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).
Nagavarma I
Nagavarma I (c. 990) was a noted Jain writer and poet in the Kannada language in the late 10th century. His two important works, both of which are available are, "Karnataka Kadambari", a "champu" (mixed prose-verse metre) based romance novel and an adaptation of Bana's Sanskrit "Kadambari", and "Chandombudhi" (also spelt "Chhandombudhi", "lit", "Ocean of prosody" or "Ocean of metres"), the earliest available work on prosody (study of poetic metres) in the language which Nagavarma I claims would command the respect even of poet Kalidasa. According to the scholars K.A. Nilakanta Shastri and R. Narasimhacharya, Nagavarma I belonged to a migrant Brahmin family originally from Vengi (in modern Andhra Pradesh). According to the modern Kannada poet and scholar Govinda Pai, Nagavarma I lived from 950 AD to 1015 AD. So popular was Nagavarma I's poetic skills that King Bhoja of Malwa (central India) presented him with horses, in appreciation of his poetic skills.
