other foreigners as well after the 1st century AD. Patanjali, a grammarian and commentator on Pāṇini, around 150 BC, describes in the Mahābhāsya, the invasion in two examples using the imperfect tense Sanskrit, denoting a recent or ongoing events: "Arunad Yavanah Sāketam" ("The Yavanas (Greeks) were besieging Saketa") "Arunad Yavano Madhyamikām" ("The Yavanas were besieging Madhyamika" (the "Middle country")). The Brahmanical text of the Yuga Purana describes events in the form of a prophecy, which may have been historical, relates the attack of the Indo-Greeks on the capital Pataliputra, a magnificent fortified city with 570 towers and 64 gates according to Megasthenes, and describes the ultimate destruction of the city's walls: Accounts of battles between the Greeks and the Shunga in Central India are also found in the Mālavikāgnimitram, a play by Kālidāsa which is thought to describe an encounter between a Greek cavalry squadron and Vasumitra, the grandson of Pushyamitra, during the latter's reign, by the Sindh River or the Kali Sindh River. According to the Yuga Purana, the Yavanas thereafter will retreat following internal conflicts: According to Mitchener, the Hathigumpha inscription indicates the presence of the Indo-Greeks led by a ruler listed as "ta" from Mathura during the 1st century BCE. Although, the name of the king has been omitted and undeciphered. The remaining syllables [ta] has been disputed. It has been argued by Tarn to be referencing the ruler Demetrius. However this interpretation is disputed by other historians like Narain, which point out the discrepancies in chronology and the fact Demetrius didn't ventured past Punjab. Instead most historians now theorize it to be the Indo-Greek ruler Menander I, or perhaps a later Yavana king from Mathura. But while this inscription may be interpreted as an indication that Demetrius I was the king who made conquests in Punjab, it is still true that he never issued any Indian-standard coins, only numerous coins with elephant symbolism, and the restoration of his name in Kharosthi on the Hathigumpha inscription: Di-Mi-Ta, has been doubted. The "Di" is a reconstruction, and it may be noted that the name of another Indo-Greek king, Amyntas, is spelt A-Mi-Ta in Kharosthi and may fit in. Therefore, Menander remains the likeliest candidate for any advance east of Punjab. Consolidation Menander is considered to have been probably the most successful Indo-Greek king, and the conqueror of the largest territory. The finds of his coins are the most
