Ladies with Rings

[Koen G]

Hi Marco, I thought so too (I generally lean towards mirrors for the overly large rings as well), but then I saw that the inside of the circle was painted gold, while mirrors are usually blank or blue. Usually the object held by the whore of Babylon refers to the Bible verse "decked with gold and precious stones and pearls, having a golden cup in her hand full of abominations and filthiness of her fornication". 

I guess there is a connection between the "gold and precious stones" and the mirror, in that she cares more about appearances and earthly goods than spiritual salvation (vanitas).
