There’s a point in a story I wrote recently where a retired king, discussing princehood with his adoptive son, mentions that if he officially becomes a prince, he gets a ceremonial knife, mostly as a joke; this is definitely the kind of knife I was thinking of when I wrote that (although the king and prince are Jewish and this is a Really Christian Knife).
It’s worth it to check out the Louvre’s record, click on the handle image, and then enlarge it; the carving is a masterwork and very fun to decipher.
[ID: Two images; one shows a knife with a steel blade and boxwood handle. The second image is a close-up of the handle, which has been carved with tiny intricate figures; it looks like the interior of a church with arched recesses, each of which has a tiny tableau of a biblical scene. It’s difficult to tell, but the scenes include top left, the Annunciation, lower left, Adam and Eve being expelled from Eden, top right, the crucifixion, and lower right, what is described in the record as the Lord’s Supper and the Kiss of Judas, though it’s tough to tell.]
