I just saw that beautiful mourning ring made with an actual eyeball and dated from early 19th. Does anyone know something about that practice ? Any references or other exemples ?
This may or may not be relevant to you, but I just heard about an eye set in silver as a relic of a Jesuit priest (Oldcorne), on a radio program (see link for transcript). It reminded me about this and thought it might be of interest to you. Obviously it is earlier than your ring, but they may have common origins?
I suppose you may have found this specimen online (here https://www.instagram.com/p/BsWRlt3lEGb/ perhaps)? Lindsey Fitzharris seems to know more about this. https://www.drlindseyfitzharris.com/
