Sthanu Ravi Varma (Early Malayalam and Tamil: Ko Tanu Iravi), known as the Kulasekhara, was the Chera Perumal ruler of Kerala in southern India from 844/45 to c. 870/71 AD.

[17]The direct (sovereign) authority of the Chera Perumal king was perhaps restricted to the country around capital Makotai (Mahodaya, present-day Kodungallur) in central Kerala.

[18] His pan-Kerala kingship was perhaps only ritualistic, remaining nominal compared to the power that local chieftains (the Udaiyavar) wielded politically and militarily in distant regions.

[20] It is known that the two rulers jointly conferred military honours on a chief of Tanjore called Vikki Annan (who was the husband of "Kadamba Mahadevi"), probably a Ganga prince.

The inscription records that Ayyan Adikal granted land and serfs to a Christian church at Quilon, built by Mar Sapir Iso, and entrusted its maintenance to trade guilds anjuvannam and manigramam.

The wife of Vikki Annan, who was honoured by the king Kandan Rajakesari Varma who was the possessor of several elephants ["tondai-nadu-pavina-cholan-pal-yanai-ko-kandan"] and by the Cheraman Ko Tanu Iravi, with [the privilege of using] the seat [of honour], the chauris, the palanquin, the drum, a palace, [royal] dinner, [participation in it perhaps] and the bugle and [who was presented] with a battalion of elephants and the hereditary title of Sembiyan Tamilavel - Kadamba Mahadevi gave to the god Mahadeva at Tiruneyyttanam a perpetual lamp, for which the number of sheep given by her is a hundred.

[41] [42] The opening verse of the commentary also gives an indirect invocation to the lord called "Sthanu" (carefully composed to be applicable to god Siva and the ruling king).
