Round and round...

If you had a fireworks party last night, did you have any Catherine wheels?  And if so, did you wonder why they are called Catherine wheels?  Well they are named after Saint Catherine of Alexandria, who was an early Christian martyr who was condemned to death by being "broken on the wheel" which involved being strapped to a wagon wheel and then having all your bones broken by beating.  The story goes that before the beating could start, the wheel miraculously broke apart.  Didn't do poor Catherine much good, mind you, as she was subsequently beheaded.
