A stone?  A wheel?  No, Faludy goes one better, and I was lucky to find a roll-able coin stamped with the head of a king who lost his.

… and in the evening the sun rolls down below the horizon like the severed head of a king.

Speaking of ‘rolling’ and ‘kings’, see this superb piece of advice by Lear’s fool.

And keep your head.
