This is my "curfew". It is thought that the word originated with the Normans (covrefeu - cover fire). A bell was rung at a certain time of night as an order to cover or extinguish fires and take to bed. It is also the name of the item on the right used to cover the hearth over night.
The item on the left is a little tinder box. Heaven forbid if your fire went out, either through a soot fall or the arrival of the chimney sweep but it was necessary to get the fire going again as quickly as possible so a tinder box was a vital piece of equipment in any 17th century home. It contained a piece of moss, a stone and a flint.
It wasn't unheard of for renovations or demolitions of these old buildings to reveal skeletons of children stuck in chimneys. Sometimes the chimney sweep didn't wait for the actual fire to go out before sending the "boy" up. Illegitimacy and the death rate was so high that replacing him with one of the many orphans running around was never an issue!
