Demons in Ancient Iranian Literature

Iran Chamber Society: A Mythological Glance at Demons in Ancient Iranian Literature The Book of Kings (Shahnameh) has it that during the rule of the legendary king of Persian, Jamshid, demons worked as engineers and architects to build bathhouses, bridges and houses. As one can understand from Firdawsi's poems, demons were like humans or those with different, heretical religious beliefs. Probably they were polytheists and had remained faithful to the religion of their ancestors. Therefore, they were probably people who were backward in terms of civilization. They were hunters who lived in caves or were nomads and spent most of their lives in the mountains. Can't we take caves as symbol of black tents at those times?
