Public speaking has much to do with personalities; naturally, therefore, the narration of a series of biographical details, including anecdotes among the recital of interesting facts, plays a large part in the eulogy, the memorial address, the political speech, the sermon, the lecture, and other platform deliverances. Whole addresses may be made up of such biographical details, such as a sermon on "Moses," or a lecture on "Lee."
The following example is in itself an expanded anecdote, forming a link in a chain:
MARIUS IN PRISON
The peculiar sublimity of the Roman mind does not express itself, nor is it at all to be sought, in their poetry. Poetry, according to the Roman ideal of it, was not an adequate organ for the grander movements of the national mind. Roman sublimity must be looked for in Roman acts, and in Roman sayings. Where, again, will you find a more adequate expression of the Roman majesty, than in the saying of Trajan—Imperatorem oportere stantem mori—that Cæsar ought to die standing; a speech of imperatorial grandeur! Implying that he, who was "the foremost man of all this world,"—and, in regard to all other nations, the representative of his own,—should express its characteristic virtue in his farewell act—should die in procinctu—and should meet the last enemy as the first, with a Roman countenance and in a soldier's attitude. If this had an imperatorial—what follows had a consular majesty, and is almost the grandest story upon record.
Marius, the man who rose to be seven times consul, was in a dungeon, and a slave was sent in with commission to put him to death. These were the persons,—the two extremities of exalted and forlorn humanity, its vanward and its rearward man, a Roman consul and an abject slave. But their natural relations to each other were, by the caprice of fortune, monstrously inverted: the consul was in chains; the slave was for a moment the arbiter of his fate. By what spells, what magic, did Marius reinstate himself in his natural prerogatives? By what marvels drawn from heaven or from earth, did he, in the twinkling of an eye, again invest himself with the purple, and place between himself and his assassin a host of shadowy lictors? By the mere blank supremacy of great minds over weak ones. He fascinated the slave, as a rattlesnake does a bird. Standing "like Teneriffe," he smote him with his eye, and said, "Tune, homo, audes occidere C. Marium?"—"Dost thou, fellow, presume to kill Caius Marius?" Whereat, the reptile, quaking under the voice, nor daring to affront the consular eye, sank gently to the ground—turned round upon his hands and feet—and, crawling out of the prison like any other vermin, left Marius standing in solitude as steadfast and immovable as the capitol.

Here is a similar example, prefaced by a general historical statement and concluding with autobiographical details:
A REMINISCENCE OF LEXINGTON
One raw morning in spring—it will be eighty years the 19th day of this month—Hancock and Adams, the Moses and Aaron of that Great Deliverance, were both at Lexington; they also had "obstructed an officer" with brave words. British soldiers, a thousand strong, came to seize them and carry them over sea for trial, and so nip the bud of Freedom auspiciously opening in that early spring. The town militia came together before daylight, "for training." A great, tall man, with a large head and a high, wide brow, their captain,—one who had "seen service,"—marshalled them into line, numbering but seventy, and bade "every man load his piece with powder and ball. I will order the first man shot that runs away," said he, when some faltered. "Don't fire unless fired upon, but if they want to have a war, let it begin here."
Gentlemen, you know what followed; those farmers and mechanics "fired the shot heard round the world." A little monument covers the bones of such as before had pledged their fortune and their sacred honor to the Freedom of America, and that day gave it also their lives. I was born in that little town, and bred up amid the memories of that day. When a boy, my mother lifted me up, one Sunday, in her religious, patriotic arms, and held me while I read the first monumental line I ever saw—"Sacred to Liberty and the Rights of Mankind."
