The glorious sun
Stays in his course, and plays the alchemist;
Turning with splendor of his precious eye,
The meager cloddy earth to glittering gold (sweet).
—King John: Shakespeare
From Nature’s magic hand whose touch makes sadness
Eventual gladness,
The reverent moral Alchemist may learn
The art to turn
Fate’s roughest, hardest, most forbidding dross,
Into the metal gold that knows not change or loss.
—Horace Smith
