These are two wall paintings done at the XVII century at the Hasht-Behesht Palace ("Palace of the 8 heavens"). Musicians at the right and dancers at the left.
Music and dancing makes a great Sunday.
The history of art was always told taking Europe and the centre with few references of other cultures. Now it has been changing to a global approach. Two good examples are the books Mirror of the World by Julian Bell, 2007, 496pp, and A World History of Art by John Fleming and Hugh Honour, 1982.
