‘Sangam-era site at Keezhadi is as complex as Indus Valley, proof of a glorious Tamil civilisation’

In an interview to Scroll.in, Amarnath Ramakrishna, who led the ASI project before he was transferred, talks about why the findings could rewrite history.


In 2015, the Archaeological Survey of India team carrying out excavations in Keezhadi, near Madurai struck gold – they found the first concrete proof of the existence of a complex and sophisticated urban settlement in ancient Tamil Nadu. Several artefacts found at the site linked it to the Sangam era, a period from 4th Century BCE to 2th century CE widely regarded as a golden era for Tamil culture.

Archaeologist Amarnath Ramakrishna led the team that excavated close to 102 trenches in a 100-acre plot. But in March, the ASI decided to transfer the officer to Guwahati from the Bengaluru office where he was posted, against his will. He challenged the transfer order before the Central Administrative Tribunal, but it ruled against him. A team is carrying forward the excavation at the Keezhadi site, which now in its third year.

The transfer, however, kicked up a storm in the state. Political parties in Tamil Nadu, including the Dravida Munnetra Kazhagam, accused the Centre of deliberately trying to derail the excavation as the discoveries made those on the Hindu Right uncomfortable. The parties said Keezhadi could prove their long-held belief that Tamil Nadu may have had a non-Vedic, independent ancient civilisation, something that could challenge the notion of Vedic roots of all of Hinduism.

In an interview to Scroll.in, Ramakrishna detailed the discoveries his team made in Keezhadi and expressed hope that the new team would make even more important discoveries. Excerpts:

When and how did you identify the Keezhadi site?
In 2013-’14, a four-member team headed by me surveyed the Vaigai river banks from its starting points near the Velli Malai in the Western Ghats to Aatrankarai near the sea. We explored up to a radius of 8 km on either side. The total river length is about 250 km and it flows through five districts in Tamil Nadu.

It [the survey] involved exploring close to 500 villages. We discovered a variety of archaeological evidences in 293 locations and many of them were potential habitation sites. A variety of burial sites were also found. We identified many loose sculptures and hero stones and elaborate inscriptions and even temple sites.

So all 293 locations were settlements? How crucial was this discovery?
Among the 293, we filtered down to about 90 habitation sites. The importance of this discovery was huge. All this while, the theory was that there were no proper ancient habitation sites or riverine settlements in Tamil Nadu. All that was found till we identified these sites were primarily burial sites. In fact, the very reason to pursue this excavation was to disprove such false theories. We wanted to embark on the first large-scale river basin archaeological excavation in Tamil Nadu.

Excavations sites like Arikamedu [near Puducherry] and Kaveripoompatinam [near Nagapattinam] did not give us the kind of results we expected to authoritatively establish the existence of urban settlements. Adichanallur, which was excavated in 2005, turned out to be only a burial site after showing early potential.

We analysed the evidences we got from over 90 of these sites which showed signs of habitation and decided to focus on Keezhadi. Here, we found well-preserved burnt bricks. The situation was that bricks, a widely-recognised marker for urban settlements, were not found at all in Tamil Nadu. This changed in Keezhadi, which we picked as the best from three most promising sites. Other two were Siddharnatham, 40 km West of Madurai, and Maranadu which was 35 km Southeast of Madurai. It took a year to complete these surveys and select Keezhadi as our site for excavation.

How much was the Tamil Sangam literature an inspiration to these excavations?
The curious thing was, we have the great treasure of Tamil Sangam literature with its magnificent poetry. But there is no archealogical evidence to back the existence of the Sangams [ancient Tamil academies] mentioned in the literature. One reason is that there have not been serious excavations along the Vaigai river as it has remained a continuous settlement since the ancient times. Madurai, as you know, was the capital of this Sangam age. So logically, it is here that we should be looking for evidence of an ancient Tamil civilisation.

The fact that Madurai has had continuous settlements for centuries made it difficult to carry out excavations there. How was Keezhadi different?

Keezhadi site was almost intact, in the sense there were coconut groves that were older than 40 years. In those times, there was no disturbance to these sites as there was no development. In other areas closer to Madurai, many potential sites would have been destroyed as they dig for construction or to lay roads. Keezhadi did not have this problem as it was a naturally protected site.

How crucial was the fact that Keezhadi was being excavated by the ASI and not by any other organisation?
State archaeological departments lack the funds to conduct extensive excavations. The Bengaluru ASI office was started in 2001. We were tasked with excavations in South India. This was a great advantage as ASI has the financial provisions to exploit the site to its full potential.

Once you identified Keezhadi, how did you go about the excavations?
First, we measured the archaeological mound. The Mean Sea Level in that area is 119 metres. This mound was 123 metres. It had over 3.5 metres of sediment deposits. The circumference was 4.5 km. It is very rare to find this kind of a settlement in these areas.

We started the excavations in 2014-2015 in two localities. One was on the eastern side and other slightly near the river. When we began the excavations, we immediately started finding fine pottery. In a short time, we stumbled upon structures.

What were the most crucial findings of the first phase of excavations?
We found ring wells. Now this is a crucial finding which indicated that it was an urban settlement because it was in such settlements that people make wells. Essentially, wells make people’s life easy and saves time. They don’t have to go to the river or lake every time to fetch water. On a lighter vein, you can say wells are the innovation of human laziness.

But wells are also crucial for small-scale industrial activity. Then we found walls and platforms and large brick floors. There were flourishing antiquities, including ivory dayakattai (a Tamil dice game).

In the first phase in March to September 2015, we dug 43 trenches of 4 feet by 4 feet measurements. By this time, a lot of scholars started visiting.

Tell us about the second phase..
In the second phase in 2016, we did 59 trenches. In total, there were 102 trenches, the largest ever in Tamil Nadu. In the second phase, we found even better evidence of urban settlements like a complex drainage systems with terracotta pipes. We found bigger platforms made of bricks and six furnaces, indicating industrial activity.

What do these findings tell us? Is there a larger narrative here?
What all this did was it disproved the theory that there were no urban settlements in the Sangam era. The blame should be squarely placed on ourselves, because there were no attempts in the past to find concrete archaeological evidence. It was lying there but we did not explore it.

If we excavate the 90 other sites we found along the Vaigai river, I am sure we will find more settlements. They could be more ancient and perhaps more complex. I believe much of what is mentioned in the Sangam literature, of a great Madurai city that was the epicenter of a bustling civilisation, could be very much accurate and could present itself if we dig carefully.

How do you connect these to the Sangam age?
In all, we found 74 Tamil Brahmi inscriptions. They were similar to characters used in 200 BCE. Another significant thing was that these inscriptions were on potteries. Inscriptions commissioned by kings are found in stones and walls of temples. When you find inscriptions on pottery, it tells you a story. That story is that the common man was literate – another sign of a great settlement.

There were poetic Tamil names on those inscriptions, some of which you find in the Sangam literature. These people knew about the literature. By writing names on pottery, you sort of claim ownership. This is still in vogue.

But is this evidence enough to prove that a major civilisation existed?
If you look at the 130 BCE Kharavela inscriptions in Hathikhumba in Odisha, it tells us that there was a Tamil confederation at that time. There was a big kingdom down South with confederates, which Kharavela of Kalinga is said to have disbanded. This means there should have been a urban settlement, a civilisation and a kingdom in the South. Scholars in the North usually point to lack of archaeological evidence to deny these. After 70 years of independence, we got a chance to provide this evidence.

Is it right to make comparisons between the Vaigai settlements and the Indus Valley civilisation?
Vaigai river civilisation was as complex as the Indus Valley or Gangetic civilisations. We completed two seasons of excavations. I cannot say it is older than Indus Valley and Gangetic civilisation since dating of the site is not complete. We have done only till four metres and that too on only one site. The site goes deeper, even up to 6.5 metres.

Also, only the eastern and central sides of Keezhadi have been analysed. The northern and western sides remain. This is a great moment for all of us as these excavations could throw light on the rich past of this extraordinary region.

Were you disappointed that you were transferred in the middle of such a crucial project?
For the third season, I made the proposal. I was given the approval as well. Funds were allotted in March after a delay, claiming status report needed to be filed. But unfortunately, I have been transferred in the middle of this crucial excavation. While I am disappointed, I wish the new team takes forward the excavations and we find even better and older evidence.

Putting the patient first - insights for hospitals to meet customer service expectations

These emerging solutions are a fine balance between technology and the human touch.

As customers become more vocal and assertive of their needs, their expectations are changing across industries. Consequently, customer service has gone from being a hygiene factor to actively influencing the customer’s choice of product or service. This trend is also being seen in the healthcare segment. Today good healthcare service is no longer defined by just qualified doctors and the quality of medical treatment offered. The overall ambience, convenience, hospitality and the warmth and friendliness of staff is becoming a crucial way for hospitals to differentiate themselves.

A study by the Deloitte Centre for Health Solutions in fact indicates that good patient experience is also excellent from a profitability point of view. The study, conducted in the US, analyzed the impact of hospital ratings by patients on overall margins and return on assets. It revealed that hospitals with high patient-reported experience scores have higher profitability. For instance, hospitals with ‘excellent’ consumer assessment scores between 2008 and 2014 had a net margin of 4.7 percent, on average, as compared to just 1.8 percent for hospitals with ‘low’ scores.

This clearly indicates that good customer service in hospitals boosts loyalty and goodwill as well as financial performance. Many healthcare service providers are thus putting their efforts behind: understanding constantly evolving customer expectations, solving long-standing problems in hospital management (such as long check-out times) and proactively offering a better experience by leveraging technology and human interface.

The evolving patient

Healthcare service customers, who comprise both the patient and his or her family and friends, are more exposed today to high standards of service across industries. As a result, hospitals are putting patient care right on top of their priorities. An example of this in action can be seen in the Sir Ganga Ram Hospital. In July 2015, the hospital launched a ‘Smart OPD’ system — an integrated mobile health system under which the entire medical ecosystem of the hospital was brought together on a digital app. Patients could use the app to book/reschedule doctor’s appointments and doctors could use it to access a patient’s medical history, write prescriptions and schedule appointments. To further aid the process, IT assistants were provided to help those uncomfortable with technology.

The need for such initiatives and the evolving nature of patient care were among the central themes of the recently concluded Abbott Hospital Leadership Summit. The speakers included pundits from marketing and customer relations along with leaders in the healthcare space.

Among them was the illustrious speaker Larry Hochman, a globally recognised name in customer service. According to Mr. Hochman, who has worked with British Airways and Air Miles, patients are rapidly evolving from passive recipients of treatment to active consumers who are evaluating their overall experience with a hospital on social media and creating a ‘word-of-mouth’ economy. He talks about this in the video below.

As the video says, with social media and other public platforms being available today to share experiences, hospitals need to ensure that every customer walks away with a good experience.

The promise gap

In his address, Mr. Hochman also spoke at length about the ‘promise gap’ — the difference between what a company promises to deliver and what it actually delivers. In the video given below, he explains the concept in detail. As the gap grows wider, the potential for customer dissatisfaction increases.

So how do hospitals differentiate themselves with this evolved set of customers? How do they ensure that the promise gap remains small? “You can create a unique value only through relationships, because that is something that is not manufactured. It is about people, it’s a human thing,” says Mr. Hochman in the video below.

As Mr. Hochman and others in the discussion panel point out, the key to delivering a good customer experience is to instil a culture of empathy and hospitality across the organisation. Whether it is small things like smiling at patients, educating them at every step about their illness or listening to them to understand their fears, every action needs to be geared towards making the customer feel that they made the correct decision by getting treated at that hospital. This is also why, Dr. Nandkumar Jairam, Chairman and Group Medical Director, Columbia Asia, talked about the need for hospitals to train and hire people with soft skills and qualities such as empathy and the ability to listen.

Striking the balance

Bridging the promise gap also involves a balance between technology and the human touch. Dr. Robert Pearl, Executive Director and CEO of The Permanente Medical Group, who also spoke at the event, wrote about the example of Dr. Devi Shetty’s Narayana Health Hospitals. He writes that their team of surgeons typically performs about 900 procedures a month which is equivalent to what most U.S. university hospitals do in a year. The hospitals employ cutting edge technology and other simple innovations to improve efficiency and patient care.

The insights gained from Narayana’s model show that while technology increases efficiency of processes, what really makes a difference to customers are the human touch-points. As Mr. Hochman says, “Human touch points matter more because there are less and less of them today and are therefore crucial to the whole customer experience.”

By putting customers at the core of their thinking, many hospitals have been able to apply innovative solutions to solve age old problems. For example, Max Healthcare, introduced paramedics on motorcycles to circumvent heavy traffic and respond faster to critical emergencies. While ambulances reach 30 minutes after a call, the motorcycles reach in just 17 minutes. In the first three months, two lives were saved because of this customer-centric innovation.

Hospitals are also looking at data and consumer research to identify consumer pain points. Rajit Mehta, the MD and CEO of Max Healthcare Institute, who was a panelist at the summit, spoke of the importance of data to understand patient needs. His organisation used consumer research to identify three critical areas that needed work - discharge and admission processes for IPD patients and wait-time for OPD patients. To improve wait-time, they incentivised people to book appointments online. They also installed digital kiosks where customers could punch in their details to get an appointment quickly.

These were just some of the insights on healthcare management gleaned from the Hospital Leadership Summit hosted by Abbott. In over 150 countries, Abbott is working with hospitals and healthcare professionals to improve the quality of health services.
