Ancient Egyptian art is the painting, sculpture, architecture and other arts produced by the civilization of ancient Egypt in the lower Nile Valley from about 3000 BC to 30 AD. Ancient Egyptian art reached a high level in painting and sculpture, and was both highly stylized and symbolic. It was famously conservative, and Egyptian styles changed remarkably little over more than three thousand years. Much of the surviving art comes from tombs and monuments and now there is an emphasis on life after death and the preservation of knowledge of the past. The wall art was never meant to be seen by people other than the afterlife for when they needed them.
