班勇写过一部对古代西域地区的佚名记述,是他根据其父班超和自己在西域地区的长期实地考察写成的。这部全长四千多字的著述,反映了东汉时期中国人对中亚、西亚和南欧地区经济状况、地理方位、风土人情的认识水平。它作为东汉官方档案资料一直保存到南朝刘宋时期。《后汉书·西域传》就是依据班勇的记述写成的。由此可见,这部著述在当时是具有很大影响的。但令人惋惜的是,随着岁月流逝其书名已湮泐无存。班勇进行写作和成书的确切时间,史书中没有明确记载,只有范晔的一句话提供了 Ban Yong wrote an anonymous account of the ancient Western Regions, which he wrote on the basis of his father's super-class and his own long-term field trips in the Western Regions. The 4,000-plus-word book reflects the Chinese people's understanding of the economic conditions, geographical location and customs in Central Asia, West Asia and Southern Europe during the Eastern Han Dynasty.
