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).
Chandidas
Chandidas (; born 1408 CE) refers to a medieval poet of Bengal or possibly more than one. Over 1250 poems related to the love of Radha and Krishna in Bengali with the "bhanita" of Chandidas are found with three different sobriquets along with his name, "", "Dvija" and "Dina" as well as without any sobriquet also. It is not clear whether these "bhanita"s actually refer to the same person or not. It is assumed by some modern scholars that the poems which are current in the name of Chandidas are actually the works of at least four different Chandidas, who are distinguished from each other by their sobriquets found in the "bhanita"s. It is also assumed that the earliest of them was Ananta Chandidas, who has been more or less identified as a historical figure born in the 14th century in Birbhum district of the present-day West Bengal state and wrote the lyrical "Srikrishna Kirtan" (Songs in praise of Krishna).
