Alawala Caves
Piecing together an ancient tale
The discovery of the remains of two pre-historic humans and other artifacts
in a cave in Alawala, Gampaha has got a group of Archaeology students
and other specialists digging for more clues to our mysterious past
The shark tooth ornament seems too small and delicate to have survived
so many centuries unaltered. The two people who wore it lie beside it,
but on them time has taken a heavier toll. Their bones lie scattered in
the quiet cave, and are unearthed in pieces. Buried with them is the debris
of their lives. Potshards, bone tools, seeds and even the remains of the
animals they feasted on lie mingled in the dust.
For the team from the Postgraduate Institute of Archaeology (PGIAR),
University of Kelaniya, this cave near the Alawala village in the Gampaha
district is a treasure trove. The team members have about them the air
of detectives, who with patient and plodding work are unravelling mysteries
many thousands of years in the making. Around 52 students from the Masters’ programme
are working with specialists including, archeo-chemists, botanists, geologists
and biospealeologists, in an attempt to recreate the lives of these two
pre-historic humans, and their finds might challenge many of our conventional
ideas about how our ancient ancestors lived.

Senior lecturer Gamini Adikari has over two decades experience excavating
sites all over Sri Lanka. Ancient human osteology (the study of human
bones) is his passion. “In the Western Province in Sri Lanka, we
have found pre-historic remains in only two places,” he says, listing
the first site as Pahiyangala, where the remains of a pre-modern man who
lived over 37,000 years ago were found. So far, the finds at this site
include fragments of skull, some mandibles with teeth as well as loose
teeth. He believes that they belonged to pre-historic humans who lived
in 13,000 B.C.E.
The amount of wear and tear on the surfaces of the molars and the proportions
of the mandibles and skull fragments indicate that there were probably
two people buried here and that one of them was a young man and the other
was an older woman. The former was probably in his late twenties, while
the latter may have been about 40. Unusually, red ochre has been applied
not only to the outside but to the inside of the skull fragments, a clear
sign that the remains were part of some ritual.
Beside the skeletal remains are further traces of red ochre and other
minerals like graphite and mica. Tools made of bone and stone throw light
on the primitive technology employed by those hunter gatherers. Of the
bone tools, Mr. Adikari says, “They are very small, very lovely
and very sharp.” These tools were in all likelihood used in hunting
and then in skinning the animals they caught. Matching scrape marks on
the bones indicate that the tools were used to separate the meat and
marrow from the bones. These primitive tools came in handy as arrowheads,
while removing seeds from inside the nut, and even to make new implements. “

They clearly practised butchery in the caves,” says Mr. Adikari
saying almost all the animal remains belong to small edible mammals and
birds. The bones of giant squirrels and monkeys have been found, as have
vertebrae belonging to pythons and fish. The team wonders whether the
two ancient humans found their way down to the ocean, some 20 miles distant.
Also found in the cave were several varieties of snails and wild breadfruit
seeds. The latter, known locally as kakuna, may have been roasted before
being eaten, says Jayasanka Hettiarachchi, a research assistant from the
Botany Section of the National Museum. Remains of ancient hearths in the
cave support this theory. Furthermore, a rock boulder, 6 or 7 feet in
diameter is dotted with spitted holes, which appear to have been used
for grinding. As for the snails, holes drilled into their shells may have
been the method by which the humans extracted the tender meat, says Dr.
Wasantha Weliange, a biospealeogist with PGIAR who is an expert in animal
life in caves. These may have then been used as pendants once their unfortunate
inhabitants had been consumed.
These finds may yet prove to be only the tip of the iceberg. The excavation
is currently limited to 6 square metres and is still in its first phase.
As a result the team’s theories are yet to be proven in the laboratory.
Mr. Adikari emphasises that he has come to his conclusions based on comparisons
with other specimens that belong to that period and in consultation with
learned colleagues like Dr. Nimal Perera of the Department of Archaeology.

of Archaeology.)

Mr. Adikari himself is no stranger to cave excavations, having worked
in Sigiriya, Aligala, Pidurangala, Asmadela and the Warana cave complex.
Still it may be several months before the results of carbon dating, mature
thermal analysis and DNA testing confirm his hypothesis.
However, it is the shards of pottery found at the site that most intrigue
archeo-chemist Dr. Arjuna Thantilage, also of PGIAR. He explains that
little evidence remains to throw light on Sri Lanka’s transition
from Stone Age to Metal Age. Conventional belief is that the change was
abrupt, and the Iron Age began with an intruding megalithic culture from
India. Saying that “we understand the potential that these sites
have to recreate our cultural transformation,” Dr. Thantilage adds
that sites such as this where people used pottery and stone tools together
are key to understanding the transition. “We may have identified
a new cultural phase,” he says explaining that the Gampaha site
has the basic elements already in place. His research is outlined in a
published paper titled ‘Protohistoric Copper Metallurgy in Sri Lanka’.
Unfortunately this site itself has been disturbed. Villagers have at
various points used it as a shelter, and have later collected the bat
droppings that lay thick on the ground for fertilizer. Chief Incumbent
of the Pothgullen Rajamaha Viharaya, Veyangoda, Venerable Kamburawala
Vajira Thera who visits it often explains that the site is known locally
as ‘Pothgul Kanda’ or cave of books and may have been used
as a shelter cave by monks in times past. Two newer inscriptions, perhaps
a mere 2,900 years old, support the theory that the cave has had many
inhabitants over the years.
The first phase of the excavation is drawing to a close. The team hopes
to start again in mid-February, with the full support of the Institute’s
Director Prof. Nimal de Silva. Mr. Adikari says that he intends to send
his students out to study the surroundings, to identify if they can what
species of plants and animals remain in the area, and how the humans who
live there currently interact with their surroundings. Such steps help
ethnoarchaeologists “recreate the whole landscape”. For the
rest of us, they serve as windows into our often mysterious past, where
our distant ancestors walked through a very different world.
