So a historian and his friend were walking through a garden full of flowers. The soil was alluvial in nature. It never seemed that the place was inhabited by humans for more than 5 millennia. Probably the Persians had invaded the site even before the birth of Jesus Christ only to be conquered by Alexander the Great some hundred years later. Oh, by the way, legend has it that Jesus Christ was visited by three wise men from Persia - Balthasar, Melchior, Caspar - the priests of Zarathustra religion, the mages.
"Who wouldn't want it - look at the beauty of this place" - exclaimed the friend of the historian to which he replied - "Its the land of 5 rivers you are talking about. With the fertile plains streching far and wide, it did leave a lot of conquerors with their mouth open. In fact the Persians had invaded it at around 522 BC but it is debatable if they had come earlier than that". Before he could narrate the complete history, he spotted something shiny silvery and round. It was a coin. He quickly dusted it. At first glance, it did look like an ancient coin - possibly minted by the Persians themselves. Upon having a closer look, he found that it had an inscription which he deciphered as 556 BC and told his friend about his new found joy. Seeing the term BC, He figured out it must have been the year in which the coin was minted. Well wait, how could that even be possible ?? The Persians did not use the English language although Persians did have a language of Indo European origin. "I am sure it meant something else" - said his friend after thinking a bit. "How can you be so sure? This coin could be the key to concluding that the Persians had arrived here earlier than expected", he asked with curiosity to which the friend replied "Let us say that Persians knew English very well....... and then use your brain to figure the rest".
Hey readers, what is your opinion ? Do you think the friend of the historian was bluffing ? Or does he know something that we and the historian don't ? Can you figure it out? Comment on the authenticity of the coin. Lets us see how the debate goes... Or would it be a one liner ?
