Iranian archeologists plan to launch a new stage of studies aimed at finding out the dominant lifestyle of people who used to live during the 3rd millennium BC in the Iranian famed Burnt City, southeastern of the country.

The new round, starting on Oct. 6, would last one month and would be headed by Mansour Sajadi, Iranian archeologist who is right now abroad but would return for the project.

“We are now awaiting Sajadi so we could start the study as soon as possible. Our study would focus on anthropological issues in the Burnt City,” noted Mohammad Forozanfar, an anthropologist with the project.

Signs of civilization, first laid down in the Burnt City in 3200 B.C., remained intact up to 2100-2000 B.C. and during four successive periods in history. One of the prominent relics found in the Burnt City is a skull believed to be the first evidence of brain surgeries in prehistoric Persia.

Experts had earlier estimated a thorough identification and documentation of an astounding 4 billion artifacts in the Burnt City would require some 400 years, at least. Archeologists have already managed to document and profile 102 villages of the sprawling city, located south of Zabol in the eastern province of Sistan-Baluchistan.
