"This extraordinary European also induced his grateful sovereign King Nárái to repair the old city of Lopha-buri (Louvô), and construct there an extensive royal palace on the principles of European architecture. On the north of this palace Constantine erected an extensive and beautiful collection of buildings for his own residence. Here also he built a Romish church. The ruins of these edifices and their walls are still to be seen, and are said to be a great curiosity. It is moreover stated that he planned the construction of canals, with reservoirs at intervals for bringing water from the mountains on the northeast to the city Lopha-buri, and conveying it through earthen and copper pipes and siphons, so as to supply the city in the dry season on the same principle as that adopted in Europe. He commenced also a canal, with embankments, to the holy place called Phra-Bat, about twenty-five miles southwest from the city. He made an artificial pond on the summit of Phra-Bat Mountain, and thence, by means of copper tubes and stop-cocks, conveyed abundance of water to the kitchen and bath-rooms of the royal residence at the foot of the mountain. His works were not completed when misfortune overtook him. "After the demise of Nárái, his unacknowledged son, born of a princess of Yunnan or Chiang-Mai, and intrusted for training to the care of Phya Petcha raja, slew Nárái's son and heir, and constituted his foster-father king, himself acting as prime-minister till the death of his foster-father, fifteen years after; he then assumed the royal state himself. He is ordinarily spoken of as Nai Dua. Two of his sons and two of his grandsons subsequently reigned at Ayuthia. The youngest of these grandsons reigned only a short time, and then surrendered the royal authority to his brother and entered the priesthood. While this brother reigned, in the year 1759, the Birman king, Meng-luang Alaung Barah-gyi, came with an immense army, marching in three divisions on as many distinct routes, and combined at last in the siege of Aynthia.
