A favourite and incredibly important book in my collection is 'Form Emphasis for Metalsmiths' by the late silversmith Heikki Seppa.
I can only dream of one day being (when I'm really old probably) as technically competent as he was, and in the meantime have experimented with my own take on his tutorial of techniques.
The most frequently looked at pages in his book are right at the back in his pictorial glossary. Here, Seppa has detailed (with lovely little hand drawn doodles) some worldly forms and their nomenclature.
Here are some of them:
I find his connection between the forms and the derivatives of language fascinating. It's just a lovely complete circle of visual form, historical symbolism and language development.
Thanks Heikki, and you should all have this book on your shelf.
