Rock engravings, also known as petroglyphs, are among the earliest forms of Philippine visual art. A famous example is the Angono-Binangonan Petroglyphs in Rizal, which date back to the late Neolithic period (around 3000 BCE). These engravings are found in caves and rock shelters and represent early human attempts at artistic expression.Other options like pottery and weaving are also ancient, but rock engraving is specifically associated with cave art.
