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).
Asaga
Asaga was a 9th-century Digambara Jain poet who wrote in Sanskrit and Kannada language. He is most known for his extant work in Sanskrit, the "Vardhaman Charitra" (Life of Vardhamana). This epic poem which runs into eighteen cantos was written in 853 CE. It is the earliest available Sanskrit biography of the last tirthankara of Jainism, Mahavira. In all, he authored at least eight works in Sanskrit. In Kannada, none of his writings, including the "Karnataka Kumarasambhava Kavya" (an adaptation of Kalidas's epic poem "Kumārasambhava") that have been referenced by latter day poets (including Nagavarma II who seems to provide a few quotations from the epic poem in his "Kavyavalokana") have survived.
