(1) Today in the Suan Phrik Sub-district.
(2) Niello is the process and the result of annealing (literally blackening) or fixing by fusion on a decoratively incised, polished metal surface (usually silver, but occasionally gold), forming an opaque, black (non-mercurial) amalgam of silver, copper and lead. [7]
(3) The Jakkrawat Phachaiyon Maha Prasat was built in the reign of King Prasat Thong in 1632 CE, astride the palace’s east wall (near the southern end) at the edge of the parade ground, from which the king reviewed his troops and enjoyed martial displays. The palace, however, had three storeys. [8]
(4) There is some mystery surrounding the discovery of this image. Amatyakul places the discovery in the reign of Rama I (1782–1809 CE). An information board at Wat Phutthaisawan also gives 1784 CE as the year of the discovery, and both sources refer to Krom Luang Thepphonphak as the discoverer. The problem is that this prince was born in 1785 CE and became director of the Royal Elephant Department in the reign of Rama II, thus, after the death of Rama I.
