Sare sozialak

Sare sozial guztiak berdinak direla uste al duzu? Bada, horrela pentsatzen baduzu oker zabiltza. Izan ere, denek funtzean helburu berdina izan arren, hots, komunikatzea, desberdintasun ugari dituzte haien artean.

Facebook, Tuenti eta Twitterbezalako sare sozialak, antzeko sare sozialak dira eta guztiek komunikatzeko helburua dute. Bestalde, beraien artean ezberdintasunak bilatzen hasiko baginateke, pribatutasunean aurkituko genituzke lehenego desberdintasunak.baginateke, pribatutasunean aurkituko genituzke lehenego desberdintasunak.

Bestalde, espainiar mailan, Tuenti da sare sozialik indartsuena, baina mundu mailan, Facebook da jaun eta jabe. Izan ere, Tuentik 2 milioi erabiltzaile ditu eta Facebook-ek 350 milioi. Alde nabarmen hau Tuenti sare itxia delako ematen da. Izan ere, Tuentin kontu bat irekitzeko, aurretiaz Tuentiko erabiltzaile den norbaitek gonbidatu behar zaitu.

Facebook-a aldiz, sare irekia da eta edonor sar daiteke bertan inolako gonbidapenik jaso gabe.

Facebook, Mark Zuckerbergek sorturiko webgune sozial bat da. Harvard Unibertsitateko ikasleentzat sortua izan zen hasiera batean, baina orain mundu guztiari irekia dagoen sare bat da. Erabiltzaile bakoitzak bertako sare ezberdinetan ibili daiteke, bere ikasketen araberako, bere bizitokiaren araberako edo bere lanaren araberakoa izan daitekeelarik, beste aukeren artean.

Facebook oso ezaguna bilakatu zen, negozio modelo berri bat zelako, baina iragarkietatik lortzen zituen mozkinak oso onak ez direnez, negozio modelo horrek ez du jaso espero genuen arrakasta.

Tuenti gazteei zuzendua eta web 2.0an oinarritutako lagun-sare bat da. Bertan, tuenti-orri pribatua eskura daiteke izena eman ondoren. Behin tuenti-orria lortuta, mugarik gabe argazkiak igo, norberaren blogean testuak idatzi eta besteen tuenti-orrietan edota argazkietan iruzkinak jar daitezke besteak beste.

Tuenti-orriaren pribatutasun-maila aukera daiteke: lagunek bakarrik ikusi ahal izatea, lagunek eta haien lagunek ikusi ahal izatea, edota pertsona guztiek ikusi ahal izatea.

Hemen, jendea oso erraz aurki daiteke: izen-abizenen bidez, lana edota doazen eskolaren izena bilatuz, bizilekua bilatuz, martxara irteten diren tokien bidez, lagunen lagunen bidez, e.a.

Beste alde batetik, Tuenti 24 urtetik beherakoei zuzendua dago eta Facebook-ak aldiz, ez du bataz besteko adin kopuru zehatzik.

Twitterreko erabiltzaileak ordea, 25 eta 50 urte bitartekoak dira.

Twitter sare sozial eta microblogging zerbitzua da, bere erabiltzaileei testu soileko mezuak bidaltzea ahalbidetzen diena, 140 karaktereko gehienezko luzerarekin. Eguneraketa hauek erabiltzailearen profilean erakusten dira, eta jasotzeko aukera hautatu duten beste erabiltzaileei ere bidaltzen zaie. Jatorrizko erabiltzaileak mezu hauek berak aukeratutako lagunei soilik bidaltzeko aukeratu dezake, edo erabiltzaile guztien eskura jarri ahal daitezke.

Facebook-ek ez du karaktere mugarik ostera.

Twitterrek komunikazioa, diseinua eta teknologiarekin lotuta dauden ikasketekin zerikusia du eta Facebook ostera, edozein pertsonari zuzendua dago.

Laburbilduz, Facebook, Tuenti eta Twitter sare sozialak ezberdintasun ugari izan arren beraien formatuetan, azken finean xede berbera partekatzen dutela ikus dezakegu, hots, pertsonek elkar komunikatzeko aukera eskaintzen digute.

Multikulturalitatea eta kulturen arteko elkarrizketa

Kulturen Talka, Hungtingtonek eginiko artikulu bat da, bertan estatuen arteko gatazken zergaitia kultur desberdintasunean dagoela argidiatzen du eta iraganean estau politikoak baino, kultur estatuak egongo direla dio, beti beste kultur estauten aurka borrokan.

Hautatu dudan ikasgaia Multikulturalitatea da. Bertan, konpetentzia espesifikoetan esaten den moduan, gaur egungo gizarteko aniztasuna ulertu eta onartzeko helburua dugu. Hori gauzatu ahal izateko klasean ematen den informazioaz gain, testuak aztertu, talde lanak eta iruzkinak egiten ditugu.

Ideia horiek lan batean pilatu genituen eta atera genuen ondorio naguzia ematen digutenaz arago joan behar dugula da, izan ere, hasieran Hungtingtonek esaten zuenarekin erabat adoz geunden, baina kritikak aztertu ostean ikusi dugu zelan esaten zuena ez zen guztiz egiazkoa.

Ikasgai honetan ikasten den beste gauza garrantzitsu bat besteekiko eritsia eraikitzerakoan iturri eta ikuspuntu desberdinak kontuan hartu behar direla da. Hau Kulturen Talka deituriko artikulua irakurriz frogatu genuen.

Kulturen Talka, Hungtingtonek eginiko artikulu bat da, bertan estatuen arteko gatazken zergaitia kultur desberdintasunean dagoela argidiatzen du eta iraganean estau politikoak baino, kultur estatuak egongo direla dio, beti beste kultur estauten aurka borrokan.

Artikulu honek kritika anitz jaso zituen, eta gure lana kritika horiek aztertzea izan da. Kritikari sustuenen artean Fred Hallyday eta Edward Said ditugu, azkeneko honen esanetan, Hungtintonek komeni zaizkion “egiak” hartu ditu eta horiekin bere interesak defendatzen dituela dio. Fred Hallyda esaterako, kultur arteko gatazkaren aurka dago eta munduko tirabiren iraunkortasuna bi alderdietatik egiten den propagandaren bitartez bermatzen da, izan ere, gatazken atzetik asmo eskutuak daude, ala nola armagintza enpresek dituztenak.

Best known works of the great masters of the Cinquecento

The Last Supper from Leonardo da Vinci.

The Last Supper measures 450 × 870 centimeters (15 feet × 29 ft) and covers an end wall of the dining hall at the monastery of Santa Maria delle Grazie in Milan, Italy. The theme was a traditional one for refectories, although the room was not a refectory at the time that Leonardo painted it. The main church building had only recently been completed (in 1498), but was remodeled by Bramante, hired by Ludovico Sforza to build a Sforza family mausoleum. The painting was commissioned by Sforza to be the centerpiece of the mausoleum. The lunettes above the main painting, formed by the triple arched ceiling of the refectory, are painted with Sforza coats-of-arms. The opposite wall of the refectory is covered by the Crucifixion fresco by Giovanni Donato da Montorfano, to which Leonardo added figures of the Sforza family in tempera. (These figures have deteriorated in much the same way as has The Last Supper.) Leonardo began work on The Last Supper in 1495 and completed it in 1498—he did not work on the painting continuously. This beginning date is not certain, as “the archives of the convent have been destroyed and our meagre documents date from 1497 when the painting was nearly finished.”

The Last Supper specifically portrays the reaction given by each apostle when Jesus said one of them would betray him. All twelve apostles have different reactions to the news, with various degrees of anger and shock. The apostles are identified from a manuscript (The Notebooks of Leonardo Da Vinci p. 232) with their names found in the 19th century. (Before this, only Judas, Peter, John and Jesus were positively identified.) From left to right, according to the apostles heads:

  • Bartholomew, James, son of Alphaeus and Andrew form a group of three, all are surprised.
  • Judas Iscariot, Peter and John form another group of three. Judas is wearing green and blue and is in shadow, looking rather withdrawn and taken aback by the sudden revelation of his plan. He is clutching a small bag, perhaps signifying the silver given to him as payment to betray Jesus, or perhaps a reference to his role within the 12 disciples as treasurer.[5] He is also tipping over the salt shaker. This may be related to the near-Eastern expression to “betray the salt” meaning to betray one’s Master. He is the only person to have his elbow on the table and his head is also horizontally the lowest of anyone in the painting. Peter looks angry and is holding a knife pointed away from Christ, perhaps foreshadowing his violent reaction in Gethsemane during Jesus’ arrest. The youngest apostle, John, appears to swoon.
  • Jesus.
  • Apostle Thomas, James the Greater and Philip are the next group of three. Thomas is clearly upset; James the Greater looks stunned, with his arms in the air. Meanwhile, Philip appears to be requesting some explanation.
  • Matthew, Jude Thaddeus and Simon the Zealot are the final group of three. Both Jude Thaddeus and Matthew are turned toward Simon, perhaps to find out if he has any answer to their initial questions.

In common with other depictions of The Last Supper from this period, Leonardo seats the diners on one side of the table, so that none of them have their backs to the viewer. Most previous depictions excluded Judas by placing him alone on the opposite side of the table from the other eleven disciples and Jesus or placing halos around all the disciples except Judas. Leonardo instead has Judas lean back into shadow. Jesus is predicting that his betrayer will take the bread at the same time he does to Saints Thomas and James to his left, who react in horror as Jesus points with his left hand to a piece of bread before them. Distracted by the conversation between John and Peter, Judas reaches for a different piece of bread not noticing Jesus too stretching out with his right hand towards it. (Matthew 26: 23). The angles and lighting draw attention to Jesus, whose head is located at the vanishing point for all perspective lines.

The painting contains several references to the number 3, which represents the Christian belief in the Holy Trinity. The Apostles are seated in groupings of three; there are three windows behind Jesus; and the shape of Jesus’ figure resembles a triangle. There may have been other references that have since been lost as the painting deteriorated.

The School of Athens from Raphael

The School of Athens, or Scuola di Atene in Italian, is one of the most famous frescoes by the Italian Renaissance artist Raphael. It was painted between 1510 and 1511 as a part of Raphael’s commission to decorate with frescoes the rooms now known as the Stanze di Raffaello, in the Apostolic Palace in the Vatican. The Stanza della Segnatura was the first of the rooms to be decorated, and The School of Athens the second painting to be finished there, after La Disputa, on the opposite wall. The picture has long been seen as “Raphael’s masterpiece and the perfect embodiment of the classical spirit of the High Renaissance.”

The “School of Athens” is one of a group of four main frescoes on the walls of the Stanza (those on either side centrally interrupted by windows) that depict distinct branches of knowledge. Each theme is identified above by a separate tondo containing a majestic female figure seated in the clouds, with putti bearing the phrases: “Seek Knowledge of Causes”, “Divine Inspiration”, “Knowledge of Things Divine” (Disputa), “To Each What Is Due”. Accordingly, the figures on the walls below exemplify Philosophy, Poetry (including Music), Theology, and Law. The traditional title is not Raphael’s, and the subject of the “School” is actually “Philosophy”, or at least ancient Greek philosophy, and its overhead tondo-label, “Causarum Cognitio” tells us what kind, as it appears to echo Aristotle’s emphasis on wisdom as knowing why, hence knowing the causes, in Metaphysics Book I and Physics Book II. Indeed, Aristotle appears to be the central figure in the scene below. However all the philosophers depicted sought to understand through knowledge of first causes. Many lived before Plato and Aristotle, and hardly a third were Athenians. The architecture contains Roman elements, but the general semi-circular setting having Plato and Aristotle at its centre might be alluding to Pythagoras’ circumpunct.

Commentators have suggested that nearly every great Greek philosopher can be found within the painting, but determining which are depicted is difficult, since Raphael made no designations outside possible likenesses, and no contemporary documents explain the painting. Compounding the problem, Raphael had to invent a system of iconography to allude to various figures for whom there were no traditional visual types. For example, while the Socrates figure is immediately recognizable from Classical busts, the alleged Epicurus is far removed from the standard type for that philosopher. Aside from the identities of the figures depicted, many aspects of the fresco have been variously interpreted, but few such interpretations are generally accepted among scholars. The popular idea that the rhetorical gestures of Plato and Aristotle are kinds of pointing (to the heavens, and down to earth) is a likely reading. However Plato’s Timaeus – which is the book Raphael places in his hand – was a sophisticated treatment of space, time and change, including the Earth, which guided mathematical sciences for over a millennium. Aristotle, with his four elements theory, held that all change on Earth was owing to the motions of the heavens. In the painting Aristotle carries his Ethics, which he denied could be reduced to a mathematical science. It is not established how much the young Raphael knew of ancient philosophy, what guidance he might have had from people such as Bramante, or whether a detailed program was dictated by his sponsor, Pope Julius II. Nevertheless the fresco was even recently interpreted as an exhortation to philosophy and, in a deeper way, as a visual representation of the role of Love in elevating people toward upper knowledge, largely in debt with the contemporary theories of Marsilio Ficino and other neo-platonic thinkers linked to Raphael. Finally, according to Vasari, the scene includes Raphael himself, the Duke of Mantua, Zoroaster and some Evangelists.

However, as Heinrich Wölfflin observed, “it is quite wrong to attempt interpretations of the ‘School of Athens’ as an esoteric treatise … The all-important thing was the artistic motive which expressed a physical or spiritual state, and the name of the person was a matter of indifference” in Raphael’s time. What is evident is Raphael’s artistry in orchestrating a beautiful space, continuous with that of viewers in the Stanza, in which a great variety of human figures, each one expressing “mental states by physical actions”, interact, and are grouped in a “polyphony” unlike anything in earlier art, in the ongoing dialogue of Philosophy.

Sistine Chapel ceiling from Michelangelo

The Sistine Chapel ceiling, painted by Michelangelo between 1508 and 1512, at the commission of Pope Julius II, is a cornerstone work of High Renaissance art. The ceiling is that of the large Papal Chapel built within the Vatican between 1477 and 1480 by Pope Sixtus IV after whom it is named. The chapel is the location for Papal Conclaves and many important services.

The ceiling’s various painted elements form part of a larger scheme of decoration within the Chapel, which includes the large fresco The Last Judgment on the sanctuary wall, also by Michelangelo, wall paintings by several leading painters of the late 15th century including Sandro Botticelli, Domenico Ghirlandaio and Pietro Perugino, and a set of large tapestries by Raphael, the whole illustrating much of the doctrine of the Catholic Church.

Central to the ceiling decoration are nine scenes from the Book of Genesis of which the Creation of Adam is the best known, having an iconic standing equalled only by Leonardo da Vinci’s Mona Lisa, the hands of God and Adam being reproduced in countless imitations. The complex design includes several sets of individual figures, both clothed and naked, which allowed Michelangelo to fully demonstrate his skill in creating a huge variety of poses for the human figure, and have provided an enormously influential pattern book of models for other artists ever since.

Pope Julius II was a “warrior pope” who in his papacy undertook an aggressive campaign for political control, to unite and empower Italy under the leadership of the Church. He invested in symbolism to display his temporal power such as his procession, in the Classical manner, through a triumphal arch in a chariot after one of his many military victories. It was Julius who began the rebuilding of St. Peter’s Basilica in 1506, as the most potent symbol of the source of papal power.

In the same year, 1506, Julius II conceived a program to paint the ceiling of the Sistine Chapel. The walls of the chapel had been decorated twenty years earlier. The lowest of three levels is painted to resemble draped hangings, and was (and sometimes still is) hung on special occasions with the set of tapestries designed by Raphael. The middle level contains a complex scheme of frescoes illustrating the Life of Christ on the right side and the Life of Moses on the left side. It was carried out by some of the most renowned Renaissance painters: Botticelli, Ghirlandaio, Perugino, Pinturicchio, Signorelli and Cosimo Rosselli. The upper level of the walls contains the windows, between which are painted pairs of illusionistic niches with representations of the first thirty-two popes. A draft by Matteo d’Amelia indicates that the ceiling was painted blue like that of the Arena Chapel and decorated with gold stars, possibly representing the zodiacal constellations. It is probable that because the chapel was the site of regular meetings and Masses of an elite body of officials known as the Papal Chapel who would observe the decorations and interpret their theological and temporal significance, it was Pope Julius’ intention and expectation that the iconography of the ceiling was to be read with many layers of meaning.

Michelangelo, who was not primarily a painter but a sculptor, was reluctant to take on the work. Also, he was occupied with a very large sculptural commission for the Pope’s own tomb. The Pope was adamant, leaving Michelangelo no choice but to accept. But a war with the French broke out, diverting the attention of the Pope, and Michelangelo fled from Rome to continue sculpting. The tomb sculptures, however, were never to be finished because in 1508 the Pope returned to Rome victorious and summoned Michelangelo to begin work on the ceiling. The contract was signed on 10 May 1508.

The scheme proposed by the pope was for twelve large figures of the Apostles to occupy the pendentives. However Michelangelo negotiated for a grander, much more complex scheme and was finally permitted, in his own words, “to do as I liked”. His scheme for the ceiling eventually comprised some three hundred figures and took four years to execute, being completed in 1512. It is unknown and is the subject of much speculation among art historians as to whether Michelangelo was really able to “do as he liked”. It has been suggested that Egidio da Viterbo was a consultant for the Theology. Many writers consider that Michelangelo had the intellect, the Biblical knowledge and the powers of invention to have devised the scheme himself. This is supported by Condivi’s statement that Michelangelo read and reread the Old Testament while he was painting the ceiling, drawing his inspiration from the words of the scripture, rather than from the established traditions of sacral art. There was a total of 343 figures painted on the ceiling.
