By the 4th century AD, and most likely before that, ancient people from the Philippines have been making giant warships, where the earliest known archaeological evidences have been excavated from Butuan, where the ship was identified as a balangay and dated at 320 AD. The oldest, currently found, artifact with a written script on it is the Laguna Copperplate Inscription, dated 900 AD. The plate discusses the payment of a debt. The Butuan Ivory Seal is the earliest known ivory art in the country, dated between the 9th to 12th century AD. The seal contains carvings of an ancient script. During this period, various artifacts were made, such as the Agusan image, a gold statue of a deity, possibly influenced by Hinduism and Buddhism. From the 12th to 15th century, the Butuan Silver Paleograph was made. The script on the silver has yet to be deciphered. Between the 13th–14th century, the natives of Banton, Romblon crafted the Banton cloth, the oldest surviving ikat textile in Southeast Asia. The cloth was used as a death blanket. By the 16th century, up to the late 19th century, Spanish colonization influenced various forms of art in the country.
