Soon it became apparent that Bahram himself was now the subject of the conversation, and he knew, from the General’s darting glances, that he was going to be in for a lengthy interrogation. It was odd to be spoken of without knowing what was being said and Bahram was glad when Zadig turned to him at last and began to translate the General’s words into Hindusthani.

It was in the same language that Bahram answered – but Zadig was by no means a passive interpreter and since he was more knowledgeable than Bahram about many of the subjects that were of interest to Napoleon, the conversation was quickly triangulated. For much of the time Bahram was merely an uncomprehending spectator. It wasn’t until much later that he was to understand everything that was said – yet in retrospect he remembered it all, with perfect clarity, as though he and Zadig had been listening and speaking with the same ears and the same tongue.

Napoleon’s first set of questions, Bahram recalled, were of a personal nature and embarrassed Zadig a little: the scourge of Prussia had declared that he was forcibly impressed by Bahram’s appearance and could see in his face and beard, a resemblance to the Persians of antiquity. In his costume, however, he saw no such similarity, for it seemed to be of the Indian type. He was therefore curious to know what aspects of the civilization of ancient Persia had been preserved by the Parsis of the present day.

Bahram was well prepared for this question, having often had to deal with similar queries from his English friends. The General was right, he answered, his clothing was indeed mostly that of Hindusthan, except for two essential articles: his religion required every adherent, male and female, to wear, next to their skin, a girdle of seventy-two threads called a kasti, and a vestment known as a sadra – and Bahram was wearing both of these, under his outer garments, which were, as the General had rightly surmised, no different from those which any other man of his country and station would have worn upon such an occasion. This adaptation in outward appearance, accompanied by the preservation of an inner distinctiveness, could also be said to extend to other aspects of the life of his small community. Where it concerned matters of belief Parsis had clung faithfully to the old ways, making every effort to adhere to the teachings of the prophet Zarathustra; but in other respects they had borrowed freely from the customs and usages of their neighbours.

And what are the principle doctrines of the Prophet Zarathustra?

The religion is among the earliest of monotheistic creeds, Your Majesty. The God of its holy book, the Zend-Avesta, is Ahura Mazda, who is omniscient, omnipresent and omnipotent. At the time of Creation Ahura Mazda is said to have unleashed a great avalanche of light. One part of this aura submitted to the Creator and was merged into him; the other part turned away from the light and was banished by Ahura Mazda: this dark force came to be known as ‘angre-minyo’ or Ahriman – the devil, or Satan. Since then the forces of goodness and light have always worked for Ahura Mazda while the forces of darkness have worked against Him. The aim of every Zoroastrian is to embrace the good and to banish evil.
