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).
Kālidāsa
The earliest paleographical evidence of Kalidasa is found in a Sanskrit inscription dated c. 473 CE, found at Mandsaur's Sun temple, with some verses that appear to imitate Meghaduta Purva, 66; and the Ritusamhara V, 2-3, although Kalidasa is not named. His name, along with that of the poet Bharavi, is also mentioned in a stone inscription dated 634 C.E. found at Aihole, located in present-day Karnataka.
