Wood carving is one of the oldest arts of humankind. Wooden spears from the Middle Paleolithic, such as the Clacton Spear, reveal how humans have engaged in utilitarian woodwork for millennia. Indeed, the beginnings of the craft go so far back that, at least where timber is present, the use of wood exists as a universal in human culture as both a means to create or enhance technology and as a medium for artistry. The North American Indian carves his wooden fish-hook or his pipe stem just as the Polynesian works patterns on his paddle. The native of Guyana decorates his cassava grater with a well-conceived scheme of incised scrolls, while the native of Loango Bay distorts his spoon with a design of figures standing up in full relief carrying a hammock. Wood carving is also present in architecture.
