As far back towards the infancy of our race as history and tradition are able to conduct us, we have found the custom everywhere prevailing among mankind, to mark by some striking exhibition, those events which were important and interesting, either in their immediate bearing or in their remote consequences upon the destiny of those among whom they occurred. These events are epochs in the history of man; they mark the rise and fall of kingdoms and of dynasties; they record the movements of the human mind, and the influence of those movements upon the destinies of the race; and whilst they frequently disclose to us the sad and sickening spectacle of innocence bending under the yoke of injustice, and of weakness robbed and despoiled by the hand of an unscrupulous oppression, they occasionally display, as a theme for admiring contemplation, the sublime spectacle of the human mind, roused by a concurrence of circumstances, to vigorous advances in the career of improvement. The utility of thus marking the progress of time--of recording the occurrence of events, and of holding up remarkable personages to the contemplation of mankind--is too obvious to need remark. It arises from the instincts of mankind, the irrepressible spirit of emulation, and the ardent longings after immortality; and this restless passion to perpetuate their existence which they find it impossible to suppress, impels them to secure the admiration of succeeding generations in the performance of deeds, by which, although dead, they may yet speak. In commemorating events thus powerful in forming the manners and sentiments of mankind, and in rousing them to strenuous exertion and to high and sustained emulation, it is obvious that such, and such only, should be selected as virtue and humanity would approve; and that, if any of an opposite character be held up, they should be displayed only as beacons, or as towering Pharos throwing a strong but lurid light to mark the melancholy grave of mad ambition, and to warn the inexperienced voyager of the existing danger.
