Solution:

• The Tharisapalli copper plates document Venad ruler Ayyanadikal Thiruvadikal’s donation of a region and its administration to Tharisapalli church in Kollam established by Marsapir Imbo.
• Venad Adikal was a ruler under the Kulasekhara king Sthanu Ravi Perumal and the donation was in the fifth year (AD 849) of the latter’s reign.
• Though the plates belong to Kollam, these title deeds are kept at the Syrian Christian Church, Kottayam and Marthoma Church, Thiruvalla and are called “Kottayam cheppedukal”. These are the first important inscriptions in the state of which the exact date was found.
