Kanchipuram has been ruled by the Pallavas , the Medieval Cholas , the Later Cholas , the Later Pandyas , the Vijayanagara Empire , the Carnatic kingdom , and the British , who called the city "Conjeeveram". The city's historical monuments include the Kailasanathar Temple and
11319-462: The age of 32. His last letters to Hardy, written in January 1920, show that he was still continuing to produce new mathematical ideas and theorems. His " lost notebook ", containing discoveries from the last year of his life, caused great excitement among mathematicians when it was rediscovered in 1976. Ramanujan (literally, "younger brother of Rama ", a Hindu deity) was born on 22 December 1887 into
11466-575: The answer to the question posed in the Journal was simply 3, obtained by setting x = 2 , n = 1 , and a = 0 . Ramanujan wrote his first formal paper for the Journal on the properties of Bernoulli numbers . One property he discovered was that the denominators of the fractions of Bernoulli numbers (sequence A027642 in the OEIS ) are always divisible by six. He also devised a method of calculating B n based on previous Bernoulli numbers. One of these methods follows: It will be observed that if n
11613-519: The appointment on me. Attached to his application was a recommendation from E. W. Middlemast , a mathematics professor at the Presidency College , who wrote that Ramanujan was "a young man of quite exceptional capacity in Mathematics". Three weeks after he applied, on 1 March, Ramanujan learned that he had been accepted as a Class III, Grade IV accounting clerk, making 30 rupees per month. At his office, Ramanujan easily and quickly completed

12054-564: The best scores in the district. That year, Ramanujan entered Town Higher Secondary School , where he encountered formal mathematics for the first time. A child prodigy by age 11, he had exhausted the mathematical knowledge of two college students who were lodgers at his home. He was later lent a book written by S. L. Loney on advanced trigonometry. He mastered this by the age of 13 while discovering sophisticated theorems on his own. By 14, he received merit certificates and academic awards that continued throughout his school career, and he assisted
12201-479: The city daily at five collection points covering the whole of the city. The sewage system in the city was implemented in 1975; Kanchipuram was identified as one of the hyper endemic cities in 1970. Underground drainage covers 82% of roads in the city, and is divided into east and west zones for internal administration. Kanchipuram is traditionally a centre of religious education for the Hindu, Jainism and Buddhism faiths. The Buddhist monasteries acted as nucleus of
12348-649: The city in 1672, but lost it to Bijapur three years later. In 1676, Shivaji arrived in Kanchipuram at the invitation of the Golconda Sultanate in order to drive out the Bijapur forces. His campaign was successful and Kanchipuram was held by the Golconda Sultanate until its conquest by the Mughal Empire led by Aurangazeb in October 1687. In the course of their southern campaign, the Mughals defeated
12495-518: The city is like a girdle to the earth. The earliest Sanskrit inscriptions from the Gupta period (early 4th century-CE to late 5th century-CE) denote the city as Kanchipuram , where King Visnugopa was defeated by Samudragupta. Patanjali (150 BCE or 2nd century BCE) refers to the city in his Mahabhasya as Kanchipuraka . The city was referred to by various names like Kanchi , Kanchipedu and Kanchipuram . The Pallava inscriptions from (250–355) and
12642-571: The city. A second invasion ended disastrously for Pulakesin II, who was forced to retreat to his capital Vatapi which was besieged and Pulakesin II was killed by Narasimhavarman I (630–668), son of Mahendravarman I (600–630), at the Battle of Vatapi . Under the Pallavas, Kanchipuram flourished as a centre of Hindu and Buddhist learning. King Narasimhavarman II built the city's important Hindu temples,
12789-732: The city. Industrial developments occupy around 65 hectares (160 acres), where most of the handloom spinning, silk weaving, dyeing and rice production units are located. 89.06 hectares (220.1 acres) are used for transport and communications infrastructure, including bus stands, roads, streets and railways lines. The major occupations of Kanchipuram are silk sari weaving and agriculture. As of 2008, an estimated 5,000 families were involved in sari production. The main industries are cotton production, light machinery and electrical goods manufacturing, and food processing. There are 25 silk and cotton yarn industries, 60 dyeing units, 50 rice mills and 42 other industries in Kanchipuram. Another important occupation
12936-595: The classical Tamil language Sangam literature dated 300 BCE like Manimegalai and Perumpāṇāṟṟuppaṭai . While it is widely accepted that Kanchipuram had served as an Early Chola capital, the claim has been contested by Indian historian P. T. Srinivasa Iyengar who wrote that the Tamil culture of the Sangam period did not spread through the Kanchipuram district and cites the Sanskritic origins of its name in support of his claim. Kanchipuram grew in importance when
13083-739: The deity of Namagiri , commanded her "to stand no longer between her son and the fulfilment of his life's purpose". On 17 March 1914, Ramanujan travelled to England by ship, leaving his wife to stay with his parents in India. Ramanujan departed from Madras aboard the S.S. Nevasa on 17 March 1914. When he disembarked in London on 14 April, Neville was waiting for him with a car. Four days later, Neville took him to his house on Chesterton Road in Cambridge. Ramanujan immediately began his work with Littlewood and Hardy. After six weeks, Ramanujan moved out of Neville's house and took up residence on Whewell's Court,
13230-951: The district collector for Nellore and the secretary of the Indian Mathematical Society. Rao was impressed by Ramanujan's research but doubted that it was his own work. Ramanujan mentioned a correspondence he had with Professor Saldhana, a notable Bombay mathematician, in which Saldhana expressed a lack of understanding of his work but concluded that he was not a fraud. Ramanujan's friend C. V. Rajagopalachari tried to quell Rao's doubts about Ramanujan's academic integrity. Rao agreed to give him another chance, and listened as Ramanujan discussed elliptic integrals , hypergeometric series , and his theory of divergent series , which Rao said ultimately convinced him of Ramanujan's brilliance. When Rao asked him what he wanted, Ramanujan replied that he needed work and financial support. Rao consented and sent him to Madras. He continued his research with Rao's financial aid. With Aiyer's help, Ramanujan had his work published in
13377-500: The earliest known mathematicians was Thales of Miletus ( c. 624 – c. 546 BC ); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry , by deriving four corollaries to Thales's theorem . The number of known mathematicians grew when Pythagoras of Samos ( c. 582 – c. 507 BC ) established
13524-515: The first product in India to carry this label. The silk trade in Kanchipuram began when King Raja Raja Chola I (985–1014) invited weavers from Saurashtra , Gujarat to migrate to Kanchi. The craft increased with the mass migration of weavers from Andhra Pradesh in the 15th century during the Vijayanagara rule . The city was razed during the French siege of 1757, but weaving re-emerged in

His successor, Achyuta Deva Raya, reportedly had himself weighed against pearls in Kanchipuram and distributed the pearls amongst the poor. Throughout the second half of the 16th and first half of the 17th centuries, the Aravidu Dynasty tried to maintain a semblance of authority in
14406-672: The granite required for the Varadaraja Perumal Temple might have been obtained from the Sivaram Hills located 10 miles east of Kanchipuram. The area is classified as a Seismic Zone II region , and earthquakes of up to magnitude 6 on the Richter Scale may be expected. Kanchipuram is subdivided into two divisions – Most of the Shiva temples were in Big Kanchipuram while most of
14553-467: The imagination to invent them". Hardy asked a colleague, J. E. Littlewood , to take a look at the papers. Littlewood was amazed by Ramanujan's genius. After discussing the papers with Littlewood, Hardy concluded that the letters were "certainly the most remarkable I have received" and that Ramanujan was "a mathematician of the highest quality, a man of altogether exceptional originality and power". One colleague, E. H. Neville , later remarked that "No one who
14700-633: The imposing problems presented in related scientific fields. With professional focus on a wide variety of problems, theoretical systems, and localized constructs, applied mathematicians work regularly in the study and formulation of mathematical models . Mathematicians and applied mathematicians are considered to be two of the STEM (science, technology, engineering, and mathematics) careers. The discipline of applied mathematics concerns itself with mathematical methods that are typically used in science, engineering, business, and industry; thus, "applied mathematics"
14847-548: The inscriptions of the Chalukya dynasty refer the city as Kanchipura . Jaina Kanchi refers to the area around Tiruparutti Kundram. During the British rule, the city was known as Conjeevaram and later as Kanchipuram . The municipal administration was renamed Kancheepuram , while the district and city retains the name Kanchipuram . It finds its mention in Pāṇini's Ashtadhyayi as Kanchi-prastha and in several Puranas. It
14994-407: The journal, adding, "The following theorem is due to S. Ramanujan, the mathematics student of Madras University." Later in November, British Professor Edward B. Ross of Madras Christian College , whom Ramanujan had met a few years before, stormed into his class one day with his eyes glowing, asking his students, "Does Ramanujan know Polish?" The reason was that in one paper, Ramanujan had anticipated
15141-580: The kind of research done by private and individual scholars in Great Britain and France. In fact, Rüegg asserts that the German system is responsible for the development of the modern research university because it focused on the idea of "freedom of scientific research, teaching and study." Mathematicians usually cover a breadth of topics within mathematics in their undergraduate education , and then proceed to specialize in topics of their own choice at
15288-474: The king of Prussia , Fredrick William III , to build a university in Berlin based on Friedrich Schleiermacher 's liberal ideas; the goal was to demonstrate the process of the discovery of knowledge and to teach students to "take account of fundamental laws of science in all their thinking." Thus, seminars and laboratories started to evolve. British universities of this period adopted some approaches familiar to
15435-445: The late 18th century. All major nationalised banks such as Vijaya Bank , State Bank of India , Indian Bank , Canara Bank , Punjab National Bank , Dena Bank and private banks like ICICI Bank have branches in Kanchipuram. All these banks have their Automated teller machines located in various parts of the city. Kanchipuram has more than the national average rate of child labour and bonded labour. The local administration
15582-658: The leading professional mathematicians in his work, but failed for the most part. What he had to show them was too novel, too unfamiliar, and additionally presented in unusual ways; they could not be bothered". Seeking mathematicians who could better understand his work, in 1913 he began a mail correspondence with the English mathematician G. H. Hardy at the University of Cambridge , England. Recognising Ramanujan's work as extraordinary, Hardy arranged for him to travel to Cambridge. In his notes, Hardy commented that Ramanujan had produced groundbreaking new theorems , including some that "defeated me completely; I had never seen anything in
15729-599: The least like them before", and some recently proven but highly advanced results. During his short life, Ramanujan independently compiled nearly 3,900 results (mostly identities and equations ). Many were completely novel; his original and highly unconventional results, such as the Ramanujan prime , the Ramanujan theta function , partition formulae and mock theta functions , have opened entire new areas of work and inspired further research. Of his thousands of results, most have been proven correct. The Ramanujan Journal ,
15876-442: The marriage, Ramanujan developed a hydrocele testis . The condition could be treated with a routine surgical operation that would release the blocked fluid in the scrotal sac, but his family could not afford the operation. In January 1910, a doctor volunteered to do the surgery at no cost. After his successful surgery, Ramanujan searched for a job. He stayed at a friend's house while he went from door to door around Madras looking for
16023-574: The maximum. He received a scholarship to study at Government Arts College, Kumbakonam , but was so intent on mathematics that he could not focus on any other subjects and failed most of them, losing his scholarship in the process. In August 1905, Ramanujan ran away from home, heading towards Visakhapatnam , and stayed in Rajahmundry for about a month. He later enrolled at Pachaiyappa's College in Madras. There, he passed in mathematics, choosing only to attempt questions that appealed to him and leaving
16170-568: The necessary educational background and foundation to be accepted by mathematicians. Although Hill did not offer to take Ramanujan on as a student, he gave thorough and serious professional advice on his work. With the help of friends, Ramanujan drafted letters to leading mathematicians at Cambridge University. The first two professors, H. F. Baker and E. W. Hobson , returned Ramanujan's papers without comment. On 16 January 1913, Ramanujan wrote to G. H. Hardy , whom he knew from studying Orders of Infinity (1910). Coming from an unknown mathematician,
16317-506: The need for mathematically rigorous proofs was recognised. Hardy was an atheist and an apostle of proof and mathematical rigour, whereas Ramanujan was a deeply religious man who relied very strongly on his intuition and insights. Hardy tried his best to fill the gaps in Ramanujan's education and to mentor him in the need for formal proofs to support his results, without hindering his inspiration—a conflict that neither found easy. Ramanujan
16464-505: The nine pages of mathematics made Hardy initially view Ramanujan's manuscripts as a possible fraud. Hardy recognised some of Ramanujan's formulae but others "seemed scarcely possible to believe". One of the theorems Hardy found amazing was on the bottom of page three (valid for 0 < a < b + 1 / 2 ): Hardy was also impressed by some of Ramanujan's other work relating to infinite series: The first result had already been determined by G. Bauer in 1859. The second

Actuaries also address financial questions, including those involving the level of pension contributions required to produce a certain retirement income and the way in which a company should invest resources to maximize its return on investments in light of potential risk. Using their broad knowledge, actuaries help design and price insurance policies, pension plans, and other financial strategies in
17199-484: The real world, many applied mathematicians draw on tools and techniques that are often considered to be "pure" mathematics. On the other hand, many pure mathematicians draw on natural and social phenomena as inspiration for their abstract research. Many professional mathematicians also engage in the teaching of mathematics. Duties may include: Many careers in mathematics outside of universities involve consulting. For instance, actuaries assemble and analyze data to estimate

17493-471: The rest unanswered, but performed poorly in other subjects, such as English, physiology, and Sanskrit. Ramanujan failed his Fellow of Arts exam in December 1906 and again a year later. Without an FA degree, he left college and continued to pursue independent research in mathematics, living in extreme poverty and often on the brink of starvation. In 1910, after a meeting between the 23-year-old Ramanujan and
17640-493: The same. I have passed the Matriculation Examination and studied up to the F.A. but was prevented from pursuing my studies further owing to several untoward circumstances. I have, however, been devoting all my time to Mathematics and developing the subject. I can say I am quite confident I can do justice to my work if I am appointed to the post. I therefore beg to request that you will be good enough to confer
17787-495: The sanctum. Robert Clive is said to have presented an emerald necklace to the temple. It is called the Clive Makarakandi and is still used to decorate the deity on ceremonial occasions. This temple is the main reason for the city to get its name Kanchi . In the Sanskrit the word is split into two: ka and anchi. Ka means Brahma and anchi means worship, showing that Kanchi stands for the place where Varadharaja Perumal
17934-426: The school in the logistics of assigning its 1,200 students (each with differing needs) to its approximately 35 teachers. He completed mathematical exams in half the allotted time, and showed a familiarity with geometry and infinite series . Ramanujan was shown how to solve cubic equations in 1902. He would later develop his own method to solve the quartic . In 1903, he tried to solve the quintic , not knowing that it
18081-403: The seventeenth century at Oxford with the scientists Robert Hooke and Robert Boyle , and at Cambridge where Isaac Newton was Lucasian Professor of Mathematics & Physics . Moving into the 19th century, the objective of universities all across Europe evolved from teaching the "regurgitation of knowledge" to "encourag[ing] productive thinking." In 1810, Alexander von Humboldt convinced
18228-607: The southern parts after losing their northern territories in the Battle of Talikota . Venkata II (1586–1614) tried to revive the Vijayanagara Empire, but the kingdom relapsed into confusion after his death and rapidly fell apart after the Vijayanagara king Sriranga III 's defeat by the Golconda and Bijapur sultanates in 1646. After the fall of the Vijayanagara Empire, Kanchipuram endured over two decades of political turmoil. The Golconda Sultanate gained control of
18375-527: The tallest temple towers in India. The temple is one of five called Pancha Bhoota Stalams , which represent the manifestation of the five prime elements of nature; namely land, water, air, sky, and fire.

Varadharaja Perumal Temple was renovated by the Cholas in 1053 and it was expanded during the reigns of the great Chola kings Kulottunga Chola I and Vikrama Chola . In the 14th century another wall and a gopura was built by the later Chola kings. It is one of the Divya Desams , the 108 holy abodes of Maha Vishnu. The temple features carved lizards, one plated with gold and another with silver, over
18669-546: The third week of February, Hardy contacted the Indian Office to plan for Ramanujan's trip to Cambridge. Secretary Arthur Davies of the Advisory Committee for Indian Students met with Ramanujan to discuss the overseas trip. In accordance with his Brahmin upbringing, Ramanujan refused to leave his country to " go to a foreign land ", and his parents were also opposed for the same reason. Meanwhile, he sent Hardy
18816-460: The verandah in the front yard, garden in the backyard, ventilation facilities and drainage of rainwater were all introduced for the first time, while the Tiruvekka temple and houses of agricultural labourers were situated outside the city. There were provisions in the city's outskirts for training the cavalry and infantry. During the Chola era, Kanchipuram was not the capital, but the kings had
18963-594: The work he was given and spent his spare time doing mathematical research. Ramanujan's boss, Sir Francis Spring , and S. Narayana Iyer, a colleague who was also treasurer of the Indian Mathematical Society, encouraged Ramanujan in his mathematical pursuits. In the spring of 1913, Narayana Iyer, Ramachandra Rao and E. W. Middlemast tried to present Ramanujan's work to British mathematicians. M. J. M. Hill of University College London commented that Ramanujan's papers were riddled with holes. He said that although Ramanujan had "a taste for mathematics, and some ability", he lacked
19110-443: The work of a Polish mathematician whose paper had just arrived in the day's mail. In his quarterly papers, Ramanujan drew up theorems to make definite integrals more easily solvable. Working off Giuliano Frullani's 1821 integral theorem, Ramanujan formulated generalisations that could be made to evaluate formerly unyielding integrals. Hardy's correspondence with Ramanujan soured after Ramanujan refused to come to England. Hardy enlisted
19257-943: Was Al-Khawarizmi . A notable feature of many scholars working under Muslim rule in medieval times is that they were often polymaths. Examples include the work on optics , maths and astronomy of Ibn al-Haytham . The Renaissance brought an increased emphasis on mathematics and science to Europe. During this period of transition from a mainly feudal and ecclesiastical culture to a predominantly secular one, many notable mathematicians had other occupations: Luca Pacioli (founder of accounting ); Niccolò Fontana Tartaglia (notable engineer and bookkeeper); Gerolamo Cardano (earliest founder of probability and binomial expansion); Robert Recorde (physician) and François Viète (lawyer). As time passed, many mathematicians gravitated towards universities. An emphasis on free thinking and experimentation had begun in Britain's oldest universities beginning in
19404-510: Was impossible to solve with radicals. In 1903, when he was 16, Ramanujan obtained from a friend a library copy of A Synopsis of Elementary Results in Pure and Applied Mathematics , G. S. Carr 's collection of 5,000 theorems. Ramanujan reportedly studied the contents of the book in detail. The next year, Ramanujan independently developed and investigated the Bernoulli numbers and calculated
19551-557: Was a year and a half old, his mother gave birth to a son, Sadagopan, who died less than three months later. In December 1889, Ramanujan contracted smallpox , but recovered, unlike the 4,000 others who died in a bad year in the Thanjavur district around this time. He moved with his mother to her parents' house in Kanchipuram , near Madras (now Chennai ). His mother gave birth to two more children, in 1891 and 1894, both of whom died before their first birthdays. On 1 October 1892, Ramanujan
19698-712: Was active in efforts to increase his public recognition; prominent mathematicians, including George Andrews, Bruce C. Berndt and Béla Bollobás made it a point to visit her while in India. She died at her Triplicane residence in 1994. A 1994 analysis of Ramanujan's medical records and symptoms by D. A. B. Young concluded that his medical symptoms —including his past relapses, fevers, and hepatic conditions—were much closer to those resulting from hepatic amoebiasis , an illness then widespread in Madras, than tuberculosis. He had two episodes of dysentery before he left India. When not properly treated, amoebic dysentery can lie dormant for years and lead to hepatic amoebiasis, whose diagnosis
19845-609: Was awarded a Bachelor of Arts by Research degree (the predecessor of the PhD degree) in March 1916 for his work on highly composite numbers , sections of the first part of which had been published the preceding year in the Proceedings of the London Mathematical Society . The paper was more than 50 pages long and proved various properties of such numbers. Hardy disliked this topic area but remarked that though it engaged with what he called
19992-952: Was diagnosed with tuberculosis and a severe vitamin deficiency, and confined to a sanatorium . He attempted suicide in late 1917 or early 1918 by jumping on the tracks of a London underground station. Scotland Yard arrested him for attempting suicide (which was a crime), but released him after Hardy intervened. In 1919, Ramanujan returned to Kumbakonam , Madras Presidency , where he died in 1920 aged 32. After his death, his brother Tirunarayanan compiled Ramanujan's remaining handwritten notes, consisting of formulae on singular moduli, hypergeometric series and continued fractions. In his last days, though in severe pain, "he continued doing his mathematics filling sheet after sheet with numbers", Janaki Ammal recounts. Ramanujan's widow, Smt. Janaki Ammal, moved to Bombay . In 1931, she returned to Madras and settled in Triplicane , where she supported herself on
20139-564: Was elected "for his investigation in elliptic functions and the Theory of Numbers." On 13 October 1918, he was the first Indian to be elected a Fellow of Trinity College, Cambridge . Ramanujan had numerous health problems throughout his life. His health worsened in England; possibly he was also less resilient due to the difficulty of keeping to the strict dietary requirements of his religion there and because of wartime rationing in 1914–18 . He
20286-480: Was enrolled at the local school. After his maternal grandfather lost his job as a court official in Kanchipuram, Ramanujan and his mother moved back to Kumbakonam , and he was enrolled in Kangayan Primary School. When his paternal grandfather died, he was sent back to his maternal grandparents, then living in Madras. He did not like school in Madras, and tried to avoid attending. His family enlisted
20433-419: Was in the mathematical circles in Cambridge at that time can forget the sensation caused by this letter... not one [theorem] could have been set in the most advanced mathematical examination in the world". On 8 February 1913, Hardy wrote Ramanujan a letter expressing interest in his work, adding that it was "essential that I should see proofs of some of your assertions". Before his letter arrived in Madras during
20580-464: Was known in early Tamil and Sanskrit literature as Kanchi or Kachipedu . In the Sanskrit the word is split into two: ka and anchi. Ka means Brahma and anchi means worship, showing that Kanchi stands for the place where Varadharaja Perumal was worshipped by Brahma. Brahma has sculpted Athi Varadhar and worshipped here. In Sanskrit the term Kanci means girdle and explanation is given that
20727-506: Was new to Hardy, and was derived from a class of functions called hypergeometric series , which had first been researched by Euler and Gauss. Hardy found these results "much more intriguing" than Gauss's work on integrals. After seeing Ramanujan's theorems on continued fractions on the last page of the manuscripts, Hardy said the theorems "defeated me completely; I had never seen anything in the least like them before", and that they "must be true, because, if they were not true, no one would have
20874-465: Was not then well established. At the time, if properly diagnosed, amoebiasis was a treatable and often curable disease; British soldiers who contracted it during the First World War were being successfully cured of amoebiasis around the time Ramanujan left England. While asleep, I had an unusual experience. There was a red screen formed by flowing blood, as it were. I was observing it. Suddenly
21021-436: Was not unusual then for marriages to be arranged with girls at a young age. Janaki was from Rajendram, a village close to Marudur ( Karur district ) Railway Station. Ramanujan's father did not participate in the marriage ceremony. As was common at that time, Janaki continued to stay at her maternal home for three years after marriage, until she reached puberty. In 1912, she and Ramanujan's mother joined Ramanujan in Madras. After
21168-431: Was ongoing throughout the reign of certain caliphs, and it turned out that certain scholars became experts in the works they translated, and in turn received further support for continuing to develop certain sciences. As these sciences received wider attention from the elite, more scholars were invited and funded to study particular sciences. An example of a translator and mathematician who benefited from this type of support
21315-526: Was part of the Chennai South constituency . This constituency is reserved for Scheduled Castes (SC) candidates. K. Maragatham from the All India Anna Dravida Munnetra Kazhagam is the current Member of Parliament for the constituency. Indian writer, politician and founder of the DMK, C. N. Annadurai , was born and raised in Kanchipuram. He was the first member of a Dravidian party to hold that post and
21462-506: Was the first non-Congress leader to form a majority government in post-colonial India . Policing in the city is provided by the Kanchipuram sub-division of the Tamil Nadu Police headed by a Deputy Superintendent of Police. The force's special units include prohibition enforcement, district crime, social justice and human rights, district crime records and special branch that operate at the district level police division, which
21609-688: Was worshipped by Brahma. Brahma has sculpted Athi Varadhar and worshipped here. Yathothkari Perumal Temple is the birthplace of the Alvar saint, Poigai Alvar . The temple finds mention in Perumpaanatrupadai written by Patanjali. There is a mention about the temple in Silappatikaram (2nd-3rd century CE), Patanjali Mahabharatham and Tolkāppiyam (3rd century BCE). The temple is revered in Nalayira Divya Prabandham,
