Ashvaghosha was a renowned Buddhist philosopher and poet who lived in the 1st or 2nd century CE, contemporary with the Kushan emperor Kanishka. He is considered one of the earliest figures in Sanskrit drama. Archaeological expeditions led by German scholars at Turfan (Xinjiang, China) in the early 20th century discovered fragmented manuscripts, including parts of Ashvaghosha's plays like 'Sariputra Prakarana'. These discoveries provided crucial evidence for the early history of Sanskrit drama.
