Very true.
I just thought somebody would appreciate the historical origins of the color.
It is interesting. I think the very word “azure”, through a genesis of spellings and middle eastern languages and then European languages, derived from ‘lapis lazuli’. It seems to me I read how it’s made while reading about dynastic Egyptian history. I think it, among other tints, dyes and pigments, was used for other things besides eye shadow, such as paint in general. The Egyptians developed very vibrant pigments from organic and mineral materials.
So, what poem is your quotation from? I would like to read it.
Thanks.
