest.) It is the book of the promise made by the angel to St. Mark, seen here in a Blundellian vision.
