Critical Analysis of Antony and Cleopatra. Act V, Scene 2-...

Cleopatra is one of the Shakespeare’s strongest and awe inspiring female characters. She is complex and decidedly inconstant, yet she is never less than her self: passionate, grand and over the top. By killing her self Cleopatra remains her truest, reserving all her greatness and mocking over Caesar’ triumph. Cleopatra is beyond neat categories and tidy synopses. Throughout the course of the play she dons many roles of hussy, enchantress, queen, tyrant, strew and mother. Her character has been as shifting as the clouds that Antony describes in Act IV, scene xv. Despite Romans’ victory she does not allow her multifaceted identity to be stripped to one of its simplest, basest components. Thus she refuses to parade through the filthy†¦show more content†¦Even in death she remains once again of her female power. Understandably the victorious Caesar is forced to admire her when he sees her dead body:†Ã¢â‚¬ ¦she looks like sleep/As she would catch another Antony/ in her strong toil of grace† (v.ii.345-7). The death of Cleopatra, which closes the play, is greeted by the reader with sympathy and admiration, even with exultation at the thought that she has foiled Ceasar. While Antony’s death rouses a strong feeling of pity, at the death of Cleopatra this feeling seems to be entire lacking. †Triumph†, â€Å"exultation†, â€Å"wonder†, are the words most commonly used to describe the feelings evoked by the last scene. Her death is so glorious as to be triumph, the final mood in Antony and Cleopatra is triumphant. The play ends with serenity, not with pain, but with grandeur. [Ernest Schanzer, The problems of Shakespeare] The end of Shakespeare’s play Antony and Cleopatra suggests that Caesar might have won the political victory but not moral one. Octavius will become Augustus, the great ruler of the Roman Empire. But Cleopatra’s assessment is partially true. Octavius is known in history as the agent of Rome’s transformation into Empire, but the poet’s natural subject is Cleopatra. Because she captures the imaginations of writers like Shakespeare, her name has ultimately even more famous than that of her

The Idea Of A Supernatural - 1323 Words

Someone once said â€Å"The whole point of knowledge is to produce both meaning and purpose in our personal lives.† The reason one might establish this idea is because since one was a child, he or she was forced to live in a certain culture and conform to its ideas. As we grow older, we begin to ask ‘what is the reason to live under these rules in this world?’ That is where religion took its role. To have a reason, or an idea, for the purpose of life, we used the idea of a supernatural being(s) to confirm our purpose. We gather knowledge of religion to establish the idea that we would be able to live closer to the supernatural. Buddhism, although not technically a religion, but a philosophy, is a significant supernatural realm in which people tend to endeavor to reach ultimate meaning and purpose into life. Buddhism’s main focus is to use the knowledge that the world has to offer and use to to reach nirvana - the purpose for life. Siddhartha Gautama was bor n into a rich life under the King and Queen. He was able to live with the royalties and also be treated like one. The king, his father, didn’t allow Siddhartha to go into the outside world to be exposed into the negativities of life. One day, Siddhartha was desired to see the outside, as he did so, secretly. On this journey, he came to head with a sick person, a dead person, and an old person. This became to be known as the three evils. This allowed Siddhartha to understand the concept of universal suffering.

Garcia Lorca Poet Of The Anda Essay free essay sample

Garcia Lorca: Poet Of The Anda Essay, Research Paper Garcia Lorca Poet of the Andalusians Federico Garcia Lorca is one of Spain s most celebrated creative persons. He played a big function in transforming the Spanish theater of the 20th century. In add-on to his original plants for the theaters in Barcelona and Madrid, the going university theater he directed, La Baracca, brought authoritative Spanish play to audiences throughout rural Spain. Before his executing by the Fascists in 1936, he had amassed a big organic structure of work. His last three dramas established Lorca s international repute as a dramatist. Born in a little town near the metropolis of Granada in Southern Spain in the Andalusian Mountains, he was profoundly influenced by the Gypsy and Arabic civilization at that place. His male parent was a comfortable husbandman, his female parent a extremely educated school instructor. From the beginning it was she who nurtured his musical and poetic endowments. ( Honig 2 ) He left place for the University of Granada at the age of 16 to gain a grade in jurisprudence. A second-rate pupil, he was frustrated by topics he did non instantly appreciation. He cut many categories, preferring alternatively to seek the company of literary work forces, write poetry into the bitty hours of the forenoon, and play piano in dark nines for hours on terminal. ( Stainton ) While in Granada he met Fernando de los Rios, a professor at the university and an of import political figure, who became his wise man. Following Rios advice, Lorca left Granada for Madrid in 1919. He lived at the Residencia de Estudantes, a Spanish version of Oxford, where the ambiance was serious and scholarly. ( Duran 3 ) It was here he became close friends with the celebrated Salvador Dali, Gerardo Diego, a poet, and Luis Bunuel, who would subsequently go a great movie manager. In 1929 he traveled to New York, where Fernando de los Rios arranged for him to attend Columbia University for a short piece. He was in the throes of a cryptic emotional crisis, the inside informations of which have neer been disclosed. He returned to Spain in 1931 much changed by his experiences in America. He had a passionate involvement in American movie and wind, and a captivation with the adult females in New York, who were so different from those in Spain. ( Duran 9 ) His stay in America seems to be an of import turning point in his metabolism from poet to dramatist. Upon his return, he turned his attending to the phase, establishing the theater company La Barraca. He traveled overseas once more to bring forth authoritative Spanish dramas in Montevideo and Buenos Aires. In 1934 he returned to Madrid, where he concentrated on playwrighting. These following few old ages before his decease are considered his mature period, when he wrote his rural play, Bodas de Sangre, Yerma, and La Casa de Bernarda Alba. These are concentrated on a individual subject ; the agony and the defeat of the Spanish adult female. Blood Wedding The crisis of this drama is the contrast between the two contradictory rule lines of action. One is towards the nuptials of the bride and bridegroom ; a socially sanctioned brotherhood between a adult male and a adult female necessary for the accretion of land and belongings, and for transporting on the household blood line. The 2nd line of action is toward the consummation of an illicit love matter between the bride and Leonardo, which pays no attentiveness to material limitations or societal conditions. ( Anderson 91 ) The bride s battle between responsibility to her household and her duty to get married, and her desire for Leonardo become the focal point of dramatic involvement as the motion of the lines of action come to a flood tide in the 2nd act. The female parent the 2nd focal point of dramatic involvement. She has lost both her hubby and her boy in a knife battle with the Felix kin. She has a horror of arms, and feels that the liquidators have non been punished plenty for their offenses. The female parent consents to her boy s marrying the interest of his felicity, despite a feeling of apprehensiveness towards the bride. Her hatred towards the rival kin and her intuition of the bride set up a sense of impending calamity in the first minutes of the drama. ( Anderson 92 ) Each of the three scenes in act one reveals the drama s tragic potency. The first scene is concerned with the female parent s reserve towards her boy s nuptials, in contrast to his optimism and avidity to be wed. The 2nd scene takes topographic point in Leonardo s house. He grows sullen when he learns of the bride s battle, and becomes hostile towards his mother-in-law when she asks him where he s merely come from. He eventually erupts in choler and storms out of the house, waking the babe. In the 3rd scene the female parent and bridegroom and the male parent and bride all come together and the matrimony is arranged. In the last half of the scene merely the bride and the retainer are onstage. The bride becomes violent when the retainer asks her about her nuptials gift, she bites and shoves and cries, and the servant forces her to acknowledge that Leonardo has been sing her in secret at dark. With these struggles set into topographic point, the 2nd act brings us to the nuptials twenty-four hours. Lorca s primary accent is on the line of action towards the completion of the nuptials. Underneath this he builds the possible contradictory motion of action until it overwhelms the chief impulse and replaces it with a new and doomed motion towards the brotherhood of the two lovers. ( Anderson 95 ) During the nuptials response the bride and Leonardo flight together, his married woman sees them, on his Equus caballus, with their weaponries around each other, they rode off like a hiting star! ( Three Tragedies 77 ) After detecting that her frights have about the nuptials have come true, the female parent finds herself lacerate between the fright of losing her boy to the same Felix kin, and the importance of keeping her household s award by retaliation. Travel! After them! No! she calls, Don t travel. These people kill rapidly and good # 8230 ; but yes, run, and I ll follow. The hr of blood has come once more. ( Three Tragedies 77-8 ) In the concluding act, there is a displacement from prose to versify. Three woodcutters enter, a traditional tragic chorus. A mendicant adult female appears, Death in camouflage, naming for the Moon to light the forests so that she might seek her victims. For a minute the scene focal points on the lovers. Accepting the calamity and inevitableness of their state of affairs, they incrimination non themselves but the blind lusts which the Earth has created in them. ( Honig 158 ) Suddenly there are two screams, the challengers have killed each other, and the foreordained calamity has eventually been played out. The three adult females brought together in the concluding scene symbolically go one. The scene depicts a symbolic declaration ; they mourn together, united in their heartache, but are isolated by their ain single experiences. These three adult females ; a little representational group of the female functions of female parent, girl, lover, bride, married woman, embody the invariable fates of all adult females. Without their hubby, male parents, and boies, they are nil. ( Anderson 101 ) Yerma Yerma is the 2nd drama in Lorca s trilogy. His statements about Yerma indicate that he was seeking a pureness of signifier about his construct of calamity. Yerma is a calamity. From the get downing the audience will acknowledge that something formidable is traveling to go on. . . .What does go on? Yerma has no secret plan. Yerma is a character who develops over the class of the six scenes that compromise the play. As befits a calamity, I have included in Yerma a chorus that remarks on the subject of the calamity, which is its existent substance. Notice that I have said subject, I repeat that Yerma has no secret plan. At several points the audience will believe that there is one, but it will be a little semblance. . . . Unlike the heroines in the other two dramas, Yerma s calamity is non in strife with her society. She has accepted her ordered matrimony with a sense of responsibility which is merely as strong as her desire to hold kids. ( Anderson 106 ) Her felicity, hence, lies entirely in the custodies of her hubby Juan ; a pale waste adult male who is blind to his married woman s anguish. The tragic contradiction of this drama is exemplified in one individual character and her heroic battle against the loss of her sense of ego. The first act is comprised of her brushs with three characters, each proposing a new manner of seeing the calamity of Yerma s childless matrimony. The first, Maria, is a immature pregnant adult female who s artlessness contrasts Yerma s cognition. The 2nd, Victor, is the fine-looking shepherd who is clearly Yerma s natural mate. There are allusions to a possible harmoniousness between them, the illusory secret plan Lorca mentioned. The 3rd character is the old adult female who has borne 14 kids. Her natural birthrate, in resistance to Yerma s waste province gives her a natural easiness with life in general. The choral scene in the 2nd act is full of music and colour as six washwomans sing and chitchat by a mountain watercourse. Unlike the antic forest scene in Blood Wedding, this choral scene is wholly plausible. They speculate about Yerma s sadness, and her attractive force to Victor. They besides introduce the allegations of incrimination, which remain unsolved, for Yerma and Juan s continue asepsis. ( Honig 174 ) Five old ages base on balls between Acts of the Apostless one and two. Yerma has now been married for seven old ages. She has grown progressively defeated and despairing in her childless matrimony, and feels humbled by the birthrate all around her. Her character evolves to its darkest stage in act three when Yerma visits the sorceress. She spends the dark in birthrate rites, and when the sorceress prays over her and tells her to seek safety in her hubby s weaponries, Yerma reveals that there is no familiarity in their matrimony ; she is repelled by sex yet wants that she might experience sexual passion if it will give her kids. Juan, nevertheless, does non suffer from their failure to gestate, and Yerma resents his peace: The problem is he doesn t want kids! # 8230 ; I can state that in a glimpse, and, since he doesn T want them, he doesn T give them to me, and yet he s my lone redemption. By award and by blood. My merely redemption. ( Three Tragedies 140 ) There is no solution to Yerma s childlessness. When the old adult female offers her boy to Yerma, she is outraged at the corruption of such a suggestion. Make you conceive of I could cognize another adult male? Where would that go forth my award? # 8230 ; On the route I ve started I ll stay # 8230 ; Mine is a sorrow already beyond the flesh. ( Three Tragedies 151 ) Yerma s climaxing act of strangulating Juan with her bare hands represents her ain self-destruction, and the decease of the kid she will neer hold. But this act besides releases her from her agony. Barren, waste, but certain: now I truly know for certain # 8230 ; Now I ll sleep without galvanizing myself awake, dying to see if I feel in my blood another new blood. My organic structure, dry everlastingly! ( Three Tragedies 153 ) The House of Bernarda Alba The House of Bernarda Alba is Lorca s most profound part to the phase. Lorca departs from his usual lyricality and choruses found in his first two calamities and dressed ores on pragmatism, mentioning to the drama as a photographic papers. ( Three Calamities 156 ) He is said to hold exclaimed after a reading of the manuscript to a group of friends, Not a individual bead of poesy! World! Realism! The rubric refers to Bernarda Alba s house, which is the incarnation of parturiency that affects the characters throughout the action of the drama. Bernarda s laterality over her five girls, female parent and retainers reaches an extreme after the decease of her hubby, and physiques steadily over the class of three Acts of the Apostless. As a materfamilias, she guards the award of her household like a hawk, ever cognizant that her neighbours eyes are on them. She declares, For the eight old ages of bereavement, non a breath of air will acquire in this house from the street # 8230 ; That s what happened in my male parent s house # 8211 ; and in my gramps s house. The misss all yearn for one adult male, Pepe el Romano, the eldest girl s fianc and the youngest girl s secret lover. Like in Blood Wedding and Yerma an arranged matrimony and its deformation of values and relationships is the secret plan device Lorca uses to impel the action towards calamity. ( Anderson 122 ) As the youngest and most attractive girl, Adela suffers the most from her parturiency ; she is driven by an titillating energy that is focused entirely on one adult male, who will get married her sister for her wealth. She clashes with the family retainer La Poncia and with her sister Martirio who both attempt to maintain her from go oning her matter. Unlike the lover s ecstatic flight in Blood Wedding, Adela s rebellion is far bleaker. Everybody in the small town against me, firing me with their fiery fingers, pursued by those who claim they re nice, and I ll wear, before them all, the Crown of irritants that belong to the kept woman of a married adult male. ( Three Calamities 208 ) The agony Adela says she would digest in exchange for her freedom is the step of the intolerable abrasiveness of her female parent s authorization. When the grandma, Maria Josefa, first appears, her presence and words evoke a deformed image of the hereafter of her five granddaughters. She has dressed herself as a bride, I don t want to see these individual adult females hankering for matrimony, turning their Black Marias to dust ; and I want to travel to my hometown. Bernarda, I want a adult male to acquire married to and be happy with! ( Three Tragedies 175-6 ) Her message is excessively much for the girls to bear, they work together to return her to her locked room. Maria Josefa appears once more in the last minutes of the concluding act. No longer the bride, she carries a lamb whom she speaks to as if it were a kid, a grotesque lampoon of maternity. She sings a strange vocal, arousing the simple values of household, community, and freedom. Maria Josefa is the chorus in this drama, her visions of asepsis and decease are the most accurate images in the drama, she is the voice of truth. The development of act three follows the form established in Acts of the Apostless one and two: each scene begins serenely as the surface composure is undermined at a grim gait ( Anderson 126 ) , each act ends with a high degree of dramatic tenseness, the girls coercing their grandma into her room in act one, and in the 2nd all the family adult females # 8211 ; with the exclusion of Adela- connection in the violent persecution of a adult female who has killed her bastard kid. At the terminal of act three Adela and Martirio have a violent confrontation. They wake the family, and Bernarda hastes outside with a gun after El Romano. Fueled by green-eyed monster, Martirio tells Adela that he has been killed, in desperation she hangs herself. Bernarda reasserts her laterality which she hopes with restore a superficial composure in the house. Tears when you re entirely! Bernarda commands, We ll drown ourselves in a sea of mourning. She, the youngest girl of Bernarda Alba, died a virgin # 8230 ; Silence, silence, I said. Silence! ( Three Tragedies 211 ) The facts refering Lorca s decease are light. Shortly after finishing his manuscript of The House of Bernarda Alba, Lorca returned to Granada to be with his household. Lorca s brother-in-law, Manuel Montesinos, was the socialist city manager of Granada. ( Anderson 21 ) When the metropolis fell to the custodies of the fascists, he was executed. Lorca s household urged him to seek safety after he had been threatened by two armed work forces looking for reds. However, the fascist constabulary arrested him at his concealing topographic point, and held him in a stopgap prison. On the forenoon of August 18 or 19, 1936, Lorca was executed on a roadside ravine, and buried in an anon. mass gravesite. ( Stainton 455 ) Opportunities are that fewer people would hold heard Lorca s voice outside of Spain every bit early as they did, had it non been for his politically motivated decease. Lorca s roots are planted steadfastly in the Spanish yesteryear, his sensitiveness allowed him to conveying the past alive. For the Spaniards of his coevals he was the best debut to the 20th century, for us he is the debut to the ageless Spain. ( Duran 15 ) As his posthumous celebrity additions, his political martyrdom is no longer dominates his repute as a author. His dramas are now performed about worldwide, he is required reading in 100s of college classs. Possibly the best mark of his endowment and influence is inclusion as one of the top five Spanish authors of his clip. ( Honig 215 ) Bibliography Anderson, Reed. Federico Garcia Lorca.

Soda Ash Experiment free essay sample

To determine the efficiency of a titrimetric and potentiometric method while determining the carbonate in soda ash, both a t-test and f-test were performed. The t-test proved accuracy between methods and the f-test proved no difference in precision. Introduction Soda ash is a white anhydrous material that be found in either powder or granular form and it contains 99% sodium carbonate when shipped[i] (1). Soda ash serves a purpose in the manufacturing of many economically important products such as the manufacturing of glass, chemicals, paper, detergents and other products. Soda ash has been used dating all the way back to 3500 BC by the Egyptians. The Egyptians were able to utilize soda ash then in the production of glass and then as an ingredient in medicines and breads by the Romans (1). Today, the majority of the world’s soda ash comes from trona ore, which is mostly found in the Green River Basin, formerly known as the Gosiute Lake, located in southwest Wyoming. We will write a custom essay sample on Soda Ash Experiment or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The Green River basin is actually a prehistoric alkaline lakebed that supplies this vast amount of trona ore (1). With glass manufacturing being the largest application of soda ash, it erves very high importance in the production of containers, fiberglass insulation or flat glass for housing commercial building and automotive industries[ii] (2). Not only is the use of soda ash in glass manufacturing important, but it is also used to clean the air and soften water (2). With all of the new arising concerns with the environment with emissions in the atmosphere, the demand for soda ash has increased. This is so because soda ash can be used to remove sulfur dioxides and hydrochloric acid from stack gases present in the atmosphere (2). Since sodium carbonate has a strong base, it is commonly used to neutralize acidic effects so when a photographer were to develop film, he would use soda ash to stabilize the alkaline condition or a person who owns a pool would use it as an additive to chemically neutralize the water since chlorine makes the pool acidic (1). Soda ash has a high pH in concentrated solutions and can irritate the eyes, respiratory tract and skin. It should under no circumstance be ingested because soda ash can corrode the stomach lining (1). In the experiment that was conducted Na? CO? eacted with 0. 09356 M hydrochloric acid. Methods In the first part of this lab, roughly 1. 855g of sodium carbonate was weighed and put in the oven to dry at a temperature of 110 degrees Celsius for 2 hours. In part B, a 1 L solution of 0. 1 M HCl from 12. 0 M concentrated HCl was made to serve as the titrant for the lab. Do not discard the solution because it is used for both parts of the lab. Perform a rough titration of the dried standard Na? CO? with 0. 1M HCl to standardize the solution. The size of the sample weighed out should be enough to neutralize about 25 mL of 0. M HCl. On an analytically weighed balance weigh one sample of the dried primary standard sodium carbonate into a 125mL Erlenmeyer flask. Dilute the sample with 25mL of de-ionized water and then add roughly 4-5 drop of indicator Methyl Orange and titrate the solution to a point prior to the endpoint. Gently heat the sample solution on a hotplate in the fume hood until condensation appears around the neck of the flask to expel dissolved CO? from the sample. Cool the solution in an ice bath and finish titrating the roughly 0. 1 M HCl into the sample. A small amount of titrant is needed to reach the endpoint. Based off of the R value obtained from the rough titration, accurately weigh three more samples and repeat the titration. This data will be used to calculate the exact concentration of the HCl solution. In part C, titrating the unknown, accurately weigh about 0. 2g of dried unknown into a 125 mL Erlenmeyer flask and then add 25mL of de-ionized water and 4-5 drops of indicator (same as used in the rough). With the same procedure used in the standardization, titrate to just before the endpoint. Based off the R value from the rough titration of the unknown, accurately weigh 3 more samples and repeat the titration. In the second part of this lab, use a pH meter to titrate the unknown sodium carbonate. The instructor will help in setting up and calibrating a Vernier pH meter. The pH meter is calibrated with two buffer solutions with a pH of 4. 01 and the other with a pH of 10. 00. Based off of the calculated R value from part C accurately weigh two samples of the dried unknown sodium carbonate into two 150mL beakers. Add 25mL of de-ionized water to the first sample and place the electrode in the solution as well as a teflon stir bar and glass stirring rod and place on a stir plate. Record the initial volume of the HCl in the buret and carefully titrate with HCl until the pH is between 6. 0 and 6. 5. Be careful because the pH meter tends to lag. Once the target pH is achieved stop adding HCl and record the volume of the buret. Remove the sample beaker from the stir plate and put the electrode in a beaker filled with warm water. Warm the solution for a few minutes on a separate hot plate to expel dissolved CO?. Cool in an ice bath and return to the stir plate. Record pH, first data point, and continue to add increments of HCl until a pH of 2. 5 is achieved. Be sure not to add any de-ionized water after the first pH point is recorded. When completed there should be 30-40 data points. Repeat for the second sample. Results Table 1: Mass of the unknown Na?
