Early scholars like H.C.P. Bell, who resided in Sri Lanka most of his life, claim that Buddhism came to the Maldives from Sri Lanka and that the ancient Maldivians had followed Theravada Buddhism. Since then, new archaeological discoveries point to Mahayana and Vajrayana Buddhist influences, which are likely to have come to the islands straight from the Subcontinent. An urn discovered in Maalhos (Ari Atoll) in the 1980s has a Vishvavajra inscribed with Protobengali script. This text was in the same script used in the ancient Buddhist centres of learning in Nalanda and Vikramashila. There is also a small Porites stupa in the Museum where the directional Dhyani Buddhas (Jinas) are etched in its four cardinal points as in the Mahayana tradition. Some coral blocks with fearsome heads of guardians are also displaying Vajrayana Iconography. All these relatively recent archaeological discoveries are today exhibited in a side room of the small National Museum in Male' along with other artifacts.
