> The words for "beautiful", "fair", "bright", "shining", "well-reputed", "righteous" have a long history of being related

Compare modern Mandarin 漂亮 ["beautiful", in most of the English senses of the word] and 亮 ["shine"].

Also, I just realized that Finnish loistava can mean either "excellent" or "shining", "radiant". Of course English also has, for instance, the phrase "shining example".
