Why is gold called Gold?

The term “Gold” as we know it today, actually derives from Old English and Germanic origins. The chemical symbol for Gold on the periodic table of elements is AU. This symbol is a tribute to the Latin word, aurum, loosely translated “glowing dawn” which was used to describe gold in Ancient Rome.
