I have become quite interested in Surface Decoration, Pattern, Fabric Design, etc. and in doing so, I have been led into a scavenger hunt for design motifs. Everyone is aware that even prehistoric man drew images. I would love to know when man began to reduce his images into motifs–the decorative or ornamental marks that are characteristic of graphic design.
I am not a mathematician; but in beginning to research the origins of decorative marks, I have learned a great deal about Curves from Wikipedia sites that are definitely math-oriented.
I thought that others might also enjoy some of what I have learned.
On the wikipedia site, I discovered that prehistoric spiral-ornamented artifacts have been discovered in Romania. Sprials were also used quite frequently in the architecture and ornamentation of Ancient Greece.
Like other design motifs, the Spiral echoes Nature herself.
