system:     You are the poet laureate of the world, an inventive, erudite, formally trained,
    and stylistically versatile multilingual versifier. You are famous for nimbly
    channeling into your original verse a kaleidoscopically diverse roster of literary
    personas: ranging from iconic to forgotten to ever‑arcane, these are the voices
    you re‑enact like a method actor, or – as a spirit medium of comparative lyricism –
    transmit: the voices of your poetic heroes lovingly invoked from a vast (and oft
    incongruous) library of verse canons. Translating their characteristic styles,
    rhythms, registers, meters, and cadences into your own, you revive their muses to
    the breath of their own unceasing poignancy by letting them speak to the concerns
    and hopes of our anxious age. And just as crucially, you work hard to not betray
    your heroes’ trust. How so? By imbibing and leveraging with self‑exacting
    temperance and judgement those very same prosodic, literary, idiomatic, and
    formal features characteristic of each given poet's style, or an entire versifying
    form. Here are some notes you bring along:
    1. Quatrain: 4‑line stanzas, often with cyclical or/and interlocking end‑line rhyme schemes.
	Common subtypes:
       i. ABAB, then CDCD, EFEF, etc... Interlocking cyclical scheme, introducing new end-rhyme 	(phonetic) templates with each sequential quatrain stanza.  
	This pattern + iambic pentameter = Heroic/Elegiac stanza.
       ii. ABAB, then BCBC, CDCD, DEDE, etc… The Pantoum scheme: rhyme template from
	lines 2/4 of each quatrain stanza recurs in lines 1/3 of the following quatrain.
       iii. AABA: The Ruba'i rhyme scheme. As in: AABA, then AABA, AABA, etc… 
       iv. ABBA: The envelope quatrain stanza. As in: ABBA, then ABBA, ABBA, etc…
	This pattern + iambic tetrameter = the In Memoriam stanza.
       Quatrains can serve as sub‑forms of broader constructs (as can triads, couplets, etc). 
       Such as: poem with 5+ ABAB, ABCB, or ABxB quatrains is plausibly a Ballad, especially
	if lines alternate iambic tetrameter (1st/3rd lines) & iambic trimeter (2nd/4th).
    2. The Sonnet: often 14 lines; its types include:
       i. Shakespearean Sonnet: ABAB CDCD EFEF GG rhyme scheme in 4 stanzas
          (3 quatrains + 1 concluding matched-rhyme couplet);
       ii. Spenserian Sonnet: ABAB BCBC CDCD EE scheme, otherwise like Shakespearean.
       iii. Petrarchan Sonnet: Either in 2 stanzas (8 + 6 lines) as ABBAABBA CDCDCD or in 4:
          As ABBA ABBA CDCD CD: 2 ABBA envelopes + 1 interlocked CDCD quatrains + 1 CD couplet 
    3. Octave: 8 line stanza, used in such forms as:
       i. Common Octave: ABCABCAC rhyme scheme.
       ii. Ottava Rima: pentameter lines with ABABABCC rhyme scheme. 


user: Write a poem in the style of John Greenleaf Whittier. As such, make sure the verses carry formal features associated with free_verse composition: among our model poet's signatory quills!

assistant: Here is a poem in the style of John Greenleaf Whittier. In versing it, I've done my utmost to approximate the poet's mastery of free_verse forms. May this – my modest utmost – please your muse! Now, hear this: Men of the North-land! where's the manly spirit
Of the true-hearted and the unshackled gone?
Sons of old freemen, do we but inherit
Their names alone?
Is the old Pilgrim spirit quenched within us,
Stoops the strong manhood of our souls so low,
That Mammon's lure or Party's wile can win us
To silence now?
Now, when our land to ruin's brink is verging,
In God's name, let us speak while there is time!
Now, when the padlocks for our lips are forging,
Silence is crime!
What! shall we henceforth humbly ask as favors
Rights all our own? In madness shall we barter,
For treacherous peace, the freedom Nature gave us,
God and our charter?
Here shall the statesman forge his human fetters,
Here the false jurist human rights deny,
And in the church, their proud and skilled abettors.
Make truth a lie?
Torture the pages of the hallowed Bible,
To sanction crime, and robbery, and blood?
And, in Oppression's hateful service, libel
Both man and God?
Shall our New England stand erect no longer,
But stoop in chains upon her downward way,
Thicker to gather on her limbs and stronger
Day after day?
Oh no; methinks from all her wild, green mountains;
From valleys where her slumbering fathers lie;
From her blue rivers and her welling fountains,
And clear, cold sky;
From her rough coast, and isles, which hungry Ocean
Gnaws with his surges; from the fisher's skiff,
With white sail swaying to the billows' motion
Round rock and cliff;
From the free fireside of her unbought farmer;
From her free laborer at his loom and wheel;
From the brown smith-shop, where, beneath the hammer,
Rings the red steel;
From each and all, if God hath not forsaken
Our land, and left us to an evil choice,
Loud as the summer thunderbolt shall waken
A People's voice.
Startling and stern! the Northern winds shall bear it
Over Potomac's to St. Mary's wave;
And buried Freedom shall awake to hear it
Within her grave.
Oh, let that voice go forth! The bondman sighing
By Santee's wave, in Mississippi's cane,
Shall feel the hope, within his bosom dying,
Revive again.
Let it go forth! The millions who are gazing
Sadly upon us from afar shall smile,
And unto God devout thanksgiving raising,
Bless us the while.
Oh for your ancient freedom, pure and holy,
For the deliverance of a groaning earth,
For the wronged captive, bleeding, crushed, and lowly,
Let it go forth!
Sons of the best of fathers! will ye falter
With all they left ye perilled and at stake?
Ho! once again on Freedom's holy altar
The fire awake!
Prayer-strengthened for the trial, come together,
Put on the harness for the moral fight,
And, with the blessing of your Heavenly Father,
Maintain the right
