Аркадия: Пьеса Тома Стоппарда о прошлом и настоящем.

1993 play by Tom Stoppard

Arcadia is a 1993 stage play written by English playwright Tom Stoppard, which explores the relationship between past and present, order and disorder, certainty and uncertainty. It has been praised by many critics as the finest play from "one of the most significant contemporary playwrights" in the English language. In 2006, the Royal Institution of Great Britain named it one of the best science related works ever written.

In 1809, Thomasina Coverly, the daughter of the house, is a precocious teenager with ideas about mathematics, nature, and physics well ahead of her time. She studies with her tutor Septimus Hodge, a friend of Lord Byron (an unseen guest in the house). In the present, writer Hannah Jarvis and literature professor Bernard Nightingale converge on the house: she is investigating a hermit who once lived on the grounds; he is researching a mysterious chapter in the life of Byron. As their studies unfold – with the help of Valentine Coverly, a post graduate student in mathematical biology – the truth about what happened in Thomasina's time is gradually revealed.

The play opens on 10 April 1809, in a garden front room of the house. Septimus Hodge is trying to distract 13 year old Thomasina from her curiosity about "carnal embrace" by challenging her to prove Fermat's Last Theorem; he also wants to focus on reading the poem "The Couch of Eros" by Ezra Chater, who with his wife is a guest at the house. Thomasina starts asking why jam mixed in rice pudding can never be unstirred, which leads her to the topic of determinism and to a beginning theory about chaotic shapes in nature. This is interrupted by Chater himself, who is angry that his wife was caught in the aforementioned "carnal embrace" with Septimus; he has come to demand a duel. Septimus tries to defuse the situation by heaping praise on Chater's "The Couch of Eros". The tactic works, because Chater does not know it was Septimus who had savaged an earlier work of his, "The Maid of Turkey". Landscape architect Richard Noakes enters, shortly accompanied by Captain Brice and Lady Croom; the three discuss proposed modifications to the Arcadian style gardens, while Thomasina sketches an imaginary hermit on Noakes's technical drawing of the garden.

The present day. Hannah Jarvis is researching the house, the garden, and specifically the hermit, for a study of hermits and the Romantic imagination. Bernard Nightingale enters with Chloe Coverly; she conceals the professor's identity from Hannah, as Nightingale had given Hannah's last book a poor review. Chloe's brother, Valentine, is gathering data on the population biology of the grouse in the surrounding grounds, using the house's "game books". When Chloe accidentally reveals Bernard's identity, Hannah reacts angrily; but she agrees to share her research material. This enables him to propose the theory that one of the 1809 inhabitants, Ezra Chater, was killed by Lord Byron in a duel. Bernard notes that records of Chater the poet disappeared after 1809, and the only other Chater of record is a botanist.

The 19th century. Septimus is tutoring Thomasina, this time in translating Latin. Again their focus diverts, this time to the destruction of the Alexandrian Library, which upsets Thomasina. She mourns the loss of the knowledge stored there, and Septimus responds that all that was lost will eventually turn up again. They are interrupted by Chater, who succeeds in challenging Septimus to a duel, having learned (from Lord Byron off stage) that Septimus wrote the damning review of his work.

The present. Hannah rediscovers Thomasina's primer containing her ideas on iteration and chaos theory; this recalls Septimus' assertion that what was lost is eventually rediscovered. Valentine reacts with interest to the notes, as his own research centres on similar concepts.

Bernard gives Hannah, Valentine, and Chloe a preview of his lecture theorising that Lord Byron shot and killed Chater in a duel. When Hannah and Valentine challenge his logic, Bernard launches into a diatribe about the irrelevance of science, then departs for his lecture (and a promotional media appearance) in London. Hannah begins to suspect that the hermit of Sidley Park – who was reportedly obsessed with algebraic computations about the heat death of the universe, the theory suggested in Thomasina's diagram – could have been Septimus.

Returning to 1809, we learn that the duel never occurred. Instead, the Chater couple left for the West Indies with Captain Brice. Chater served as the expedition's botanist and his wife Charity was the captain's secret paramour. Lord Byron has also left the country. Septimus has gone rabbit hunting for Thomasina, who favours rabbit pie; he returns to find Lady Croom searching for him. She has found two letters, a love letter addressed to her, and another to Thomasina about rice pudding, both written by Septimus in case he died in a duel. She invites Septimus to an amorous rendezvous.

Both 1812 and the present, the actions running concurrently. Some present day characters are in fancy dress for a party, so that both casts appear similarly attired. After reading a newspaper report on the Byron murder theory, Chloe talks about determinism with Valentine, echoing the discussion between Septimus and Thomasina. Chloe, however, believes that sex is the force that disrupts the universe's ordered plan. Valentine, using his computer to extrapolate Thomasina's ideas, relates them to the later developed concept of entropy. He wonders whether Thomasina or Septimus was the genius behind the theories. Hannah and Valentine mention that Thomasina died in a fire on the eve of her seventeenth birthday. Meanwhile, Thomasina asks Septimus to teach her to dance, to prepare for her forthcoming 17th birthday party. Lady Croom enters, complaining to Noakes about the noise of his steam engine; Thomasina notes that the machine obeys the laws of entropy (which have not yet been formalized), which describe the universe as winding down. In the present, Bernard arrives and is met by Hannah, who has found a letter detailing the facts of Chater's death – this discovery totally discredits Bernard's theory and vindicates Lord Byron's reputation. While Septimus awaits appropriate music for Thomasina's dance lesson, he examines the sketch she made to illustrate the irreversibility of heat; his action mirrors that of Hannah and Valentine, who pondered the same diagram. Bernard is caught in a compromising position with Chloe, and is asked to depart. Eventually a waltz starts, and Septimus dances with Thomasina, revealing that their relationship is increasingly complicated by hints of romance. Gus (Valentine and Chloe's younger brother, who has been silent for the entire play) hands another of Thomasina's drawings to a surprised Hannah. It depicts Septimus and the tortoise, confirming her suspicion that the hermit, who had a tortoise called Plautus, was Septimus. After Thomasina's tragic death, he apparently became a hermit. Accepting her challenge to the laws of the universe as propounded by Newton, he worked for the rest of his life to apply "honest English algebra" to the question of the universe's future.

Thomasina Coverly: The 13 year old (later 16 year old) daughter of Lord and Lady Croom, Thomasina is a precocious genius. She comes to understand chaos theory and the second law of thermodynamics, before either is established in the mathematical and scientific communities. Stoppard "apparently based" the character on Lord Byron's daughter Ada Lovelace (Augusta Ada King, Countess of Lovelace). She was an English mathematician who conceptualised how Charles Babbage's Analytical engine could be used, foreseeing the binary computer. Septimus Hodge: Thomasina's tutor, and the academic colleague and friend of Lord Byron (an unseen but important character). While teaching Thomasina, he works on his own research and has affairs with the older women of the house. When Thomasina is older, he falls in love with her; after her death, he becomes the "hermit of Sidley Park", working on her theories until his own death. Jellaby: The Crooms' butler. His chief functions are to spread gossip and to deliver letters. Ezra Chater: An unsuccessful poetaster staying at Sidley Park. His wife's romantic affairs lead him to challenge Septimus to a duel. Later, it is revealed that he is the amateur botanist "Mr. Chater," who dies of a monkey bite in Martinique, where he has travelled with his wife and Captain Brice. Charity Chater: Ezra Chater's wife. Though she, like Byron, never appears onstage, she plays a vital role. She sleeps with Septimus, and her repeatedly cuckolded husband challenges him to a duel. She sleeps with Lord Byron and gets him, Captain Brice, her husband and herself expelled from Sidley Park. Richard Noakes: Lady Croom's gardener. Throughout the play, he is working to transform Sidley Park's classical, Arcadia like landscape into the popular Gothic style – which Lady Croom begrudgingly accepts. He is key in exposing Septimus's and Mrs. Chater's affair. Lady Croom: Thomasina's mother. She rules the Coverly estate with an iron fist, but flirts with Septimus and other gentlemen throughout the play. A second Lady Croom, the mother of Valentine, Chloe, and Gus in the modern half of the play, never appears on stage. Captain Brice: The brother of Lady Croom (of 1809). He is a sea captain who falls in love with Mrs. Chater. He takes her and her husband to the West Indies at the end of the play. After Mr. Chater's death, Captain Brice marries the widowed Charity Chater. Augustus Coverly: Thomasina's trouble making younger brother. He appears in only a few brief scenes. (Gus and Augustus are played by the same actor.)

Hannah Jarvis: The author of a best seller on Byron's mistress Lady Caroline Lamb. Hannah is researching the elusive hermit of Sidley Park, said to have lived there in the early 19th century. Hannah collaborates (warily) with Bernard and also with Valentine, though she rejects the romantic advances of both. Chloe Coverly: The 18 year old daughter of the modern Lady Croom. While her mind is not as rigorous as Thomasina's, Chloe likes to propose wild ideas. She argues that the Newtonian universe has been destabilized by sex and the problems it causes. She tries to set up Hannah with Bernard, but ends up sleeping with him herself. Bernard Nightingale: A don at a modern university in Sussex, England. Bernard comes to Sidley Park hoping to work with Hannah on his theory about Lord Byron staying at the estate. Instead of seeking further evidence, he announces on TV his theory that Lord Byron killed Ezra Chater in a duel. At the end of the play, Hannah proves him wrong, much to his chagrin. Valentine Coverly: Chloe's older brother. A graduate student of mathematics, he pores over several old documents and comes to acknowledge Thomasina's genius. Gus Coverly: Valentine and Chloe's younger brother, who has been mute since the age of five. Gus helps to pass several important props from past to present, and helps connect key moments in the play. (Gus and Augustus are played by the same actor.)

Arcadia is, on the surface, somewhere between a tragedy and a comedy. It involves some elements of classical tragedy – "noble" characters and the audience's foreknowledge of Thomasina's death – but the predominant element is comedy, in the way that the characters interact with each other and in their witty, epigrammatic dialogue.
