As I look at the bones, sometimes they seem to contain the spirit of the animal. Sometimes this is in their actual physicality; the cattle bones are sturdy, chunky and robust, whereas the bones of a deer are smooth, elegant and fine. Sometimes it's in the type of bone and what it’s used for, such as in the talon of an eagle, its sharp, assertive point embodying the fierceness of the creature itself.
This really chimes with the idea of saints’ relics. Medieval Christians believed the bones of a Saint had the same powers of the Saint and just by touching the bone that power could be felt. We can think about these animal bones in the same way, containing the lasting spirit of the animal that is now long gone.
I find myself staring at the eagle talons on my desk with a quiet reverence.
