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).
Khandoba
Sontheimer suggests that the cult of Khandoba is at least older than 12th century, which can be determined by references in Jain and Lingayat texts and inscriptions. A 12th-century Jain author Brahmashiva claims that a Jain, who died in battle after a display of his valour, was later named as Mailara. By the 13th century, wide worship of Malhari or Mailara is observed by kings, Brahmins, simple folk and warriors. With the rise of Muslim empire, classical Hindu temples fell into ruin, giving rise to the folk religion such as of Khandoba. Chakradhara remarks, 'by the end of the Kali Yuga, temples of Vishnu and Shiva will be destroyed, but those of Mailara will stay'. A 1369 AD inscription at Inavolu near Warangal tells an account of Mallari different from Malhari Mahatmya — Shiva helped the epic hero Arjuna kill the demon Malla, thus acquiring the title of Mallari. Mailara was the family deity of Kakatiya dynasty (1083–1323 AD); a text from their rule records the self-torture rituals of Mailara-devotees and describes the deity. Throughout his development, Mailara is looked upon as a lower manifestation of Ishvara (God) by Lingayat and Maharashtrian bhakti saints.
