Rice Culture of Sri LankaM. P. Dhanapala
Sri LankaSri Lanka, is one of the smallest of the South Asian nations, 29 km southeast of India across the Palk Strait in the Indian Ocean. Sri Lanka was not the name by which the island was always known. The Greeks and Romans knew it as Taprobane, the Arabian sailors as Serendib, the early Europeans in Asia as Zeilan or Seilan,the Portuguese as Ceylao, and the British as Ceylon. The Island nation has also been referred to as "The Pearl of the Indian Ocean".

Pliny’s Taprobane:"a land 'banished by nature outside the world' and hence free of the vices (wickedness) that plague other countries"
In Taprobane:"nobody kept a slave, everybody got up at sunrise and nobody took a siesta (nap) in the middle of the day; their buildings were only of moderate height; the price of grain was never inflated; there were no law courts and no litigation ... [and] the king was elected by the people on the grounds of age and gentleness of disposition and as having no children, and if he afterwards had a child, he was deposed, to prevent the monarchy from becoming hereditary." James S. Romm. Ultima Thule and Beyond, 30:133
