Reading the Laguna copperplate inscription
(Thin copper plate measuring less than 8 × 12 inches (20 × 30 cm) in size and inscribed with small writing that had been hammered into its surface.)
The Laguna Copperplate inscription (LCI) is the earliest known written document found in the Philippines. The plate was found in 1989 by Alfredo Evangelista in Lumban river near Laguna de Bay. Evangelista was dredging sand in the mouth of the river when he uncovered this sheet of copper with strange writing on it. He sold it to the Philippine National Museum for some 2000 pesos.
