The goddess who rode the lion was well known in the Middle East and the Mediterranean region for millennia, as Ishtar in Mesopotamia, Astarte in Greece and Cybele in Troy.
When we look at Durga's image in her desperate battle against the ferocious Mahishasura, we may also notice that her family members appear rather disinterested. Handsome Kartik does not lift his weapons; Ganesh appears almost smiling; Lakshmi holds on to her jhampi more tightly and Saraswati looks pretty with her veena. To understand this strange situation, we have to turn to history, first from other countries and then closer at home.
The goddess who rode the lion was well known in the Middle East and the Mediterranean region for millennia, as Ishtar in Mesopotamia, Astarte in Greece and Cybele in Troy. Cybele was, in fact, so powerful that she was taken away to Rome in 204 BC from Turkeys' Anatolia and Roman emperors worshipped her as the "great mother of the gods", Magna Mater Deium. Till the 4th century, her temple was located where the holy Vatican stands now. It is quite interesting to note that her worship was known as “baptism in the blood of the sacred bull", as it is so close to Durga spilling the blood of the buffalo. She was also referred to as the “goddess of caves” which reminds us of Durga's origins from the words "inaccessible” or Durgam. According to Barbara Walker, "she personified the fighting spirit of a mother protecting her young". The Babylonian goddess Ishtar who rode a lion was referred to in the Bible by Prophet Jeremiah as Esther, the Queen of Heaven. A prayer as "she who dost make the green herd to sprint up" reminds us of Shakambari or Durga as the goddess of vegetation.
The mother goddess was also quite visible in Europe and Africa since times immemorial, and we see her in plenty in the Indus Valley. But she appears less in the Vedic period, from which we get no figurines or material evidence. The Satapatha and Taittiriya Upanishads, however, refer to "Ambika" but it is only in the Sutras of Boudhayana and Sankhayana that the name 'Durga' appears, for the first time. The Epics have stray references to Devi, Sakti, etc, but the ten-armed warrior goddess was not their focus area. The Bhisma Parva mentions Arjuna worshipping Durga and there are references to Skanda-Kartikeya killing Mahishasura. A few Puranas mention Durga, but it was only when the Devi Mahatmya section of the Markandeya Purana glorified Durga's victory over Mahishasura that she was legitimately inducted into the Hindu pantheon. Soon, the old Vedic triad of “Brahma, Vishnu and Maheshwar” gave way to “Vishnu, Siva and Devi” and Brahma was retired to Pushkar. Even the great Vedic god, Indra is remembered as a suffix to Hindu names, like Dharmendra or Narendra, as his temples disappeared.
Sculptures depict her well before the Devi Mahatmya, but not in the present Dasha-bhuja or Ashta-Bhuja forms. A terracotta image from the 1st century found at Nagar in Rajasthan is perhaps the earliest icon and it has the Mahisha, the lion and the trishul, but Durga has only four hands. Another set of six Kushana period statues in the Mathura Museum has the trishul and the buffalo, but no lion. J N Banerjea has described in detail the mature images of Mahishasura-Mardini of the Gupta period but we wonder why the first major text on Durga came only after the Gupta period. Texts and sculptures in Bengal portraying different images of the goddess started appearing at a little later, but it took several centuries for the resplendent image of the present day to be crafted together. Vernacular Ramayans like Kamban’s Tamil one of the 12th century and Krittibasa’s Bengali version in the 15th century weaved together disparate popular perceptions about the warriorgoddess and Rama’s Akal-bodhana into clear yet definitively regional narratives.
About the buffalo, my submission is that it had to be slaughtered and driven away from its natural habitat in the low-lands by the emerging peasant groups, as they needed for more land for cultivation.
The timing of the Durga Puja in Ashwin-Kartik coincided with the ripening of the Aus crop that was most prevalent in this region for centuries before the Aman varieties took over. About the buffalo, my submission is that it had to be slaughtered and driven away from its natural habitat in the low-lands by the emerging peasant groups, as they needed for more land for cultivation. In America, the white colonists wiped off lakhs of ‘bisons’ from the Prairies to clear land for farming and also killed the bison-centric 'Red Indians’ as well. Durga as Mahishasura-Mardini may therefore have been a sacred legitimation, especially for Zamindars like Raja Krishna Chandra and Kansa Narayan who extended agriculture and their revenues.
R P Chanda and P C Bagchi have argued that the Simha-vahini Durga was imported into Bengal from outside after the Gupta period but others argue that she has local roots. In a sense, both are correct as there are strong Bengali elements and external components. In several images of Durga we see a strange ‘mount’ that looks more like the iguana (godhika or gosap) of Kalketu's Chandi rather than the more sanskritised lion. Even till the 19th century, patuas and chitrakars in Bengal had difficulty in depicting the lion as they had never seen one in their lives. In north India, however, she continues to ride the Royal Bengal tiger, how strange!
Durga appears with six or eight arms is part of the Shivaite religion in several places of Indonesia like Borobudur, Surabaya, Bandung and Prambanan. An inscription in Java mentions that King Airlangga worshipped Durga to win her support before a battle. During the height of Majapahit power in Java, Durga was worshipped as the fierce protector and her cult became even stronger in the 15th and 16th centuries. But as Islam took over, Durga was relegated to cremation grounds and cemeteries and therefore moved eastward to Hindu Bali, where she got more respect. Durga is also known in some other countries where the Hindu religion was exported.
