The traditional pottery of the Philippines was notable for its generous but simple and varied forms. Regular patterns were produced by impression. For example string or woven objects, or might be geometric (X-shaped or V-shaped). Figural decoration was quite exceptional. The pottery might be painted red, brown or black, or sometimes glazed. The import of Chinese porcelain tempered the originality of the native ware. The Manunggul Jar excavated in Palawan is an evidence of the high artistic level which the art attained during the ancient times. The large burial jar has a cover which features tow men rowing a boat, it was thought that the crown ornament of the cover showed the soul of the dead being ferried into the next world.
