The inscription is repeated on each of the four pillars which once supported the roof of an open pavilion on the southern terrace of the Ruvanväli or Rankot-dāgaba in Poḷonnaruva. According to the inscription, this pavilion was built to provide a place from which king Niśśanka Malla could pay his adorations to the relics enshrined in the dāgaba. Presumably, the pavilion originally contained an āsana (throne) or dias for this purpose. The pillars are square at the top and bottom with an octagonal section in the centre. All four pillars are fallen and two are broken. The inscription gives an account of some of Niśśaṅka-Malla’s acts, before describing the king’s use of the pavilion. Niśśaṅka-Malla reigned from 1187 to 1196 A.D. No specific date is given in the inscription but, as Wickremasinghe notes, the text must have been composed after the fourth year of Niśśaṅka-Malla’s reign because it refers to the king’s visit to Anurādhapura, which took place in his fourth regnal year, and to his later tours of inspection.
Of the four copies of the inscription on the four pillars, two were first transcribed and translated by Rhys Davids in 1875 for the Journal of the Royal Asiatic Society. The third copy was edited by Müller in Ancient Inscriptions in Ceylon (1883). The information below relates to the fourth copy, which was transcribed and translated for the first time by Wickremasinghe in Epigraphia Zeylanica 2 (1912-27). The fourth copy differs from the other three in the number of lines on each side and also in the beginning and end of each line.
