Kālidāsa
The most popular theory is that Kalidasa flourished during the reign of Chandragupta II, and therefore lived around 4th-5th century CE. Several Western scholars have supported this theory, since the days of William Jones and A. B. Keith. Many Indian scholars, such as Vasudev Vishnu Mirashi and Ram Gupta, also place Kalidasa in this period. According to this theory, his career might have extended to the reign of Kumaragupta I (r. 414 – 455 CE), and possibly, to that of Skandagupta (r. 455 – 467 CE).
Bharavi
As with most Sanskrit poets, very few concrete details are available about Bharavi's life, and inferences must be made from references to him. His name, along with great poet and dramatist in the Sanskrit language Kālidāsa's name, is mentioned in a Chalukya stone inscription dated 634 C.E. found at Aihole, located in present day Karnataka. In another inscription, the king Durvinita of the Western Ganga Dynasty mentions having written a commentary on the fifteenth canto of Bharavi's Kirātārjunīya. The Western Ganga Dynasty ruled from about the middle of the fourth century, and Durvinita is usually believed to have lived in the later half of the sixth century.
