Mehragan Celebration, which is the second most ancient celebration of Iranians after Norouz, starts on the 10th of Mehr (the seventh month of the Iranian calendar) and lasts for six days. Ancient Iranians believed that on this day, Kaveh the blacksmith rebelled against the tyrant Zahhak, and with the help of Fereydun, he overthrew him. Since the second millennium BC, the Iranian people have celebrated this day. Zoroastrians in Meybod hold the Mehragan ceremony in the village of Mazrae Kalantar or Chak Chak. During the Mehragan celebration, they spread out a Mehragan table. The table, which is purple, is spread on a fire pit, and various fruits, sweets, and foods are placed on it. They also prepare a special mix of seven kinds of dried nuts, including walnuts, almonds, pistachios, hazelnuts, chickpeas, dried mulberries, and figs. Another food item on the table is a dish called "Seven-Grain", which is a combination of wheat, rice, barley, chickpeas, lentils, mung beans, and raisins. They also put a bowl of rosewater, water, vinegar, rosemary leaves, purple flowers, and basil leaves on the table.
