St. Christopher's purse
I was staring at a photo of a statue not too long ago when I suddenly recognized I was looking at a small accessory I hadn't expected to see. It's a "disk" rosary -- one of the much less common types that uses a string of flat disks as prayer counters, rather than round beads.
This is a wooden statue from about 1520, depicting St. Christopher carrying the Christ Child. It's currently in Cologne, in the cathedral treasury.
In the close-up photo, take a look at what's hanging from St. Christopher's belt on his right side (the viewer's left), on top of his purse. It's a loop of about ten round, flat disks with holes in the middle on some sort of central string. The disks look as though they might be somewhere between 1/2 inch and an inch in diameter. Since this is a statue, of course, they are displayed nice and flat where we can see them clearly, rather than as jumbled as they would probably be if St. Christopher himself were posing for the photo
I think this is a disk rosary, because I'm comparing it with this one, one of the relatively rare surviving examples:
I'm delighted to have found this, because it's only about the third or fourth historical instance I've seen of a rosary of this type.
