When did Kalidasa live?
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).
Jagannatha Dasa
For about a century after the death of Vadirajatirtha (1480–1600), a noted saint-poet, the Haridasa devotional cult which propagated the "Dvaita" philosophy of Madhvacharya through lucid Kannada devotional songs, seemed to wane. The movement however revived in the 18th century under the guidance of Vijaya Dasa, this time centered on the holy town of Mantralayam in modern Andhra Pradesh and a large area covering the Raichur district in modern Karnataka. The poetry written by these later day saints closely followed the style established by the 15th- and 16th-century saints of the Haridasa cadre. The Haridasa contribution to Hindu mysticism and the "Bhakti" literature overall is similar to the contributions of the Alvars and Nayanmars of modern Tamil Nadu and that of the devotional saint-poets of Maharashtra and Gujarat. According to the scholar H.S. Shiva Prakash, about 300 saint-poets from this cadre enriched Kannada literature during the 18th–19th centuries.
