Like all stories this was interesting listening to but was wrong on facts.
According to the temple authorities this statue was made during the reign of 'King Paetiss the second'. This was in the Buddhist Era 237 (307 BC). The statue is 42 feet and four inches in height, being four inches higher than the 'Aukana statue'. Thus it was claimed that it was more than 400 years older and was four inches higher than the majestic 'Aukana' statue.
The statue shows signs of not having been completed.
