The eighteen different schools which have obtained celebrity throughout the Buddhist world are mentioned in the Cingalese collection, and in that of all the northern Buddhists, including the Chinese. In the manuscript which the writer possesses nothing is mentioned respecting these schools but their respective names. Had the chief opinions held out by each school been given out, they would have been expounded here at great length and with a scrupulous correctness. Such not being the case, the author has thought that it was useless to the reader to lay before him a dry and uninteresting array of names. [33] It has been thought of some importance to mention in a particular note all the principal epochs named in the course of this work, and to show how they stand relatively to the Christian era. As a matter of course, the starting-point for the reckoning and computing of years is the epoch of Gaudama’s death, which is fixed by the southern Buddhists in the year 543 B.C. The exactness of this epoch has been contested by A. Cunningham, one of the greatest authorities in such matters. In his opinion, the epoch of Gaudama’s Neibban ought to be placed seventy years later. But as his views on this subject have not as yet been universally received by the learned in Europe, we will remain satisfied with the hitherto generally accepted data. The first era is that of King Eetzana, the grandfather of Gaudama by his mother’s side. It was made by the help and under the guidance of a famous hermit, named Deweela, who is mentioned as highly versed in the science of astronomy, such as it existed in those days. The king’s object was to correct the glaring errors that had crept into the calendar. It is said that he did away with the era 8640 on a Saturday, on the day of the new moon of Tabaong (March), and fixed the beginning of the new era on the following day, that is to say, on a Sunday, the first day after the new moon of the same month. This happened in the year 691 B.C. This new reckoning of years lasted only a hundred and forty-eight years, the epoch of Gaudama’s Neibban, 543 B.C. The second era, the most celebrated of all, is the religious one. King Adzatathat and the venerable Kathaba, actuated by the desire of rendering ever memorable the death of the founder of their religion, and paying to him a homage that would be re-echoed by succeeding generations, came to the resolution of doing away with the Eetzana computation, and fixed a new reckoning of years, from the annual revolution which witnessed that event, which, in the opinion of Buddhists, is the greatest of all. In the year 148, the first day of the month of Tagoo (April), which fell on a Sunday, was fixed as the beginning of the new computation, emphatically called the era of religion, 543 B.C. It is adopted by all the southern Buddhists.
