The most elaborate report of the celebration of Sadeh after the Muslim conquest of Persia in 7th century AD comes from the 10th century AD during the reign of Mardavij of Ziyarid dynasty, the ruler of Isfahan. The Ziyarid dynasty did their best to maintain Persian traditions. Bonfires were set up on both sides of the Zayandeh River to remember the Sadeh custom. The fires were kept in specially built metal holders. Hundreds of birds were released while the fireworks were lighting the sky. There were fireworks, dancing and music with lavish feasts of roasted lamb, beef, chicken and other delicacies.
