It seemed a crying shame to throw away the leftover scallop shells from our NYE supper, so we pondered what we could do with them. Quickly we both decided that they could feature in a hanging wind chime thingy for the garden and I quickly volunteered my modest stash of holey stones to accompany them. Mr GBT, being a making/repairing wizard, strung them up on some brass wire, but I still didn't feel it was quite finished somehow. Overnight the missing detail came to me and by the morning I added in the red ribbon [salvaged from Christmas crackers]. When I stood back from it I had to smile....every part of it also has an apotropaic element!
The scallop shell features heavily in Christianity and is the symbol of St James [it's littered along the route of the Camino de Santiago] who is the patron saint of pilgrims. If you see it on a tomb, then it signifies that the person has been on at least one pilgrimage. This example is Richard Cheltenham's and can be seen in Tewkesbury Abbey.
In pre-Christian times it was used as a symbol of the setting sun. Together with the red which was used to deflect evil spirits/witches and those with malicious intent and the hagstones [more detail here http://gnatbottomedtowers.blogspot.com/search?q=hag+stones it seems like we all have bases covered should someone or something nefarious try and cross the threshold. I love it when the universe has other plans.......
