saturn

Before Saturn became a marble-colored dot in a telescope, he was a god with muddy hands. Romans imagined Saturn as the ancient instructor of agriculture, a civilizing figure tied to the golden age, and poets loved to place his reign in a lost, happier world. Later astronomers kept the name for the slow, farthest planet they could see with the naked eye, as if distance itself deserved a dignified old god. There was even a tempting folk etymology linking Saturn to Latin serere, "to sow," which fit the farming story so neatly that people happily repeated it, even though the name may instead go back to an older Italic or even Etruscan source. Then alchemists adopted Saturn for lead in the late Middle Ages, because lead feels heavy, dull, and old enough to have watched the world begin. One name, and you get agriculture, astronomy, and alchemy all packed into a single cold ringed planet.
