Similar depictions are found in the paintings of Cave 17, but this time in direct relation to the worship of the Buddha. In Cave 17, a painting of the Buddha descending from the Trayastrimsa Heaven shows he being attended by many foreigners. Many foreigners in this painting are thus shown as listeners to the Buddhist Dharma. The ethnic diversity is depicted in the painting in the clothes (kaftans, Sasanian helmets, round caps), hairdos and skin colors. In the Visvantara Jataka of Cave 17, according to Brancaccio, the scene probably shows a servant from Central Asia holding a foreign metal ewer, while a dark-complexioned servant holds a cup to an amorous couple. In another painting in Cave 17, relating to the conversion of Nanda, a man possibly from northeast Africa appears as a servant. These representations show, states Brancaccio, that the artists were familiar with people of Sogdia, Central Asia, Persia and possibly East Africa. Another hypothesis is offered by Upadhya, who states that the artists who built Ajanta caves "very probably included foreigners".
