IN PRAISE OF MY BEAUTIFUL ISLAND,
INFORMATION, PHOTOGRAPHS AND VIDEO.

THE 13th CENTURY VENETIAN TRAVELER MARCO POLO DESCRIBED THE ISLAND AS 'THE JADE PENDANT IN THE INDIAN OCEAN'. THE ABUNDANCE OF GEMSTONES, SPICES, RAIN FORESTS AND WILDLIFE; THE MAGNIFICENT BEACHES, ANCIENT RUINS AND A WRITTEN HISTORY OF OVER 2500 YEARS MAKE THIS ISLAND A TOURISTS' PARADISE.

THE RUINED CITIES OF ANURADHAPURA AND POLONNARUWA ILLUSTRATE THE GLORY OF THE ANCIENT KINGDOMS. THE GIGANTIC STUPAS AND BUDDHA STATUES ARE AMONG THE BIGGEST MAN MADE STRUCTURES OF THE WORLD. THE MASSIVE RESERVOIRS, BUILT BY ANCIENT KINGS TO IRRIGATE THOUSANDS OF ACRES OF LAND, ARE MARVELS OF HYDRO ENGINEERING. THERE ARE EIGHT UNESCO WORLD HERITAGE SITES IN SRI LANKA

THE ISLAND WAS KNOWN TO THE GREEKS AS 'TAPROBANE' AND TO THE ARABS AS 'SERENDIB'. EARLY MERCHANTS VISITED THE ISLAND IN SEARCH OF GEMSTONES AND SPICES, MAINLY CINNAMON AND PEPPER. COFFEE AND TEA PLANTATIONS WERE STARTED BY THE BRITISH COLONIAL RULERS. CEYLON TEA IS FAMOUS THE WORLD OVER.

TOURISM INDUSTRY IS A MAJOR MONEY SPINNER FOR THIS BEAUTIFUL ISLAND. THE VAST EXPANSE OF BEACHES, RAIN FORESTS AND NATIONAL PARKS WITH HERDS OF WILD ELEPHANTS, THE CENTRAL HIGHLANDS WITH LITHE WATER FALLS, BRING IN THE TOURISTS. THE ISLAND IS DOTTED WITH HUNDREDS OF HOTELS TO ACCOMMODATE THE TRAVELER. AN ISLAND OF 25,000 SQ; MILES HAS 103 RIVERS AND 25000 RESERVOIRS, MOSTLY MAN MADE. WITH VARYING CLIMATIC CONDITIONS THIS IS TRULY A 'SMALL MIRACLE'.

" THE ISLAND OF SRI LANKA IS A SMALL UNIVERSE, IT CONTAINS AS MANY VARIATIONS OF CULTURE, SCENERY AND CLIMATE AS SOME COUNTRIES A DOZEN TIMES ITS SIZE........I FIND IT HARD TO BELIEVE THAT THERE IS ANY COUNTRY WHICH SCORES SO HIGHLY IN ALL DEPARTMENTS - WHICH HAVE SO MANY ADVANTAGES AND SO FEW DISADVANTAGES. LOVELY BEACHES, BEAUTIFUL LANDSCAPES, IMPRESSIVE RUINS, A VIBRANT CULTURE AND CHARMING PEOPLE- NO WONDER SRI LANKA IS A SMALL MIRACLE ".***** Arthur C. Clark *****

SRI LANKA - THE DEDIGAMA ELEPHANT LAMP [12th CENTURY HYDRO STATICS ]



The elephant lamp of Dedigama, Kotawehwra, is a twelfth century A.D. creation, by an unknown craftsman, during the reign of King Prakramabahu the 5th. 

The hollow figure of an elephant made of brass stands in the center of a circular oil  lamp with several wicks. The right front leg of the elephant is raised a few millimeters, there is a hole on the bottom of that foot. Oil is poured into the hollow of  the elephant through this hole by removing the elephant, the circular base of the lamp is filled with oil and the elephant is placed in the center of the lamp.

When the wicks are lit and the lamp burns for  a few hours the level of the oil 
decreases, when the level goes below the hole on the bottom of the right foot the atmospheric pressure forces the oil, inside the elephant, to flow into the basin through the hole in the genital organ, thereby increasing the level of oil for the wicks to burn.

This ingenious creation, based on hydro static principles, is on display at the Dedigama Museum. It has been displayed at the London Museum on several occasions and depicts the scientific knowledge of the ancient craftsmen of Sri lanka.
