The Ajanta Caves painting are a significant source of socio-economic information in ancient India, particularly in relation to the interactions of India with foreign cultures at the time most of the paintings were made, in the 5th century CE. According to Indian historian Haroon Khan Sherwani: "The paintings at Ajanta clearly demonstrate the cosmopolitan character of Buddhism, which opened its way to men of all races, Greek, Persian, Saka, Pahlava, Kushan and Huna". Depictions of foreigners abound: according to Spink, "Ajanta’s paintings are filled with such foreign types." They have sometimes been a source of misinterpretation as in the so-called "Persian Embassy Scene". These foreigners may reflect the Sassanian merchants, visitors and the flourishing trade routes of the day.
