Look at the rainbow, and praise him who made it; it is exceedingly beautiful in its brightness. It encircles the sky with its glorious arc; the hands of the Most High have stretched it out. – Bible, Ecclesiasticus (Apocrypha) 43:11-12

In youth, we clothe ourselves with rainbows, and go as brave as the zodiac. In age, we put out another sort of perspiration,—gout, fever, rheumatism, caprice, doubt, fretting, and avarice. – Ralph Waldo Emerson (1803–1882), “Fate,” The Conduct of Life
