The word "paper" derives from papyrus, the name of the ancient material manufactured from beaten reeds in Egypt as far back as the third millennium B.C.[4] Indeed, the earliest known example of "paper folding" is an ancient Egyptian map, drawn on papyrus and folded into rectangular forms like a modern road map.[2] However, it does not appear that intricate paper folding as an art form became possible until the introduction of wood-pulp based papers.[5]
