Interestingly enough, you will find the details in the National Geographic of December 1978 (pp.730-, esp. p.736) which confirms that in those tablets the city of Iram is mentioned. The people of Eblus used to do business with the people of Iram. So here in 1973, comes confirmation of the fact that, after all, there really was an ancient city by that name, wherever it was. How did it find its way into the Qur'an, we might ask?
