Of the two monolithic caves, one at the foot and the other half-way up, of ‘the rock’ at Trichinopoly, the latter alone contains inscriptions, two of which, published in South Indian Inscriptions, Vol. I, pages 29 and 30, state that the cave (upper) was constructed by Guṇabhara (i.e.) Mahēndravarman I. A verse inscription (No. 9 below) engraved on the beam over the inner row of pillars here, calls the cave ‘Laḷitāṅkura-Pallavēśvara-gṛiham’ after the title ‘Laḷitāṅkura’ of this king, which also occurs in his record at Pallāvaram. His birudas are engraved in bold Pallava-Grantha and Tamil characters on all the pillars in the upper cave at Trichinopoly. The outer wall of the sanctuary in this cave seems to have contained an inscription, but only a few letters of its first line are now visible, the rest being completely damaged. The name ‘Mahēndravikrama’ is found mentioned in the inscription on the extreme left outer pillar and most of the birudas occurring here are also found in the records of this king at Pallāvaram and other rock-cut excavations of his time. Some of these titles are unintelligible and appear to be Telugu in origin. The bottom of each of the four pillars contains a biruda in the Pallava-Tamil characters, of which only two are now clear, viz. Piṇapiṇakku and Chitti[rakāra]ppuli.

It is of interest to note that the birudas are alphabetically arranged and so engraved on the front face of the pillars. The same arrangement, though followed in the Pallāvaram inscription, is not so conspicuous there as in the present record (plates I and II).

The characters employed in the present inscriptions are of an ornate nature and provide an interesting contrast with the simpler variety of letters found in the Pallāvaram record of the same king, where almost all these birudas are repeated.

A description of the cave is found in the Memoir of the Archaeological Survey of India, No. 17, pages 13-15.
