Iranian folklore, including jokes, legends, games, folklore heroes and beliefs is sophisticated and complex.
"Dāstān" in Persian means “story". The genre to which they refer may go back to ancient Iran.It was a widely popular and folkloric form of story-telling: dastan-tellers tend to tell their tile in coffee houses.They told tales of heroic romance and adventure,stories about gallant princes and their encounters with evil kings, enemy champions, demons, magicians,Jinns, divine creatures, tricky Robin Hood-like persons (called ayyārs), and beautiful princesses who might be human or of the Peri (“fairy”) race.
Poker is virtually indistinguishable from an older Persian game called as nas, a four-hand game played with a 20-card pack, five cards dealt to each player. This coincidence led some students of games to call poker a derivative of as nas, but this theory has been discredited.
