The ardent genius and pictorial eye of Gibbon rendered him an incomparable delineator of events; and his powerful mind made him seize the _general_ and characteristic features of society and manners, as they appear in different parts of the world, as well as the traits of individual greatness. His descriptions of the Roman empire in the zenith of its power, as it existed in the time of Augustus--of its decline and long-protracted old age, under Constantine and his successors on the Byzantine throne--of the manners of the pastoral nations, who, under different names, and for a succession of ages, pressed upon and at last overturned the empire--of the Saracens, who, issuing from the lands of Arabia, with the Koran in one hand and the cimeter in the other, urged on their resistless course, till they were arrested by the Atlantic on the one side, and the Indian ocean on the other--of the stern crusaders, who, nursed amid the cloistered shades and castellated realms of Europe, struggled with that devastating horde "when 'twas strongest, and ruled it when 'twas wildest"--of the long agony, silent decay, and ultimate resurrection of the Eternal City--are so many immortal pictures, which, to the end of the world, will fascinate every ardent and imaginative mind. But, not withstanding this incomparable talent for general and characteristic description, he had not the mind necessary for a philosophical analysis of the series of causes which influence human events. He viewed religion with a jaundiced and prejudiced eye--the fatal bequest of his age and French education, unworthy alike of his native candour and inherent strength of understanding. He had profound philosophic ideas, and occasionally let them out with admirable effect; but the turn of his mind was essentially descriptive, and his powers were such, in that brilliant department, that they wiled him from the less inviting contemplation of general causes. We turn over his fascinating pages without ever wearying; but without ever discovering the general progress or apparent tendency of human affairs. We look in vain for the profound reflections of Machiavel on the permanent results of certain political combinations or experiments. He has led us through a "mighty maze;" but he has made no attempt to show it "not without a plan."
