rosicrucian
noun[L. ros, dew, and crux, cross; dew, the most powerful dissolvent of gold, according to these fanatics, and cross, the emblem of light.]
The Rosicrucians were a sect or cabal of hermetical philosophers, or rather fanatics, who sprung up in Germany in the fourteenth century, and made great pretensions to science; and among other things, pretended to be masters of the secret of the philosopher’s stone.
