But I am constant as the northern star,

Of whose true-fix'd and resting quality

There is no fellow in the firmament.

William Shakespeare (1564-1616): Julius Caesar. Act iii. Sc. 1.

Friendship is constant in all other things

Save in the office and affairs of love:

Therefore all hearts in love use their own tongues;

Let every eye negotiate for itself

And trust no agent.

Still constant is a wondrous excellence.

O heaven! were man

But constant, he were perfect.

William Shakespeare (1564-1616): The Two Gentlemen of Verona. Act v. Sc. 4.

To sorrow

I bade good-morrow,

And thought to leave her far away behind;

But cheerly, cheerly,

She loves me dearly;

She is so constant to me, and so kind.

Sigh no more, ladies, sigh no more,

Men were deceivers ever,—

One foot in sea and one on shore,

To one thing constant never.

William Shakespeare (1564-1616): Much Ado about Nothing. Act ii. Sc. 3.

Sigh no more, ladies, sigh no more!

Men were deceivers ever;

One foot in sea and one on shore,

To one thing constant never.

Thomas Percy (1728-1811): The Friar of Orders Gray.
