The Zoroastrian conversion of deva (deus) into devil does not alone represent the work of this odium theologicum. In the early hymns of India the appellation asuras is given to the gods. Asura means a spirit. But in the process of time asura, like dæmon, came to have a sinister meaning: the gods were called suras, the demons asuras, and these were said to contend together. But in Persia the asuras--demonised in India--retained their divinity, and gave the name ahura to the supreme deity, Ormuzd (Ahura-mazda). On the other hand, as Mr. Muir supposes, Varenya, applied to evil spirits of darkness in the Zendavesta, is cognate with Varuna (Heaven); and the Vedic Indra, king of the gods--the Sun--is named in the Zoroastrian religion as one of the chief councillors of that Prince of Darkness. But in every country conquered by a new religion, there will always be found some, as we have seen, who will hold on to the old deity under all his changed fortunes. These will be called 'bigots,' but still they will adhere to the ancient belief and practise the old rites. Sometimes even after they have had to yield to the popular terminology, and call the old god a devil, they will find some reason for continuing the transmitted forms. It is probable that to this cause was originally due the religions which have been developed into what is now termed Devil-worship. The distinct and avowed worship of the evil Power in preference to the good is a rather startling phenomenon when presented baldly; as, for example, in a prayer of the Madagascans to Nyang, author of evil, quoted by Dr. Réville:--'O Zamhor! to thee we offer no prayers. The good god needs no asking. But we must pray to Nyang. Nyang must be appeased. O Nyang, bad and strong spirit, let not the thunder roar over our heads! Tell the sea to keep within its bounds! Spare, O Nyang, the ripening fruit, and dry not up the blossoming rice! Let not our women bring forth children on the accursed days. Thou reignest, and this thou knowest, over the wicked; and great is their number, O Nyang. Torment not, then, any longer the good folk!' [17]
