In the mean time these magicians appear to have produced the wonderful effects which drew to them the reverence of the vulgar, very frequently by the intervention of certain beings of a nature superior to the human, who should seem, though ordinarily invisible, to have had the faculty of rendering themselves visible when they thought proper, and assuming what shape they pleased. These are principally known by the names of Peris, Dives, [146] and Gins, or Genii. Richardson, in the preface to his Persian Dictionary, from which our account will principally be taken, refers us to what he calls a romance, but from which he, appears to derive the outline of his Persian mythology. In this romance Kahraman, a mortal, is introduced in conversation with Simurgh, a creature partaking of the nature of a bird and a griffon, who reveals to him the secrets of the past history of the earth. She tells him that she has lived to see the world seven times peopled with inhabitants of so many different natures, and seven times depopulated, the former inhabitants having been so often removed, and giving place to their successors. The beings who occupied the earth previously to man, were distinguished into the Peris and the Dives; and, when they no longer possessed the earth in chief, they were, as it should seem, still permitted, in an airy and unsubstantial form, and for the most part invisibly, to interfere in the affairs of the human race. These beings ruled the earth during seventy-two generations. The last monarch, named Jan bin Jan, conducted himself so ill, that God sent the angel Haris to chastise him. Haris however became intoxicated with power, and employed his prerogative in the most reprehensible manner. God therefore at length created Adam, the first of men, crowning him with glory and honour, and giving him dominion over all other earthly beings. He commanded the angels to obey him; but Haris refused, and the Dives followed his example. The rebels were for the most part sent to hell for their contumacy; but a part of the Dives, whose disobedience had been less flagrant, were reserved, and allowed for a certain term to walk the earth, and by their temptations to put the virtue and constancy of man to trial. Henceforth the human race was secretly surrounded by invisible beings of two species, the Peris, who were friendly to man, and the Dives, who exercised their ingenuity in involving them in error and guilt. The Peris were beautiful and benevolent, but imperfect and offending beings; they are supposed to have borne a considerable resemblance to the Fairies of the western world. The Dives were hideous in form, and of a malignant disposition. The Peris subsist wholly on perfumes, which the Dives, being of a grosser nature, hold in abhorrence. This mythology is said to have been unknown in Arabia till long after Mahomet: the only invisible beings we read of in their early traditions are the Gins, which term,
