Many varieties of sonnet, of course, have been written over the ages.

I think it's cyclical. Zombies have been around for ages, and vampires have run their course; we've had so many vampire movies.

There has been so much rubbish written up in the papers over the years.

How do I love thee? Let me count the ways.
I love thee to the depth and breadth and height
My soul can reach, when feeling out of sight
For the ends of being and ideal grace.
I love thee to the level of every day's
Most quiet need, by sun and candle-light.
I love thee freely, as men strive for right.
I love thee purely, as they turn from praise.
I love thee with the passion put to use
In my old griefs, and with my childhood's faith.
I love thee with a love I seemed to lose
With my lost saints. I love thee with the breath,
Smiles, tears, of all my life; and, if God choose,
I shall but love thee better after death.

I don’t think that I’ve been in love as such
Although I liked a few folk pretty well
Love must be vaster than my smiles or touch
for brave men died and empires rose and fell
For love, girls follow boys to foreign lands
and men have followed women into hell
In plays and poems someone understands
there’s something makes us more than blood and bone
and more than biological demands
For me love’s like the wind, unseen, unknown
I see the trees are bending where it’s been
I know that it leaves wreckage where it’s blown
I really don’t know what "I love you" means
I think it means "don’t leave me here alone

Sonnet XVII

I do not love you as if you were salt-rose, or topaz,
or the arrow of carnations the fire shoots off.
I love you as certain dark things are to be loved,
in secret, between the shadow and the soul.

I love you as the plant that never blooms
but carries in itself the light of hidden flowers;
thanks to your love a certain solid fragrance,
risen from the earth, lives darkly in my body.

I love you without knowing how, or when, or from where.
I love you straightforwardly, without complexities or pride;
so I love you because I know no other way than this:

where I does not exist, nor you,
so close that your hand on my chest is my hand,
so close that your eyes close as I fall asleep.
