Looks fabulous. Just to clarify, those are later copies of the Visconti-Sforza cards.

An amazing book. The specific position of the planets in this diagram also dates the manuscript to 16 April, 816 (according to Elly Dekker and others)

The shelfmark is in the alt text. I don’t think it’s available online (the BL website hasn’t fully recovered as far as I know).

Yeah, not sure exactly what she’s doing but the marginal scenes often feature pets, hunting, mermaids, etc

They are very confusing! Can’t promise to change that, but I’m writing an article (due end of December) that’s in part about Isabella’s patronage. I’m arguing that she also commissioned our recently acquired cutting (MS M.1232).

Yes that’s why I said “to specialists on the topic.” Despite these earlier references, no one who works on this material has been aware of this leaf, which is surprising considering how important it is for understanding the scriptorium’s production ca. 1360.

What’s astonishing is the inscription linking it to Isabella of Guelders, the convent’s most important patron. She left 20 marks for the “splendid book” which I believe was completed after her death in 1354.

Chester and Jynx would like to attend.

Yes do it!

Thanks for putting this together
