Here is the link for the poem

I just want to know is this poem written. Is it in iambic pentameter or what, and how you classify it?

.Thou large-brained woman and large-hearted man,
Self-called George Sand ! whose soul, amid the lions
Of thy tumultuous senses, moans defiance
And answers roar for roar, as spirits can:
I would some mild miraculous thunder ran
Above the applauded circus, in appliance
Of thine own nobler nature's strength and science,
Drawing two pinions, white as wings of swan,
From thy strong shoulders, to amaze the place
With holier light ! that thou to woman's claim
And man's, mightst join beside the angel's grace
Of a pure genius sanctified from blame
Till child and maiden pressed to thine embrace
To kiss upon thy lips a stainless fame.

Answer 1

It's iambic pentameter - five beats to the line.
example - in the first line the stress is on:
1. large 2.wo 3. and 4. heart 5. man

It's sonnet length (14 lines), but doesn't end with the rhyming couplet most sonnets conclude with.

It' s rhyme scheme is:
A B A B B A A B C D C D C D - with some "off-rhyme" - a decidedly strange pattern.

Ah, confirmation from the web that it IS a sonnet:

Other sonnets

Past and Future (University of Toronto)
Grief
Perplexed Music
On a Portrait of Wordsworth by B. R. Haydon
To George Sand: A Desire
To George Sand: A Recognition

Answer 2

This is actually a sonnet and it is done in iambic pentameter. It's quite easy to identify a sonnet because they usually have 14 lines to them. It's an old form, and you can't usually go wrong if you study the sonnet form and its functions. :)
