Zahhāk or Zahāk, also known as Zahhak is an evil figure in Persian mythology.
In this myth, which is mentioned in the Shahnameh book, when Zahhak reaches the kingdom, Ahriman kisses his two shoulders and two snakes come out of those two shoulders. After that, he realizes that he has no other choice and he has to feed those two snakes with human heads.
The demon helps him and every day he chooses a few people at random from the youth of the city and kills them and brings their heads to the Zahhak.
Mandatory hijab has been a law in Iran for years. These days, even the pressure on women has increased and women who don't observe the hijab even a little are arrested by the security police and have to go somewhere and promise not to wear those clothes anymore.
In this piece I have combined these two stories.
