he said was still Greek even at such a late time: The Indo-Greeks may also have had some influence on the religious plane as well, especially in relation to the developing Mahayana Buddhism. Mahayana Buddhism has been described as "the form of Buddhism which (regardless of how Hinduized its later forms became) seems to have originated in the Greco-Buddhist communities of India, through a conflation of the Greek Democritean–Sophistic–Pyrrhonist tradition with the rudimentary and unformalized empirical and skeptical elements already present in early Buddhism". Indo-Greek kings: their coins, territories and chronology Today 36 Indo-Greek kings are known. Several of them are also recorded in Western and Indian historical sources, but the majority are known through numismatic evidence only. The exact chronology and sequencing of their rule is still a matter of scholarly inquiry, with adjustments regular being made with new analysis and coin finds (overstrikes of one king over another's coins being the most critical element in establishing chronological sequences). There is an important evolution of coin shape (round to square) and material (from gold to silver to brass) across the territories and the periods, and from Greek type to Indian type over a period of nearly 3 centuries. Also, the quality of coinage illustration decreases down to the 1st century AD. Coinage evolution is an important point of Indo-Greek history, and actually one of the most important since most of these kings are only known by their coins, and their chronology is mainly established by the evolution of the coin types. The system used here is adapted from Osmund Bopearachchi, supplemented by the views of R C Senior and occasionally other authorities.
