After exploring the kettle from so many angles and getting lost in so much information, it is time to make sense of this "kettle of fish" and conclude. This artifact has been used by ancient civilizations in order to heat and make the water suitable for drinking, such a basic necessity for human beings.
The word kettle evolved from the Old english cetel, to the Middle english chetel, which relates to the German Kessel. The same has probably happened with other like languages, as it can be deduced from the various ways to say kettle, for example the French and the Italian... Bouilloire and bollitore.
It has been so handy throughout history that myths have developed around it, turning it into a naughty magical creature that brings good fortune to whomever treats it well...

Maybe not at the time, but myths are timeless and something can be learned from them no matter the time in history in which they're analyzed.
It has been used to teach lessons from everyday life, as in the old English sayings, but also to highlight feelings in songs. To contrast or associate something so ordinary, normal and quotidian as a kettle boiling and whistling, with the turmoil of a troubled mind or to put children to sleep while learning about the use and parts of this old artifact which they are probably going to use someday.
