The hook of the cooking vessel preaches diligence and domestic cosiness.
The hook of the cooking vessel has always been in the centre of the housekeeping in the old days
According to the old Indo-Germen use, the grom would lead his bride around the hook of the cooking vessel 3 times, before the bride would start using the new house/farm.
Later, when it was custom to have the fireplace in the wall, it was only the cooking vessel that was used for this "ceremony".
In the old days there would be a fireplace in the middle of the big open room of the farm
When the cooking vessel itself hangs on the hook, it symbolises hospitality.
There would always be some food in the cooking vessel to feed a hungry visitor. This was also the symbol of a good housewife.
