Historic tragedies have their lessons of instruction to after-generations; they tell their sad tales of sorrow and anguish, which make ears tingle and hearts weep in sympathy. They form graphic chapters in the history of our common humanity, however much we may reluctate to own the relationship. The mind almost refuses to believe that the dreadful scenes and tragedies of the French Revolution, so forcibly styled “the Reign of Terror,” occurred in Imperial Paris, the gorgeous capital of France, and the most fashionable emporium of the present modern world, and within the recollection of many persons now living, even among our friends and neighbors.
