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).
Kannada
Kannada works from earlier centuries mentioned in the Kavirajamarga are not yet traced. Some ancient texts now considered extinct but referenced in later centuries are "Prabhrita" (AD 650) by Syamakundacharya, "Chudamani" (Crest Jewel—AD 650) by Srivaradhadeva, also known as Tumbuluracharya, which is a work of 96,000 verse-measures and a commentary on logic ("Tatwartha-mahashastra"). Other sources date "Chudamani" to the 6th century or earlier. The "Karnateshwara Katha", a eulogy for King Pulakesi II, is said to have belonged to the 7th century; the "Gajastaka", a work on elephant management by King Shivamara II, belonged to the 8th century, and the "Chandraprabha-purana" by Sri Vijaya, a court poet of King Amoghavarsha I, is ascribed to the early 9th century. Tamil Buddhist commentators of the 10th century AD (in the commentary on "Nemrinatham", a Tamil grammatical work) make references that show that Kannada literature must have flourished as early as the AD 4th century.
