During the field works in Jaffna

Well, I reckoned it will be good to put some thoughts came to me while working in the Jaffna-Kantarodai research session, 2019. I left Sydney on 5th February, by AirAsia to Sri Lanka, it took another seven hours journey to reach Jaffna by Uttaradevi train. A nice cosy place near to Maruthanamadam Anjaneyar Kovil will be our dwelling for the next few days, until we are returning to the previous one, which was other members of the team stayed since 25th January.

The trenches at the mound are ongoing with some fruitful results. However, it is not a place to mention such. Throughout the survey, some things caught my attention and without keeping them as photographs, why shouldn't I post it here and create a longlasting journal entry?

From systemic context to archaeological context. This pile of bottles from various sodas to alcohol piled around a small termite mound will eventually become an archaeological value if it buried underneath the soil and passed the passage of time for few more years. Yet it is now in the archaeological context, it going in-between of systemic context too. Following is another example. 
These two athiliya and hattiya type potteries are discarded into a scatter of garbage. How long will they preserve in the present condition, and what they can pass to the future about the context they were in use?

Wells of walls covered with limestone or coral bricks are unique to the Jaffna peninsula, and almost all the houses do have a well. In some instances, the well was used for generations, while the settlers are moved very recently and built a new dwelling in a place where there was an old, sometimes wattle and daub houses. Some wells may be redone and altered. Is that the depth, size and the materials can make any classificatory interpretations of these wells?

This is another well with a cement guard wall. The peculiar feature is the limestone step below the wall which has two carved edges at both sides. The way the cut was done and the size of the pillar do not matching with the other recent features in the surrounding, and I could not swallow the fact that dwellers told about it as they purchased it from a stone pillar manufacturer! It seems to be one of the last things you are going to spend on when you are working hard to build a new house. Anyhow, it seems a bit archaic to me.

Sometime back, the farmers let their straw to deteriorate and absorb to their paddy fields. Nowadays, these massive piles of straw transporting to distance and what it takes away is the fertility of the soil. Every single drop of these will lead to?


Mayakkai, a limestone cave formation in Jaffna peninsula can be one of the possible early human habitations in the region. Above is a panoramic view of the location and the caves filled with soil are located in the left corner. The terrain is flat, and the slope is toward the caves which causing the flooding and submergence of the caves during the rainy seasons. The present note especially for a folk story which was told by Prof Krishnaraja while we are looking at the location.

"The name Mayakkai derived from an early term referred to the caves 'Mayakkuhai' or the 'caves of magic (or Maya). It said the flat terrain in front of the caves was a paddy field at one point of the time. Farmers experience that their paddy was eating by a herd of cows but was unable to locate the whereabouts these cows are coming. One day, one of the farmers stayed alert all night, and he saw a herd of cows are coming through the cave and started to eat paddy. When the animal left before the dawn, he tried to stop on of cows by pulling its tail, but the animal managed to escape by pulling the man with it into the cave. The farmer saw a bright light inside of the cave, and when he walked towards, it was some unusual group of people who are doing sort of ritual and spoke a different language. When they found the farmer was watching them, they cursed him not to say anything to anyone what he saw in the cave, and if he does so, he will die at the very moment. Afraid to death, the man was able to keep his promise until one point, but at one day he breached it. He told his wife about the cave and all that he saw and died. Since then people started to call the caves as 'Mayakkuhai'...


The rock on the top of the granite stone is limestone. The informant who we spoke with named it as Katti kallu or forest stone they bought from Milankadu stone quarry. The origin of these names can be something worth to study.

 
The houses made with sunburnt bricks are something unusual to see in the area. In the above case, it seems the brick is made with a mixture of soil and grit but not clay. The bricks are highly loose and were exposed to the rain and wind, most of the bricks are decayed while the cement bond remains intact. When talking about the building materials can we outline some phases that people were able to afford stronger materials as rocks and some periods they relied on wattle and daub? Such an attempt will be usefull when talking about the settlement history and the economy of the region.

මනෝ සංවාද

දීර්ඝ කාලයක් පුරාවට මම මා සමග ම මනෝ සංවාදයේ  යෙදෙමින් ගෙනගිය කතිකාවත කොතැනක හෝ සටහන් කළ යුතුයැයි අදහසක් පැවතියත් දිනපොත ලිවීම නතරවූ තැන් සිට සුදුසු තැනක් පිළිබද අදහසක් අැති  නොවීය. මෙම මනෝ සංවාද සටහන ඒවැනි මාගේ හුදු අදහස් පිටකර නිදහස් වීමට සුදුසු තැනක් ලෙස පවත්වාගන්නට අදහස් කලේ ඒබැවිනි. ගැටලු ලෙසින් ලියාතැබීම සුදුස්යැයි හැගී ගියේ මේ සදහා මා  වෙත පිළිතුරු නැති බැවිනි.

1. අනාගත ලෝකය විශ්වයේ කාල-අවකාශ සීමාව ජයගනු අැතැයි මා හට සැක සහිතය. මිනිසා පෘථීවියෙන් පිටත් ව වෙනත් ලෝකයක මානව ජනාවාස තනනු අැතැයි යන සුබවාදී සිහිනය හෝ බලාපොරොත්තුව මානව සංහතිය තුල අැති කිරිමේ අවශ්‍යතාවය කුමක් ද? ජීවත් වීමට අාහාර හෝ ජලය යදින මිලියන ගණනක් සිටින අතර ම ඔවුන් මරණය වෙත යෑමට ඉඩ දී අභ්‍යාවකාශ තරණයේ පර්යේෂණ සදහා ධනය වැය කරන්නේ අැයි? මූලික ලෙස ම ලෝකය තවත් හැකි තරම් කාලයක් පවත්වා ගැනීමේ අපේක්ෂාවෙන් විය යුතු ය. මානව සංහතිය මෙම පෘථිවිය තුළ දීර්ඝකාලීනව පවත්වාගැනීමට නම් ජනගහණයේ යම් සීමාවීමක් විය යුතු අතර ම ජීවත්වන්නවුන්ට යම් අරමුණක් ද අවශ්‍ය  වේ. නූතන විද්‍යාවේ යම් යම් අංශ සේවය කරනුයේ මෙම රීතියට ද?

I was highly fascinated by founding that Dan Brown's Inferno is questioning a matter much similar to my original question. If someone or a group of people believes in this anti-population concept to reduce the pressure made by humans on the earth, it can be a well established longterm mission which will be not apparently visible to the majority of the people. Though we are 'declining' the truth, the glorious future might stand on the bone and blood of billions of victims not just from human but animal and plant kingdoms too. Anyhow, mother nature should have something in her agenda for us while we are thinking in our own regulated evolution.

A journey to the Van Diemen's Land

Well, Australia is full with natural wonders you can see everywhere and a hidden cultural heritage of Aborigines. The journeys made during the last three years in this land mass provided a great insight to us about the geological and cultural history of a land filled with its own unique stories. This little note is about the Van Diemen's land or as most commonly called 'Tasmania'.

The total credit of the journey, its planning and itinerary must go to Pramuditha. She put numbers of hours for tour homework, was able to provide us with a pleasurable memory. First, we planned to get the ferry from Melbourne to Devenport. With all the Christmas vacation, the tickets of the ferry were soon sold out. Hence we had to have a plan B, that is getting a flight. Sydney to Hobart flight cost is somewhat $2000 for three of us. So as the plan C, we drive to the Melbourne and took Jetstar flight from there for $800 and rented a car from Bargain cars at Hobart Airport.

Parking in Melbourne is also cost a large sum. Pramuditha was able to find an Airbnb place which they allow us to park our vehicle at their home, drop us to the airport and pick up again as well as rooms for a stay which all costs only $105. Ethel and her husband must appreciate for their kind support as well as their entrepreneur attempt on such matters.

We left Sydney on 24th December 2018 around 9.30pm and booked a place at Goulburn for the overnight stay. Fortunately the owner of the house not available at that night as we checked in late midnight. Though the place was not that clean, we were able to manage everything and left Goulburn around 6.00 am. No need to mention the trouble I came with a manual air pump which inflated the tyres to 64pi!!. On the way, a Coles Shell filling station had a digital meter for a reveal.

Driving from Goulburn to Melbourne done in two stops. First stop was Holbrook, a small town in Hume Highway which is famous for its HMAS Otway submarine. Little nap for me and play time for Thumula re-energised us. After 63 km we stopped for filling at Albury and continued the journey for another 315km to reach Melbourne at 1.30 pm. The flight was at 4.00 pm from Domestic departure terminal 4, flight JQ 711 Jetstar. We are on board, yet Thumula was asleep. He missed the view.

Landed Hobart around 5.00 pm we faced several problems. Pramuditha paid a cafe by using her ANZ card and asked me about her Commonwealth debit card which I might use for getting a cart at the Melbourne airport. It seems I've lost it. Oh dear. It took us a while to call the bank and cancel the card then proceed to the bag collection point. No bags and no one to ask!! Finally, as we could locate they are in the arrival desk of Jetstar. Finally, we went to the Bargain cars information desk, and the lady in the reception asked us to deposit another $500 as a security deposit other than the paid $800. My debit card was drained, and Pramuditha's one lost we were in chaos. Then we had to get a premium cover of $150, which hopefully happened for good. Here we are with all our baggage and car ready, looking forward to the endeavour.

Stayed at Father Shammi's church with Nilusha and her family who came in the morning of the same day. The Bishop's house is a nice cosy place with two separate guests rooms with attached bathrooms and a shared kitchen. Fortunately, we bought some rice and cooking essentials for prepare the meals of the day as not a single shop was open in the Christmas Eve. All of us had a nice dinner anyway. Thumula had a nice play time too.

Next day to the Museum. The actual plan was to watch Unzoo: the Tasmanian Devil zoo, but at the last moment, we changed the plan while Nilusha's family headed to Taranna. Museum filled with lots of informative galleries including the Aboriginal shell industries and Thylacine gallery. It is a shame how the Thylacine or so-called Tasmanian Tiger were hunted down to its extinction. At the time 1 pound was paid for one killed adult tiger and 10cents per a juvenile. Recently, they announced the Tasmanian state is ready to give a price of $1.5 million for anyone who can report a tiger, which some belief lives in further inland of the forest reservoir. Yes, indeed the human race is cancer infected the earth. Am I not a single cell!!

Headed to Taranna to find Nilusha and others was not a success as no phone reception available there. We managed to reach Eaglehawk Neck at 2.35 pm, five minutes late to the actual departure time for the boat ride. Finally, we found our colleagues from there and fortunately it was only us to the trip. Damian was helpful, and knowledgeable gentlemen who work for marine conservation and working part with Sea Shepherds gave us one of the most delightful experience we ever had. The coastal rock formations, waterfall, dolphins, seals and albatross in a 30 km round trip was an extraordinary tour. I was able to manage my motion sickness and fortunately, Damian did not leave boat stopped for a more extended period. At the arrival back to the deck had some snacks and, 'Doo-Lishus' a mobile cafe had a nice 'Monte-Carlo' couldn't refuse to my self. Their berry range from strawberry, raspberry, boysenberry and blackberry ice cream and yoghurt

The third and the last destination was Port Arthur, which we behind the time when we visit. Anyway, by looking all the site in minutes, the reception let us in for a discounted rate. The total settlement stands for the memories of convicts, military and English rule over the land. The silent prison yet makes an echo through the mind. The level of conservation and the site presentation must be appreciated.

Following day, we headed to the Lake St Clair, 200m deep, the deepest lake in Australia. Though it recalls us the extensive Sri Lankan irrigation works, the unique rock formations of basalt, quartz, dolerite and sandstones polished and bolded by the lake waves creates something attractive to the visitors. Collected basalt rock piece contains air bubble marks as a result of a volcanic lava formation. There must be some other exciting formations in the region, but as we are running out of time, we had to leave St Clair and drive to Cradle Hills. It was a 200km drive through historical Queenstown, a mining settlement for gold and copper. Though the speed limit is 100km/h, the zigzag road won't allow speeding ahead of 60kmh. Lucky we were able to notice our first encounter with an Echidna in it's natural to environ.

Cradle mountain was also able to recall us the Horton Plains in Sri Lanka with its cloud rainforest and grasslands. The Dove lake creates a unique view with mountain background. Though we did not complete a track, the time spent at the Dove lake with Nilusha's family definitely a good memory for Thumula and Pramuditha. We had to adieu them from that point onwards. They had to drive back to Hobart and left Tasmania the next morning while we continued our journey to Launceston.

Not to mention the mess I come up by ordering food from an Indian restaurant, which ended us with two curry boxes and one rice box, our stay at Launceston was also a good time. The Cataract Gorge scenic chairlift and Platypus-echidna-sea horse encounter at Beuty Point added new knowledge and insight. Then to Lavender farm at Nabowla and to Weymouth fossil bay. The Fossil bay was mentioned as contains some crystalised wood, which we are not that much familiar with. So we had to collect some arbitrary specimens. Then another three-hour drive to Scamander through a zigzag road in midnight while wild animals roaming around. That is one of the best animal encounters we ever had. Hundreds of possums, wallabies and quolls are running all over the road, where we had to keep the car at its minimum speed to avoid a single hit. Gratefully, we were able to manage the whole trip without a single animal death, other than small bugs which I am feeling sorry about. At the end of the journey, the front rego plate was covered with tiny bugs corpses.

Spend the night at Blue Seas holiday villas, Scamander, a beachfront hotel located next to the estuary of Scamander river.

Land Snails in Archaeology



     Palaeoenvironmental reconstructions can do by using various evidence, and pollens are the most using micro remain. Pollens can retrieve from environments such as waterlogged or peat bog contexts. However, in the context which basicity is higher, pollen can be rare evidence while remains of snails can preserve in good condition. Analysing land snails provides an insight into the palaeoenvironments, but unlike the pollens, it is usually slightly smaller and more local scale.
Image result for land snails in archaeology
According to Michael Allan, the early pioneers of the land snail analysis in archaeology were conchologist Alfred Santer Kennard and BB Woodward. Though they did report shells that found from archaeological contexts and examined its usage on rainfall, moisture and humidity reconstructions, the vegetation cover vs land use pattern studies were not subjected to their consideration. Then, BW Sparks and Michael Kerney introduced the usage of land snails to study the significant climatic changes occurred between and within the glacial and interglacial environments. Finally, in 1972, John Evans published a seminal publication titled 'Land snails in archaeology', opened a new sub-discipline in archaeology. 

Some principals

Lands snails provide representative evidence of vegetation structure and indicate

  •  the quantity of shade
  • ground moisture or cover
  • presence of woodland
  • openness
  • the occurrence of leaf litter
  • etc....
While pollens show the presence of individual species, land snails provide an insight into the overall vegetation structure. 
When analysing the lands snails, the following basics should have a concern (adapted from Allen, 2017,9),


  • Shells of land snails are made with calcium carbonate and aragonite.
  • The chemical content of the shells allows them to preserve and survive in calcareous deposits.
  • If excavated vigilantly, shells can retrieve without broke.
  • Shells often can be seen by the naked eye or using a microscopic sorting
  • The shells can be counted for NISP and identifications can be made to taxa and often to species level. 
  • Analogical thinking!. Shells from archaeological sites often considered as belonged to the animals lived in the same environmental conditions as their modern counterparts. 
  • Every single species has their own preference for food, habitat and environment. 
  • Examing all the shell species from a context as a single unit may provide a proper insight to reconstruct the palaeo-ecology.
  • Ecology of a species can represent a micro-environment and the nature of vegetation. This relates to the past local environment and land use.
  • When processed in a sequence, the samples will show a profile of local land use history.
  • When samples collected from several sites from a single area and analyses, it will provide a proper land use pattern within a local landscape.

Changes of the vegetation cover can be a long-term climatic change or an anthropogenic or both.

When we speak about molluscs, someone can say ''ok, snails move slow and who cares them''. Anyhow, no one should forget that on the other side of the family there are squids and octopus and may be the mighty Kraken, a legendary cephalopod sea monster.
