“My friend, let us dedicate our souls to the Fatherland with wonderful impulses!” Analysis of the poem “to Chaadaev”.

The theme of freedom continues in other poems of the poet, but the most striking and significant of the youthful freedom-loving works is “To Chaadaev” (1818).

Pyotr Yakovlevich Chaadaev is one of the brightest and most remarkable personalities of Pushkin’s era.
Pushkin and Chaadaev met in 1816 in the Karamzin house. Chaadaev is 22 years old, he is a cornet of the Life Guards Hussar Regiment, covered in the glory of the battles of the War of 1812, who reached Paris with the Russian army. Pushkin is a lyceum student, he is 17 years old. They quickly became close and, despite the age difference, became friends, and then friends. Pushkin admired Chaadaev, absorbed his freedom-loving speeches like a sponge, and drew his friend in the margins of his manuscripts.

This is the person to whom one of the best poems Pushkin.
Let's read it.

What does it sound like? What intonations predominate in it?

The poem sounds upbeat, solemn, it inspires to fight for the happiness of the Fatherland, calls to serve it. It is this high call that is the leading intonation of the work.

In what ways is the poem “To Chaadaev” consonant with the ode “Liberty”? What images of him resonate with her?

Both “To Chaadaev” and “Liberty” are devoted to the same theme, and in both works there is a passionate call to the fight for freedom:
"Tyrants of the world! Tremble! / And you, take heart and listen, / Arise, fallen slaves.”

“While we are burning with freedom, / While our hearts are alive for honor, / My friend, we will dedicate our souls to the Fatherland’s beautiful impulses!”

Many of the images in them have something in common: “an autocratic villain” - “the wreckage of autocracy”, “Holy liberty”, -unjust power” - “under the yoke of fatal power.”

Which of these images, in your opinion, is the leading image in the poem “to Chaadaev”? This is “Holy Liberty”, which the Fatherland and the lyrical hero of the poem crave; he awaits it “with languid hope.”

How do you see this “Liberty”? Draw a verbal portrait of her.

Ninth graders often draw the image of a young girl in a white dress standing on top of some cliff or rock. The wind blows her loose hair and flutters her dress. Clouds are rushing over the girl’s head, illuminated by the rays of the sun, and at the foot of the cliff the sea is raging...

What do you think in Pushkin’s poem suggested the image of a girl to you?

Yes, the very feeling of the poet, who is impatiently waiting for a meeting with “Holy Liberty,” “like a young lover awaits / The minutes of a faithful date.” He associates liberty with his beloved.

What does this comparison of the poet make you think about?

Liberty is desired for him just like his beloved: it evokes languor, trembling, hope in his heart...
How are the images of Liberty and the Fatherland connected in the poem?

The Fatherland calls for help (“Let us heed the call of the Fatherland”) because it suffers “under the yoke of fatal power,” it is waiting for liberation from it, waiting for “Holy Liberty.”

Freedom is what she needs, like air, like bread, like water... Think about the poet’s invoking words, full of youthful strength:
While we are burning with freedom,
While hearts are alive for honor,
My friend, let's dedicate it to the Fatherland
Beautiful impulses from the soul!

In what sense is the word “honor” used here?

Honor here is synonymous with conscience - an internal call to goodness, denial of evil, nobility. If “hearts are alive for honor,” it means that you will not remain indifferent to the fate of the Fatherland, which means you will join the battle for its freedom.

And thanks to the common efforts of the faithful sons of the Fatherland, the “star of captivating happiness” will certainly rise over Russia, that is, it will become free, only “debris” will remain from the autocracy, on which the names of those who
dedicated “the beautiful impulses of his soul” to the Fatherland.

Please note that this poem seems to be framed by the motif of a dream:
“youthful fun has disappeared, like a dream ...” and “Russia will awaken from sleep ...”,
What is the meaning of this motif at the beginning of the poem and what is it at the end?

At the beginning, the dream is an illusion associated with the hope for change, which ardent young hearts await “with languid hope.” In the end, the dream is associated with the centuries-old torpor of Russia in the shackles of slavery - serfdom, and it is from this torpor that the country must rise. The illusion of “quiet glory”, a peaceful appeal to justice dissipates, “like a dream, like morning fog”, the “calling of the Fatherland” becomes more audible.

It is those who hear this “calling” who are able to destroy Russia’s centuries-old sleep and return it to a free, full life.

Consider G. Klodt’s illustration for Pushkin’s poem “To Chaadaev.” What does it remind you of?(Emblem, coat of arms.)

PHOTO
Decipher the symbols of this emblem: the torch is a symbol of freedom burning in the chest of the lyrical hero, the chains are a symbol of slavery, the scrolls symbolize the poetic word, a call to action and at the same time their outlines resemble a lyre.

Why do you think the artist chose this style?

The poem itself is in many ways akin to the emblem of freedom fighters, this is evidenced by the images-symbols, images-emblems that we find in the work.

In the coat of arms and emblem, all symbols have their own meaning, carry a certain idea, they themselves unfold only when you look at them; Likewise, in Pushkin’s poem, images - symbols do not require explanation; they themselves lead both the visual and semantic series, suggesting thoughts, actions, deeds.

That is why this poem was so loved by the future Decembrists, and that is why copies of it were found on almost all those arrested in connection with the uprising.

ANOTHER ANALYSIS

This poem is one of the most famous
political works of Alexander Sergeevich
Pushkin. It is written in the genre of a friendly message -
nia. In the 19th century it was a common literary
tour genre, which Pushkin often turned to
co. A friendly message implies the utmost
sincerity, but this does not mean at all that poetry
the creation was created only for the named person - it
addressed to a wide range of readers.
It is known that Pushkin did not plan to publish
message “To Chaadaev”. However, the poem
recorded from the words of the poet during reading in a narrow
circle of friends, began to be passed from hand to hand
and soon became widely known, although omitted
it was highlighted only in 1829. Thanks to
the author gained the reputation of a freethinker, and
the poem is still called literary
anthem of the Decembrists.
The poem is addressed to one of the remarkable
neyshik people of his time and a close friend
Pushkin - Pyotr Yakovlevich Chaadaev. At 16 years old
Chaadaev joined the Semenovsky Guards Regiment, with
which he traveled from Borodino to Paris. In 1818
the year when the poem was written, he served
in the Life Guards Hussar Regiment, later became famous
great philosopher and publicist. It was for Pushkin
an example of commitment to liberation ideas
(in 1821 Chaadaev became a member of the secret Decembrist
social society "Union of Prosperity").
in the first lines of the message “To Chaadaev” contains
there is a hint of the carefree youth of two young
of people. Peaceful pleasures and fun, hopes
Fortunately, dreams of literary fame bound the friends together:

Love, hope, quiet glory
Deception did not last long for us,
The youthful fun has disappeared
Like a dream, like morning fog...
The epithet quiet (glory) indicates that
friends dreamed of quiet, peaceful happiness. Talking about
that “young fun” has disappeared, Pushkin cites
a capacious and vivid comparison: “like a dream, like a morning
fog". And in fact, neither from sleep nor from morning
there is nothing left of the fog.
There is obvious disappointment in these lines
reign of Alexander 1. It is known that the first
the steps of the young emperor inspired his subjects
hope that his reign will be liberal
(Alexander 1 even discussed with his closest friends -
our plans for transforming Russia into a constitutional
monarchy), but this hope was not justified.
In conditions of political oppression and lack of rights, the “quiet
glory" was simply impossible.
Then the poet says: “We are waiting for... a moment of freedom-
ity of the saint ", the epithet of the saint testifies
about the high understanding of “liberty”. Comparison:
“How a young lover waits / For faithful minutes
dates,” emphasizes the poet’s passionate desire
wait for “holy freedom” And even confidence in
making this happen (sure date).
The poem contrasts two images:
“fatal power” and “fatherland”:
Under the yoke of fatal power
With an impatient soul
Let us heed the calling of the Fatherland.
The epithet fatal gains more power
(power) - cruel, inhuman. And the poet's homeland
calls her father; choosing from a range of synonyms
the most intimate and soulful meaning.
It is important to note that the poet speaks not only about his
feelings - it expresses the thoughts and desires of many
their like-minded people: “But there’s still something burning inside us -
Lanier"; “We wait with languid hope,”
What does the “star of captivating happiness” mean?
which one should rise? In political vocabulary
of that era, the word “star” often symbolized
revolution, and the rising of a star - victory in liberation
body struggle. No wonder the Decembrists Kondraty
Ryleev and Alexander Bestuzhev named their al-
manah "North Star". Of course, Pushkin did not
accidentally chose this word in a message addressed to
to your friends.
Addressing the reader with a fiery appeal:
“My friend, let’s dedicate / Beautiful souls to the fatherland
impulses,” the poet expresses confidence that
“Russia will awaken from sleep, / And on the ruins of self-government -
stya / / They will write our names!”, The words “the wreckage of sa-
autocracy" means the coming fall of the autocracy
viya. The poet calls for selfless service
homeland, to the fight for freedom. For him, the concepts of “pa-
triotism" and "freedom" are inseparable from each other. But
Pushkin understands that he will voluntarily make concessions
the king will not agree. That is why in recent

WOLVERINE

Wolverine - carnivorous mammal of the mustelid family, a representative of the genus Gulo, translated from Latin as “glutton”. Wolverines weigh from 10 to 25 kg, females are about 10% smaller and 30% lighter than males. The wolverine's body length is up to 1 meter. Externally, the wolverine resembles a dwarf bear or badger. Its body is squat, its paws are short with large claws.

The feet are disproportionately large - 10 cm wide and 9 cm long, which allows the wolverine to easily move through deep, loose snow. This plantigrade behavior gives the wolverine an even greater resemblance to a clubfooted bear.

The wolverine's teeth are powerful and have sharp edges. The hair is thick, long, and coarse. The fur color of the wolverine is brown or brown-black.

The wolverine is common in the taiga and forest-tundra of Eurasia and North America. Usually the wolverine lives alone, zealously defending the boundaries of its territory from individuals of its own sex. Unlike most mustelids, which lead a sedentary lifestyle, the wolverine constantly wanders in search of prey in its “individual area.” It is surprisingly hardy and usually travels up to 45 km per day. Outwardly, it seems that wolverine is clumsy and clumsy. This is a dangerous misconception. Wolverine is strong and can kill a deer single-handedly. She easily climbs trees, has sharp eyesight, hearing and excellent sense of smell. This allows her to find carrion under a layer of snow. Wolverine is omnivorous. Its diet includes: hares, rodents, eggs, black grouse, fish, insect larvae, berries. Often the wolverine steals prey from traps and ruins the winter quarters of hunters. It can eat leather bindings on skis at night, chew through the wall of a food box and completely eat its contents. But the wolverine should not be considered a voracious and useless animal. She is a nurse, destroying sick, weakened animals, and does not allow contagious diseases to spread among animals. Once every two years, wolverines have offspring: two or three blind cubs that open their eyes only five weeks after birth. The mother is solely responsible for raising the offspring. Wolverine cubs taken from nature become accustomed to humans and become completely tame.

The skin consists of epidermis, dermis and subcutaneous fat.

The cells of the inner layers of the epidermis are constantly dividing, while the middle layers are filled with keratin (keratinized). The outer cells of the epidermis are dead and gradually fall off, taking away microbes and fungi with them. In inner layer the pigment melanin is formed, which blocks the ultraviolet rays of the sun and gives the skin color, as well as vitamin D.

Dermis contains

  • receptors and nerves - provide skin sensitivity
  • blood capillaries- serve as a blood depot and regulate heat transfer (it increases when the carillaries expand)
  • sweat glands secrete sweat (water, salts, urea); As sweat evaporates, the body cools down
  • sebaceous glands - secrete sebum, which lubricates and gives elasticity to the epidermis and hair
  • hair follicles - contain
    • living part of hair
    • sebaceous gland
    • nerve ending
    • muscle that lifts the hair (contracts in cold weather, “goosebumps” appear on the skin)

Subcutaneous fatty tissue softens mechanical stress, reduces heat transfer, and stores fat.
