Batillum or vatillum was an ancient Roman iron shovel with a short handle used for various purposes, especially as a fire-shovel, chafing-dish, and for burning incense.
The name is possibly related to battualia "the exercise of soldiers and gladiators in fighting and fencing" which is related to the English verb to beat or to vas a vessel (in some Latinate languages 'b' and 'v' can be interchangeable).
