A barrel vault , also known as a tunnel vault , wagon vault or wagonhead vault , is an architectural element formed by the extrusion of a single curve (or pair of curves, in the case of a pointed barrel vault) along a given distance. The curves are typically circular in shape, lending a semi-cylindrical appearance to the total design. The barrel vault is the simplest form of a vault : effectively a series of arches placed side by side (i.e., one after another). It is a form of barrel roof .
77-587: A gopuram or gopura ( Tamil : கோபுரம், Telugu : గోపురం, Kannada : ಗೋಪುರ, Malayalam : ഗോപുരം) is a monumental entrance tower, usually ornate, at the entrance of a Hindu temple , in the South Indian architecture of the southern Indian states of Tamil Nadu , Andhra Pradesh , Kerala , Karnataka , and Telangana , and Sri Lanka . In other areas of India they are much more modest, while in Southern Indian temples they are very often by far
154-455: A Tamira Samghatta ( Tamil confederacy ) The Samavayanga Sutra dated to the 3rd century BCE contains a reference to a Tamil script named 'Damili'. Southworth suggests that the name comes from tam-miḻ > tam-iḻ "self-speak", or "our own speech". Kamil Zvelebil suggests an etymology of tam-iḻ , with tam meaning "self" or "one's self", and " -iḻ " having the connotation of "unfolding sound". Alternatively, he suggests
231-404: A finite element algorithm to calculate gravity induced stresses from the self weight of an arched system. In fact, for structural engineers, analysis of the barrel vault has become a benchmark test of a structural engineering computer model "because of the complex membrane and inextensional bending states of stress" involved. In terms of comparison to other vaulting techniques, the barrel vault
308-468: A lexical root to which one or more affixes are attached. Most Tamil affixes are suffixes . Tamil suffixes can be derivational suffixes, which either change the part of speech of the word or its meaning, or inflectional suffixes, which mark categories such as person , number , mood , tense , etc. There is no absolute limit on the length and extent of agglutination , which can lead to long words with many suffixes, which would require several words or
385-469: A span of only two metres. In these early instances, the barrel vault was chiefly used for underground structures such as drains and sewers , though several buildings of the great Late Egyptian mortuary palace - temple of Ramesseum were also vaulted in this way. Recent archaeological evidence discovered at the Morgantina site (in the province of Enna ) shows that the aboveground barrel vault
462-484: A , as with other Indic scripts . This inherent vowel is removed by adding a tittle called a puḷḷi , to the consonantal sign. For example, ன is ṉa (with the inherent a ) and ன் is ṉ (without a vowel). Many Indic scripts have a similar sign, generically called virama , but the Tamil script is somewhat different in that it nearly always uses a visible puḷḷi to indicate a 'dead consonant' (a consonant without
539-759: A 2001 survey, there were 1,863 newspapers published in Tamil, of which 353 were dailies. Tamil is the primary language of the majority of the people residing in Tamil Nadu , Puducherry , (in India) and in the Northern and Eastern provinces of Sri Lanka . The language is spoken among small minority groups in other states of India which include Karnataka , Telangana , Andhra Pradesh , Kerala , Maharashtra , Gujarat , Delhi , Andaman and Nicobar Islands in India and in certain regions of Sri Lanka such as Colombo and
616-587: A classical language by the Indian government and holds official status in Tamil Nadu, Puducherry and Singapore. The earliest extant Tamil literary works and their commentaries celebrate the Pandiyan Kings for the organization of long-termed Tamil Sangams , which researched, developed and made amendments in Tamil language. Even though the name of the language which was developed by these Tamil Sangams
693-409: A derivation of tamiḻ < tam-iḻ < * tav-iḻ < * tak-iḻ , meaning in origin "the proper process (of speaking)". However, this is deemed unlikely by Southworth due to the contemporary use of the compound 'centamiḻ', which means refined speech in the earliest literature. The Tamil Lexicon of University of Madras defines the word "Tamil" as "sweetness". S. V. Subramanian suggests
770-574: A finial. The form began rather modestly in the 10th century, as at Shore Temple , Mamallapuram , with the 11th century Brihadeeswarar Temple in Thanjavur marking a crucial step forward with two multi-storey gopurams from that period, much larger than any earlier ones, though much smaller than the main tower (vimanam) of the temple. The four gopurams of the Thillai Nataraja Temple, Chidambaram are important early examples, begun in
847-501: A hub of the urban life, these gateways became a dominant feature of a temple's outer appearance, eventually overshadowing the inner sanctuary which became obscured from view by the gopuram's colossal size and courtyards. It also dominated the inner sanctum in amount of ornamentation. Often a shrine has more than one gopuram. They also appear in architecture outside India, especially Khmer architecture , as at Angkor Wat . A large Dravidian-style temple, or koil, may have multiple gopurams as

With a barrel vault design the vectors of pressure result in a downward force on the crown while the lower portions of the arches realise a lateral force pushing outwards. As an outcome this form of design is subject to failure unless the sides are anchored or buttressed to very heavy building elements or substantial earthwork sidings. For example, at Muchalls Castle in Scotland , adjacent walls to

Old Tamil is the period of the Tamil language spanning the 3rd century BCE to the 8th century CE. The earliest records in Old Tamil are short inscriptions from 300 BCE to 700 CE. These inscriptions are written in a variant of the Brahmi script called Tamil-Brahmi . The earliest long text in Old Tamil
1078-518: A number of sound changes, in particular, a tendency to lower high vowels in initial and medial positions, and the disappearance of vowels between plosives and between a plosive and rhotic. Contact with European languages affected written and spoken Tamil. Changes in written Tamil include the use of European-style punctuation and the use of consonant clusters that were not permitted in Middle Tamil. The syntax of written Tamil has also changed, with
1155-535: A relative parallel to Tamil, even as Tamil has undergone some changes in modern ways of speaking. According to Hindu legend, Tamil or in personification form Tamil Thāi (Mother Tamil) was created by Lord Shiva . Murugan , revered as the Tamil God, along with sage Agastya , brought it to the people. Tamil, like other Dravidian languages, ultimately descends from the Proto-Dravidian language , which
1232-541: A return to stone barrel vaults was seen for the first great cathedrals; their interiors were fairly dark, due to thick, heavy walls needed to support the vault. One of the largest and most famous churches enclosed from above by a vast barrel vault was the church of Cluny Abbey , built between the 11th and 12th centuries. In 13th and 14th centuries, with the advance of the new Gothic style, barrel vaulting became almost extinct in constructions of great Gothic cathedrals; groin vaults reinforced by stone ribs were mostly used in
1309-501: A sentence in English. To give an example, the word pōkamuṭiyātavarkaḷukkāka (போகமுடியாதவர்களுக்காக) means "for the sake of those who cannot go" and consists of the following morphemes : போக pōka go முடி muṭi accomplish Barrel vault As with all arch -based constructions, there is an outward thrust generated against the walls underneath a barrel vault. There are several mechanisms for absorbing this thrust. One

In addition, with the creation in October 2004 of a legal status for classical languages by the Government of India and following a political campaign supported by several Tamil associations, Tamil became the first legally recognised Classical language of India. The recognition was announced by the contemporaneous President of India , Abdul Kalam , who
1540-463: A variety of dialects that are all collectively known as Brahmin Tamil . These dialects tend to have softer consonants (with consonant deletion also common). These dialects also tend to have many Sanskrit loanwords. Tamil in Sri Lanka incorporates loan words from Portuguese , Dutch , and English. In addition to its dialects, Tamil exhibits different forms: a classical literary style modelled on
1617-570: A vault is a tunnel vault found under the Sumerian ziggurat at Nippur in Babylonia , ascribed to about 4000 BC, which was built from fired bricks amalgamated with clay mortar . The earliest tunnel vaults in Egypt are found at Requagnah and Denderah , from around 3500 BC in the predynastic era. These were built with sun-dried brick in three rings over passages descending to tombs with

In other Indic scripts, it is generally preferred to use a ligature or a half form to write a syllable or a cluster containing a dead consonant, although writing it with a visible virama is also possible. The Tamil script does not differentiate voiced and unvoiced plosives . Instead, plosives are articulated with voice depending on their position in a word, in accordance with the rules of Tamil phonology . In addition to
1771-412: Is Malayalam ; the two began diverging around the 9th century CE. Although many of the differences between Tamil and Malayalam demonstrate a pre-historic divergence of the western dialect, the process of separation into a distinct language, Malayalam, was not completed until sometime in the 13th or 14th century. Additionally Kannada is also relatively close to the Tamil language and shares the format of
1848-604: Is also called the Vimanam , although in the south it is typically smaller than the gopurams in large temples. The Tamil derivation is from the two words: கோ (kō) and புறம் (puram) meaning 'king' and 'exterior' respectively. It originates from the Sangam age when it was known as ஓங்கு நிலை வாயில் (ōnggu nilai vāyil) meaning 'imperishable gateway'. The Telugu derivation is from the two words : కోపు (Kōpu) and అరం (Araṁ) meaning "Top" and "to exist". An alternative derivation
1925-457: Is based on the dialect of Jaffna . After Tamil Brahmi fell out of use, Tamil was written using a script called vaṭṭeḻuttu amongst others such as Grantha and Pallava . The current Tamil script consists of 12 vowels , 18 consonants and one special character, the āytam . The vowels and consonants combine to form 216 compound characters, giving a total of 247 characters (12 + 18 + 1 + (12 × 18)). All consonants have an inherent vowel
2002-563: Is extensively described in the oldest known grammar book for Tamil, the Tolkāppiyam . Modern Tamil writing is largely based on the 13th-century grammar Naṉṉūl which restated and clarified the rules of the Tolkāppiyam , with some modifications. Traditional Tamil grammar consists of five parts, namely eḻuttu , col , poruḷ , yāppu , aṇi . Of these, the last two are mostly applied in poetry. Tamil words consist of

Dr. Sthapati explains the meaning of the words gopuram and vimanam thus. Vimanam means measure, indicating the number of measures made in the construction and design of that structure. Gopuram consist of two words, gawa and puram, meaning

In phonological terms, the most important shifts were the virtual disappearance of the aytam (ஃ), an old phoneme, the coalescence of the alveolar and dental nasals, and the transformation of the alveolar plosive into a rhotic . In grammar, the most important change
2233-409: Is generally used in formal writing and speech. For instance, it is the language of textbooks, of much of Tamil literature and of public speaking and debate. In recent times, however, koṭuntamiḻ has been making inroads into areas that have traditionally been considered the province of centamiḻ . Most contemporary cinema, theatre and popular entertainment on television and radio, for example,

The increasing use of koṭuntamiḻ in modern times has led to the emergence of unofficial 'standard' spoken dialects. In India, the 'standard' koṭuntamiḻ , rather than on any one dialect, but has been significantly influenced by the dialects of Thanjavur and Madurai . In Sri Lanka, the standard

The barrel vault structure must rest on long walls creating less stable lateral stress, whereas the groin vault design can direct stresses almost purely vertically on the apexes. There are numerous contemporary examples of barrel vault design in Victorian and modern architecture , including: Beyond the classical use of

The earliest attested use of the name is found in Tholkappiyam , which is dated as early as late 2nd century BCE. The Hathigumpha inscription , inscribed around a similar time period (150 BCE), by Kharavela , the Jain king of Kalinga , also refers to
2541-771: Is not always consistently applied. ISO 15919 is an international standard for the transliteration of Tamil and other Indic scripts into Latin characters. It uses diacritics to map the much larger set of Brahmic consonants and vowels to Latin script , and thus the alphabets of various languages, including English. Apart from the usual numerals, Tamil has numerals for 10, 100 and 1000. Symbols for day, month, year, debit, credit, as above, rupee, and numeral are present as well. Tamil also uses several historical fractional signs. /f/ , /z/ , /ʂ/ and /ɕ/ are only found in loanwords and may be considered marginal phonemes, though they are traditionally not seen as fully phonemic. Tamil has two diphthongs : /aɪ̯/ ஐ and /aʊ̯/ ஔ ,

In many of the monasteries, a natural solution was cloisters which could have high barrel-vaulted construction with an open courtyard to allow ample lighting. Since 1996 structural engineers have applied Newtonian mechanics to calculate numeric stress loads for ancient stonework barrel vaults. These analyses have typically used

In 2004, a number of skeletons were found buried in earthenware urns dating from at least 696 BCE in Adichanallur . Some of these urns contained writing in Tamil Brahmi script, and some contained skeletons of Tamil origin. Between 2017 and 2018, 5,820 artifacts have been found in Keezhadi . These were sent to Beta Analytic in Miami , Florida , for Accelerator Mass Spectrometry (AMS) dating. One sample containing Tamil-Brahmi inscriptions

These applications arise in the fields of surgery , skylight design, children's toys and microstructure design (such as bus shelters). While none of these applications rival the majesty of
3696-425: The barrel vaulted chambers are up to 4.6 m (15 ft) thick, adding the buttressing strength needed to secure the curved design. The inherent difficulty of adequately lighting barrel vaulted structures has been widely acknowledged. The intrinsic engineering issue is the need to avoid fenestration punctures in stonework barrel vaults. Such openings could compromise the integrity of the entire arch system. Thus

Although Tamil dialects do not differ significantly in their vocabulary, there are a few exceptions. The dialects spoken in Sri Lanka retain many words and grammatical forms that are not in everyday use in India, and use many other words slightly differently. Tamil dialects include Central Tamil dialect , Kongu Tamil , Madras Bashai , Madurai Tamil , Nellai Tamil , Kumari Tamil in India ; Batticaloa Tamil dialect , Jaffna Tamil dialect , Negombo Tamil dialect in Sri Lanka; and Malaysian Tamil in Malaysia.
