Rajashekhara Varman

Laghubhaskariyavyakhya The Laghubhaskariyavyakhya, a mathematical commentary composed in the court of king Sthanu Ravi Kulasekhara in c. 869/70 AD, mentions a Chera ruler named "Ramadeva", who "marched out to fight the enemies on receiving information from the spies". Some scholars identify this "Ramadeva" with Rama Rajasekhara. Ramadeva is described as the king ("Raja") and a member of the Solar Dynasty ("ravi-kula-pati") in Chapter IIII of the Laghubhaskariyavyakhya. In the Keralolpatti legends on the origin of Kerala, the first Chera ruler (the Cheraman Perumal) is described as a contemporary of Vasubhatta, who is elsewhere in the same work portrayed as a courtier of king Kulasekhara and a disciple of a certain Mahabharata Bhatta.

Two later commentaries on Yudhisthiravijaya — "Vijayadarsika" by Acyuta and "Ratnapradipika" by Sivadasa — argue that "Rama" was the personal name of the king whose regnal title was "Kulasekhara". However, this view is generally regarded as unacceptable for several reasons.

Rajasekhara is also tentatively identified with king referred to as "Co-qua-rangon" in the extant text of the Thomas of Cana copper plates.
