His ministers advised him that as long as Buddhism remained the dominant faith, he would never be as famous as his ancestor Ashoka, who had commissioned 84,000 stupas.
He then proceeded to Shakala in the north-west, where he offered a prize of one hundred Roman denarii (coins) for every head of a Buddhist monk brought to him.
[17] Shariputrapariprichha, translated into Chinese between 317 and 420 CE also mentions this legend, but this particular version is more detailed, and describes eastern India (not Kashmir) as the center of Pushyamitra's anti-Buddhist campaign.
[17] The medieval-era Arya-Manjushri-Mula-Kalpa mentions a wicked and foolish king named Gomimukhya ("cattle-faced"), or Gomishanda ("Gomin, the bull"), who seized the territory from the east to Kashmir, destroying monasteries and killing monks.
[20] According to archaeologist John Marshall, there is evidence of some damage to Buddhist establishments at Takshashila around the time of Shunga rule.
He also theorized that the Sanchi stupa was vandalized in 2nd century BCE (that is, during Pushyamitra's reign), before being rebuilt on a larger scale.
[21] G. R. Sharma, who excavated the Buddhist ruins at Kaushambi, suggested that the destruction of the local monastery might have happened during the reign of Pushyamitra Shunga.
[24] The Ashokavadana states that Pushyamitra declared a reward for killing Buddhist monks in Shakala (present-day Sialkot), which was located near the Indo-Greek frontiers.
Étienne Lamotte points out that the Buddhist legends are not consistent about the location of Pushyamitra's anti-Buddhist campaign and his death.
[28] The Sri Lankan Buddhist text Mahavamsa suggests that several monasteries existed in present-day Bihar, Awadh and Malwa at the time Pushyamitra's contemporary Dutthagamani ruled in Lanka.
[23] The fact that the Ashokavadana mentions Pushyamitra as a Mauryan further erodes its historical credibility, and weakens the hypothesis that he persecuted Buddhists because he was a Brahmin.
[30] Romila Thapar writes that the lack of concrete archaeological evidence casts doubt on the claims of Buddhist persecution by Pushyamitra.
[25] Michael Witzel states that Manu Smriti, which emphasizes the role of orthodox faith in state-craft and society, was first compiled under Pushyamitra's rule.
