valid. The Buddhist chroniclers may have decided not to mention these non-Buddhists, so as not to sideline Buddhism. Frauwallner and Gombrich also believe that Ashoka was directly responsible for the missions, since only a resourceful ruler could have sponsored such activities. The Sri Lankan chronicles, which belong to the Theravada school, exaggerate the role of the Theravadin monk Moggaliputta-Tissa in order to glorify their sect. Some historians argue that Buddhism became a major religion because of Ashoka's royal patronage. However, epigraphic evidence suggests that the spread of Buddhism in north-western India and Deccan region was less because of Ashoka's missions, and more because of merchants, traders, landowners and the artisan guilds who supported Buddhist establishments. Violence after conversion According to the Ashokavadana, Ashoka resorted to violence even after converting to Buddhism. For example: He slowly tortured Chandagirika to death in the "hell" prison. He ordered a massacre of 18,000 heretics for a misdeed of one. He launched a pogrom against the Jains, announcing a bounty on the head of any heretic; this resulted in the beheading of his own brother – Vitashoka. According to the Ashokavadana, a non-Buddhist in Pundravardhana drew a picture showing the Buddha bowing at the feet of the Nirgrantha leader Jnatiputra. The term nirgrantha ("free from bonds") was originally used for a pre-Jaina ascetic order, but later came to be used for Jaina monks. "Jnatiputra" is identified with Mahavira, 24th Tirthankara of Jainism. The legend states that on complaint from a Buddhist devotee, Ashoka issued an order to arrest the non-Buddhist artist, and subsequently, another order to kill all the Ajivikas in Pundravardhana. Around 18,000 followers of the Ajivika sect were executed as a result of this order. Sometime later, another Nirgrantha follower in Pataliputra drew a similar picture. Ashoka burnt him and his entire family alive in their house. He also announced an award of one dinara (gold coin) to anyone who brought him the head of a Nirgrantha heretic. According to Ashokavadana, as a result of this order, his own brother was mistaken for a heretic and killed by a cowherd. Ashoka realised his mistake, and withdrew the order. For several reasons, scholars say, these stories of persecutions of rival sects by Ashoka appear to be clear fabrications arising out of sectarian propaganda. Family Queens Various sources mention five consorts of Ashoka: Devi (or Vedisa-Mahadevi-Shakyakumari), Karuvaki, Asandhimitra (Pali: Asandhimitta), Padmavati, and Tishyarakshita (Pali: Tissarakkha).
