The Butuan Palaeograph, also known as the Butuan Silver Strip is a piece of metal with inscriptions found in Butuan province in mid-1970s by a team of archaeologists from the National Museum. Treasure hunters who were looking for old ceramics and gold ornaments discovered this metal strip inside a wooden coffin. Coffins of the same characteristics, which dated back to the 14th and 15th centuries, were found in the site, however, according to Dr. Jesus Peralta, found inside were human fossils with artificially deformed skulls - a practice limited to Southern Philippines and unpopular in Luzon. Because of the similarities found between the coffins, it is reasonable for the archaeologists to assume that the latter came from that same era. But debates arose regarding the origin of the said artifact, but until now, it is considered to belong to Butuan where it was found. Dr. Boechari of Indonesia, said Peralta, identified the writings as very close to a Javanese script that existed from 12th to 15th century. This yet-to-be-decipher Butuan palaeograph is now in the hands of Proceso Gonzales, the city engineer of Butuan.
