The ancestry of the Roman alphabet from Kemetic (Ancient Egyptian hieroglyphs) to Semetic (early Hebrew) to Phoenician to Greek. (J, U, and W were late additions to the Roman alphabet.) The Ancient Egyptian name for their own writing system was "Metu Neter" - meaning divine speech. "Hieroglyphs" is a Greek word - "hieros" means "sacred", "glyph" means writing.
The color amaranthine came from the Greek word ‘amarantos’ which meant unfading. The word Amaranth was used to name an imaginary, undying flower that was, presumably, a deep red-purple color and there you have the two uses of the word today. Lovely stuff.
