“The truly good and wise man will bear all kinds of fortune in a seemly way, and will always act in the noblest manner that the circumstances allow.”

The V-a-s-e, reported in Bartlett's Familiar Quotations, 10th ed. (1919).

Original: (it) E però un principe savio deve pensare un modo per il quale i suoi cittadini sempre ed in ogni modo e qualità di tempo abbiano bisogno dello Stato di lui, e sempre poi gli saranno fedeli.

A donna né bellezza,
Né nobiltà, né gran fortuna basta,
Sì che di vero onor monti in altezza,
Se per nome e per opre non è casta.
Canto XLIII, stanza 84 (tr. B. Reynolds)

Valence of Prince Berthold, in Act IV.
Colombe's Birthday (1844)
Context: p>He gathers earth's whole good into his arms;
Standing, as man now, stately, strong and wise,
Marching to fortune, not surprised by her.
One great aim, like a guiding-star, above—
Which tasks strength, wisdom, stateliness, to lift
His manhood to the height that takes the prize;
A prize not near — lest overlooking earth
He rashly spring to seize it — nor remote,
So that he rest upon his path content:
But day by day, while shimmering grows shine,
And the faint circlet prophesies the orb,
He sees so much as, just evolving these,
The stateliness, the wisdom and the strength,
To due completion, will suffice this life,
And lead him at his grandest to the grave.
After this star, out of a night he springs;
A beggar's cradle for the throne of thrones
He quits; so, mounting, feels each step he mounts,
Nor, as from each to each exultingly
He passes, overleaps one grade of joy.
This, for his own good: — with the world, each gift
Of God and man, — reality, tradition,
Fancy and fact — so well environ him,
That as a mystic panoply they serve —
Of force, untenanted, to awe mankind,
And work his purpose out with half the world,
While he, their master, dexterously slipt
From such encumbrance, is meantime employed
With his own prowess on the other half.
Thus shall he prosper, every day's success
Adding, to what is he, a solid strength —
An aery might to what encircles him,
Till at the last, so life's routine lends help,
That as the Emperor only breathes and moves,
His shadow shall be watched, his step or stalk
Become a comfort or a portent, how
He trails his ermine take significance, —
Till even his power shall cease to be most power,
And men shall dread his weakness more, nor dare
Peril their earth its bravest, first and best,
Its typified invincibility.Thus shall he go on, greatening, till he ends—
The man of men, the spirit of all flesh,
The fiery centre of an earthly world!</p

Epistulae Morales ad Lucilium (Moral Letters to Lucilius), Letter LXXXV: On Some Vain Syllogisms

Conversation with Emmanuel, comte de Las Cases (11 November 1816), Mémorial de Sainte Hélène, v. 4, p. 133 http://books.google.com/books?id=945jAAAAMAAJ&amp;pg=PA133. <br class="br">Context: I may have had many projects, but I never was free to carry out any of them. It did me little good to be holding the helm; no matter how strong my hands, the sudden and numerous waves were stronger still, and I was wise enough to yield to them rather than resist them obstinately and make the ship founder. Thus I never was truly my own master but was always ruled by circumstances.
