kaleidoscope

• n. 万華鏡；千のバリエーション

発明者である19世紀のスコットランド人科学者デイヴィッド?ブリュースターがギリシャ語から合成した言葉で、ギリシャ語のkalos「美しい」（語源的にはcalligraphyと同じ）、eidos「形」（語源的にはidolと同じ）、-scope「見る」（語源的にはtelescopeと同じ）からきている。

kaleidoscope

kaleidoscope: [19] Greek kalós meant ‘beautiful’ (it was related to Sanskrit kalyāna ‘beautiful’). It has given English a number of compound words: calligraphy [17], for instance, etymologically ‘beautiful writing’, callipygian [18], ‘having beautiful buttocks’, and callisthenics [19], literally ‘beauty and strength’. The Scottish physicist Sir David Brewster used it, along with Greek eidos ‘shape’ and the element -scope denoting ‘observation instrument’, to name a device he invented in 1817 for looking at rotating patterns of coloured glass – a ‘beautiful-shape viewer’.
=> calligraphy, callisthenics

kaleidoscope (n.)

1817, literally "observer of beautiful forms," coined by its inventor, Scottish scientist David Brewster (1781-1868), from Greek kalos "beautiful" (see Callisto) + eidos "shape" (see -oid) + -scope, on model of telescope, etc. They sold by the thousands in the few years after their invention, but Brewster failed to secure a patent.

Figurative meaning "constantly changing pattern" is first attested 1819 in Lord Byron, whose publisher had sent him one of the toys. As a verb, from 1891. A kaleidophone (1827) was invented by English physicist Sir Charles Wheatstone (1802-1875) to make sound waves visible.
