The cups markings are 40000 years old. An ibex carving dates to 4000years ago. I guess the horseman motif also dates around 4000 years ago if not earlier. Unfortunately there's no mention of its age. http://www.bradshawfoundation.com/middle_east/iran_rock_art/index.php
Painting dates are tough to certain :) .
MfA the dating of the motives from Susa are 4000 years old however the motive above is from Khomein and dated to 40000 years.
Palisto do you have any kind of link to this.
"In of Khomein, there are many thousands of rock art sites, some of which have been dated to approximately 4,000 years old." Thiscis from Dr Mohammad Naserifard.
If you honestly believe the horseman figure is 40000 years old you are insane.
I adjusted the wording and added two links.
