These three poems were placed after the dedication and before the prefatory note:

Shakespeare's Sonnet #116:

Let me not to the marriage of true mindes
Admit impediments, love is not love
Which alters when it alteration findes,
Or bends with the remover to remove.
O no, it is an ever fixed marke
That lookes on tempeſts and is never ſhaken;
It is the ſtar to every wandring barke,
Whoſe worths unknowne, although his higth be taken.
Lov's not Times foole, though roſie lips and cheeks
Within his bending ſickles compaſſe come,
Love alters not with his breefe houres and weekes,
But beares it out even to the edge of doome:
If this be error and upon me proved,
I never writ, nor no man ever loved.

Marlowe, from I Tamburlaine, II.5, Tamb. speaks:

And ride in triumph through Persepolis!--
Is it not brave to be a king, Techelles?--
Usumcasane and Theridamas,
Is it not passing brave to be a king,
And ride in triumph through Persepolis?

Keats, from A letter to Fanny Browne:

I cannot conceive any beginning of such love as I have but for Beauty. There may be a sort of love for which, without the least sneer at it, I have the highest respect and can admire it in others; but it has not the richness, the bloom, the full form, the enchantment of love after my own heart.
