In addition to this general era, Buddhist nation has had, for one reason or for another, particular periods, from which they have reckoned time and computed years. It is probable that the reform in the calendar, necessitated by the errors introduced into it owing to incorrect computations, have given rise to several eras, which are generally known by the name of the kings under whose reign they have taken place, and by whose authority they have been introduced and brought into common use. The Burmans have the era called Dandoratha. It was introduced by Thamugdara, or, as spelt by others, Thamugdaritz, king of Prome, in the year of religion 625 = to 81 A.D. That monarch is represented as well informed and skilled in the knowledge of the astronomical calculations. The months were no longer in unison with the seasons. What did the royal reformer of the calendar do to remedy the evil? No other particular is mentioned in the manuscript which the writer has in his possession, except that the king did away with 622, and began the reformed computation with two, so that its beginning must be made to agree with the year 79 A.D. That era lasted only 562 years. The reformer on this occasion was Pouppa-dzau, king of Pagan, who is represented to us as well versed in the science of astronomical computations. This monarch imitated in this reform the conduct of the king of Prome. He did away with 560 years, and had his new era to begin with two. This happened in the year of religion 1182 = to 639 A.D. This is the common era used by the Burmese up to this day, and is known as the Pagan or Pouppa-dzau era. We find also mentioned occasionally the Thaton era. It is made to begin with the year of the arrival of the two Buddhist missionaries, Thauna and Outtara, in the great place of Thaton, in the year of religion 237 = to 306 B.C. Thirimathoka was, at that time, king of that country. That period of years has lasted 1362 years. It ended in the year of religion 1599 = 1156 A.D., when the king of Pagan, Naurata-dzau, invaded the country, possessed himself of Thaton, and carried away captive the last king, Mein-hnit. It is perhaps as well to mention here an epoch which has been, at all times, famous in the history of Buddhism in Burmah. I allude to the voyage which a religious of Thaton, named Buddhagosa, made to Ceylon in the year of religion 943 = to 400 A.D. The object of this voyage was to procure a copy of the scriptures. He succeeded in his undertaking. He made use of the Burmese or rather Talaing characters, in transcribing the manuscripts, which were written with the characters of Magatha. The Burmans lay much stress upon that voyage, and always carefully note down the year in which it took place. In fact, it is to Buddhagosa that the people living on the shores of the Gulf of Martaban owe the possession of the Buddhist scriptures. From Thaton, the collection made by Buddhagosa was transferred to Pagan, 656 years after it had been imported from Ceylon.
