Mampalli_copper_plate
The Mampalli copper plate (974 AD), also romanised as Mamballi, records a donation from the chiefly family of Venad, present-day Kerala, to the Chengannur Temple.[1] The inscription is the earliest epigraphical record to mention the Kollam Era (Kollan-Tonri Era, 149).[1][2]
The record is engraved on both sides of a single copper plate in Vattezhuthu with Grantha characters in an early form of Malayalam language. The plate was originally owned by Mampalli Madhom, near Trivandrum (now at Padmanabhapuram Museum).[1]
A second plate, companion to the first one and ascribed approximately to the same date, is owned by Mampalli Madhom.[1]
