Concepts of Space in Art

Concepts of Space in Art In his book Space, Time and Architecture, Sigfried Giedion noted that through developments made during the Renaissance, the conception of space comes to fruition. This conception of space in art was expressed with the discovery of perspective. Through the use of perspective he says every element is related to the unique point of view of the individual. In linear perspective -etymologically clear seeing- objects are depicted upon a plane surface in conformity with the way they are seen, without reference to their absolute shapes and relations. The whole picture or design is calculated to be valid for one station and observation point only. To the fifteenth century the principle of perspective came as a complete revolution, involving an extreme and violent break with the medieval conception of space, and with the flat, floating arrangements, as its artistic expression. Sigfried Giedion, Space, Time and Architecture, Harvard University Press, Cambridge,  1967, first published 1941, pp. 30-31 During the Renaissance, fields of study particularly in the arts were closely intertwined with traditional models. In architecture, buildings were designed with reference to past examples. At around about the early nineteenth century, there came a shift in the conception of space that broke free of the rigidity associated with antiquity. Relativity in our conception of space came about through the development of cubism. Cubism introduced a new dynamic to visual representation. The framed view is coupled with different points of view of the same object, his brings in a factor of time. Joan Ockman professor and the director of the Temple Hoyne Buell Center for the  Study of American Architecture at Columbia University. Here will be cited her essay The  Way Beyond Art published in Autonomy and Ideology, ed.Somol, R.E., the Monacelli Press,  New York, 1997, pp.83-120 matter ceased to be understood as opaque mass. The viewer now envisaged different aspects of space simultaneously, inside and outside, convex and concave at once. Matter was decomposed into simple surfaces and lines (as in Mondrian) or became transparent and interpenetrating (as in Lissitsky). With these developments, space came to be understood as a crossing of movements and energies. The change in the conception of space is said to be the demolition of pictorial space by Cubist techniques and substitution of a relative point of view for an absolute one Along with Ockman, Sigfried also wrote about a new conception of space from the traditional. He claims that classical conception of space is related to the notion of perspective and this notion was the primary element in painting since the Renaissance up until the 20th Century. For Giedion, the new method of visual representation after the formation of cubist techniques coincides with a shift in the conception of space and develops form giving principles of the new space conception After Cubism, space conception changes from the static perception of the Renaissance. Giedion claims that the classic conceptions of space and volumes are limited and one sided. For Giedion, the possibilities of this new space conception is like Cubism with its many perspectives that extract the essence of the subject, give it an infinite potential for relations within it. Giedion claims that the dawn of cubism is an anonymous principle just like the discovery of perspective. That cubism is the expression of a collective and almost unconscious attitude and for him, this expression is also closely related to scientific advancements of that period. As Giedion says. Cubism breaks with Renaissance perspective. It views objects relatively: that is, from several points of view, no one of which has exclusive authority. And in so dissecting objects it sees them simultaneously from all sides from above and below, from inside and outside. It goes around and into its objects. Thus to the three dimensions of the Renaissance which have held good as constituent facts throughout so many centuries, there is added a fourth one time: In stage design, the stage itself can become a medium for the exploration and the experimentation of different concepts in vision and space conception. The stage is the manifestation of the relationship between performers and audience. In her book, Theatres, Gaelle Breton makes reference to ancient theatres. She says that the Greek theatres of antiquity sought to create a unity between the stage and audience areas and combined them under an open air space. This principle she states becomes the model for Elizabethan theatres which she identifies with the Shakespeare Globe Theatre. Breton states that during the Renaissance, theatre design undergoes an increasing separation from the outside world, and within creates an ever increasing divide between stage and spectator who sit in a fix position for an optimum static perspective. This resembles the painting of the time. The way theatres were designed during the Renaissance was challenged by Richard Wagner. Together with architect Otto Brukwald, they collaborated to design theatre which sought a reversal in the separation of and stage. The theatre of the Renaissance was concerned with the audience with the perspective of the audience. No balconies and a darkened auditorium focused the audiences attention to the stage. Theatre no longer sought to create the illusion of reality but sought to express the essence of a play. Breton also claims that the necessity for creating the illusion of reality became less relevant with the advent of cinema and the innovation of cubism which shattered the traditional perception space and style of spatial representation Antonin Artaud (1862-1928) was a famous stage director and the author of Theatre and its Double. He describes the architectural space that he seeks for his productions as a single, universal locale without any partitions of any kind His proposal was to abandon the architecture of his time and set about producing production that could be held in a barn or a hanger for performance. The notion of flexible space such as this can also be seen in the architecture of Ludwig Mies van der Rohe around this time. The concept is for a performance space as a total space which can be redesigned and reorganized for different productions. The sculptor and painter Oscar Schlemmer, conducts experiments for stage space at the Bauhaus. Roselee Goldberg state that the work at the Bauhaus was to achieve a synthesis of art and technology in pure form The studies conducted included the problems of performance space such as the opposition of visual place and spatial depth Schlemmers experiments demonstrated a new conception of space on stage. In the 1920s, the discussion of space centred on the notion of felt volume Schlemmer explained that out of the plane geometry, out of the pursuit of the straight line, the diagonal, the circle and the curve, a stereometry of space evolves, by the moving vertical line of the dancing figure. The relationship of the geometry of the plane to the stereometry of the space could be felt if one were to imagine a space filled with a soft pliable substance in which the figures of the sequence of the dancers movements were to harden as a negative form Up until the twentieth century, the criteria for stage design was a framed view and theatres based on the relation of the proscenium. In the early twentieth century, revolutionary stage designers such as Edward Gordon Craig challenged this two dimensional approach to stage design with three dimensional concepts and experiments. For his first production, Craig had to design his own stage as the only available space was the Hampstead Conservatoire. This concert hall was 44ft wide with a series of stepped platforms at one end to house the orchestra. The comprises made by Craig became a characteristic of his work. The ceiling height was level throughout and Craig incorporated Herkomers technique of over head lighting and sky effects. A low proscenium was constructed to facilitate frames and a bridge above the stage for the lighting man. To facilitate a cast and chorus of 75, the full width of the stage was utilized. This created a strikingly panoramic effect. In later production in Coronet and Great Queen Street theatres, Craig lowered the proscenium by as much as 12ft to create the impression of great width. He also found that creating stepped platforms allowed for three dimensional groupings and movement. Craig wanted the spectators to have the same perspective of the plays so no side galleries, or boxes were used, instead a single level seating was used. Another characteristic of Craigs productions which challenged the viewers imagination were, although the sets were openly theatrical, with everything from imitation vine leaves to crude papier-mà ¢chà © boars head, on the other hand there was a deliberate avoidance of realistic detail and simple effects of colour were used, leaving the imagination free and achieving a suggestiveness that one viewer had commented reminded him of the delicate friezes of Pompeii. For these surfaces, Craig explains they stand on the stage just as they are, they do not imitate nature, nor are they painted with realistic or decorative designs Craig studied the theatrical work as it was in ancient Greece, Rome, from the Renaissance to the Elizabethan. He noted that Once upon a time, stage scenery was architecture. A little later it became imitation architecture, still later it became imitation artificial architecture. The two elements which became central to Craigs concept of a new theater were lighting and movement. The two elements which became central to Craigs concept of a new theater were lighting and movement. The great days of painted scenery belonged to the era of dim lighting from gas-few footlights or candles, which flattened the performer so that he an the picture became one. The day the first spotlight was on the side of the proscenium, everything changed. The actor now stood out, was substantial, and a contradiction suddenly appeared between roundness and the two dimensional trompe loeil behind his back. The great innovators in the art of scenic design, Adolphe Appia and Gordon Craig, knew this before the First World War. Peter Brook, Threads of Time, Methuen Publishing Limited, London, 1999, p.48 In 1923, Fredrick Kiesler presented his concept for the Endless Theatre. The theme of this space was the structure did not have any frame, but could still maintain its form. In the 1920s architecture had a strong tendency to interpret space from a functional point of view. Buildings where traditionally of a rectangular shape, however there were no corners in Kieslers endless concept. This implies a meaning of time and space simultaneously which one can interpret as without and en, or in another sense an eternity of time. While this theatre expressed Kieslers concept of space, it was in 1958 when he presented the Endless house that his concept had manifested itself into a space that responded to human sensibilities as well as a functional space acting as a home. An installation architecture piece by Bernard Tschumi called the Glass Video Gallery was constructed in the Netherlands. It is a glass structure which contains 6 banks of video monitors. The projects intention was to challenge our preconceived ideas on the act of viewing. The monitors act as an unstable faà §ade, unlimited space is suggested through mirror reflections. The reflective surfaces which can be interpreted as a modern day equivalent to Edward Gordon Craigs walls. The immateriality presents an ambiguous surface. The architect presented a challenge to the permanence of buildings. The multiplying layers act to dissolve the surface of the glass. Lighting at night acts to transform the space. For Tschumià ¢Ã¢â€š ¬Ã‚ ¦ The endless reflections of the video screens over the vertical and horizontal glass surfaces reverse all expectations of what is architecture and what is event, of what is wall and what is electronic image, of what defines and what activates. Tschumi also claims that his glass box challenges the ideas of television viewing and about privacy. The transparency of the glass walls acts as an opposition to an enclosed private space it also acts as an extension to the street. Within the structure, a person watches and is watched at the same time.

Technology and Its Impacts on Society

Introduction:Changes have been described as essential functions to human life in the society. Changes are inevitable as man and the society continue to exist. Technology and inventions are spearheaded by man and interact with the society to bring about the necessary social changes. Each year, various technological inventions that are embraced which leads to their steadily increasing impacts on the social aspects within the society.Technology advancement therefore has become essential in shaping the society as it has traversed virtually all aspects of human life. Technological innovations are responsible for the new social themes being experienced within the modern society. It is therefore important to note that new technologies will impact on the choices we make, how we lead our lives, and on how we interact with others. The internet and the mass media in particular have led to far reaching implications especially in matters to do with inter-personal communication and the general soc iological aspect within the society.This paper shall focus on how technological advances have impacted on the society and interpersonal communication.The Internet and Mass media:In the recent past, the use of the internet has drastically increased. Studies have shown that in the case of the United States, which is the world’s leading nation in internet use, the internet use had risen from 66% to 73% in 2006[1]. In the survey, it was revealed that about 70% of adult Americans were internet users. Though the United States is the world’s leader in internet use, other countries around the world are quickly adapting the trend and the internet use has gained considerably. It is no wonder that e-communications are being incorporated as crucial in effecting behavioural and social changes within the society[2].Internet has disregarded geographical distances and separations in this new world order, as borders no longer have great impact on limiting people’s activities. Pe ople are encouraged to participate and contribute on different aspects which have drawn different experiences and pooled resources together. Actions and reactions have become instantaneous in cyberspace and this has made internet to be more gratifying and attractive. The resultant effect is that internet has impacted our society in almost all areas of human endeavours.The problem is that the impact has been both positive and negative and as such, caution has been advocated as a means in which citizens should approach the internet[3]. In matters of communication, technological advancement has been experienced in immeasurable quantities. There have been tremendous developments in the mass media industry including TV, radio, newspapers, telephone and wireless gadgets that have facilitated the communication between individuals. Advance research has led to development of space technologies and satellites which are used for communication thereby adding to the sophistication of the industr y. The geographical distance between individuals is no longer an issue as the technology has come to fill the gap[4].The Impacts of the internet and mass media on the society:It is a matter of fact that easy access to the internet, which includes the availability of personal computers with rather cheap prices, introduction of reliable internet services and establishment of internet cafes has changed the nature of people’s connection to each other in their social field. Physical proximity is no longer an essential in communicating to one another face to face. Technology has made it easier for rapid connections across long distances and people are now in a position to write electronic mails that are transmitted virtually immediately throughout the globe[5].Eskicumali argues that there are various aspects of the lives of individuals, especially the young people which have been altered by the internet. The basic nature of their relationships with one another has been greatly infl uenced by the internet. This is due to the reason that there has been a global diffusion of information and communication technologies that has expanded the domain of ‘absent presence’ which in turn has resulted to an erosion of face to face community centred relationships[6]. The internet has created new type of social relations and virtual communities that has not been formed ever since.These virtual communities are social network of individuals who interact through specific media, and potentially crossing geographical and political boundaries, so as to pursue mutual goals and interests. The internet has also impacted the social system in form of communication[7]. There is diversity in the internet-mediated communication which is displayed in different sectors such as politics, art, family, and mass media among others. It has become the bearer of different kinds of communication. This is due to several features of internet’s technical and textual structure whic h has promised to have a crucial impact on communication[8].Technology is said to be providing a link between individuals located at different parts of the world but at the same time, it can be argued that the same technology is creating enclaves for these same individuals. The use of technology can lead to situations whereby individuals find themselves glued to the use of modern technology and having little or no time to spend with others. The internet in particular has led to the development of social network sites which alienates individuals from socializing with their close friends and relatives as they are glued to chat-rooms with ‘distant’ friends[9].Interpersonal Communication:Technology can be used to either enhance or inhibit any given aspect of human life. It is however the interpersonal communication that would feel the effects of technology first. Historically, the modes of communication have been changing over time in line with the evolution of the society. People dispersed in various parts of the world and verbal communication was altered to letter writing so as ensure that there was communication. Individuals came with inventions on how to carry out the conversation as well as written communication amongst two members that were geographically apart. The telephone came up and most individuals thought that now the other forms of communication would become obsolete[10].With family and friends relocating to different parts of the globe, the telephone technology came in as a blessing in ensuring that family and friends could still stay in touch irrespective of the geographical barriers. The advent of computers has simplified communication even further by bringing to the forefront the concept of instant messaging between individuals who are millions of miles apart[11].   It should be noted that any advancement of technology in communication does not replace the existing one as each is capable of surviving by its own rules providing vari ous options to the individuals.The impact of technology on the interpersonal communication has also come with its demerits. Individuals have tended to side with the use of technology in communicating hence loosing on the ‘personal touch’ which is very essential in the communication process. Technology has provided room for individuals to loose the art of effective communication which can only be realized through face to face communication. This is accomplished by body language, eye contact, and any other observable feature when communicating. Social cowards are able to hide behind technology to air their disagreements as the technology offers some sort of false sense of security and ambiguity[12].Conclusion:The advancement in technology is often meant to better the lives of human beings. Nevertheless, the impacts of technological advancement come in two folds — advantages and disadvantages. What is important though is to look at the differences between the advant ages and the disadvantages in order to evaluate the net effect of the technology on human society. The advancement that has been made in the communication sector is great and has had far reaching impacts on the society in general. The internet in particular has led to critical impacts in the sharing of information as well as reducing the world into a global village where communication becomes instantaneous irrespective of the geographical distance between the communicating parties.With advancement in technology, interpersonal communication has been greatly affected since individuals have turned to the ‘faceless’ technology to communicate. This has had its merits and demerits. Though technology has eased the communication, the effectiveness of the communication has greatly been hampered. Though technology has two sides just like any other issue that may come up in the society, its merits especially in the communication sector are greater than the associated disadvantages . Technology is here to stay and it is bound to influence virtually all aspects of our lives. The internet for instance is ubiquitous in everyday life and its impacts are far from over given that technology is usually cumulative.Bibliography:Bergschneider, Veronica.

Supremacist Ideologies in Heart of Darkness nbsp; Joseph Conrads Heart of Darkness colludes with the ethnocentric attitude of Europeans towards the native people of Africa. At the turn of the century, European imperialism was viewed as a crusade worthy of this century of progress by King Leopold of Belgium. Although Conrad was critical of imperialism, his novella reveals to the reader an undeniable Victorian provenance.

In this encounter, the Africans are seen as a howling mob. Marlow does admit a remote kinship with them, but he explains that he was prevented from going ashore for a howl and a dance because of his dedication to efficiency and his redeeming work ethic. Marlow describes the native who works as a fireman on board the steamer as an improved specimen who had been given the gift of improving knowledge by the Europeans. Yet the narrator is condescending towards his intrepidity in working the boiler and calls him a fool-nigger for having deserted his post during the attack. The ideologies of the British gentleman are consistently privileged over any attempt to understand the natives. nbsp; In almost all of these encounters, black Africans are denied speech.
