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).
Shakuntala (play)
Shakuntala, also known as The Recognition of Shakuntala, The Sign of Shakuntala, and many other variants (Devanagari: अभिज्ञानशाकुन्तलम् – Abhijñānashākuntala), is a Sanskrit play by the ancient Indian poet Kālidāsa, dramatizing the story of Shakuntala told in the epic Mahabharata. It is considered to be the best of Kālidāsa's works. Its date is uncertain, but Kālidāsa is often placed in the period between the 1st century BCE and 4th century CE.
