a varnish or resin was usually applied as a protective coating, and many paintings with some exposure to the elements have survived remarkably well, although those on fully exposed walls rarely have. Small objects including wooden statuettes were often painted using similar techniques. Many ancient Egyptian paintings have survived in tombs, and sometimes temples, due to Egypt's extremely dry climate. The paintings were often made with the intent of making a pleasant afterlife for the deceased. The themes included journeys through the afterworld or protective deities introducing the deceased to the gods of the underworld (such as Osiris). Some tomb paintings show activities that the deceased were involved in when they were alive and wished to carry on doing for eternity. From the New Kingdom period and afterwards, the Book of the Dead was buried with the entombed person. It was considered important for an introduction to the afterlife. Egyptian paintings are painted in such a way to show a side view and a front view of the animal or person at the same time. For example, the painting to the right shows the head from a profile view and the body from a frontal view. Their main colors were red, blue, green, gold, black and yellow. Paintings showing scenes of hunting and fishing can have lively close-up landscape backgrounds of reeds and water, but in general Egyptian painting did not develop a sense of depth, and neither landscapes nor a sense of visual perspective are found, the figures rather varying in size with their importance rather than their location. Architecture Ancient Egyptian architects used sun-dried and kiln-baked bricks, fine sandstone, limestone and granite. Architects carefully planned all their work. The stones had to fit precisely together, since no mud or mortar was used. When creating the pyramids, ramps were used to allow workmen to move up as the height of the construction grew. When the top of the structure was completed, the artists decorated from the top down, removing ramp sand as they went down. Exterior walls of structures like the pyramids contained only a few small openings. Hieroglyphic and pictorial carvings in brilliant colors were abundantly used to decorate Egyptian structures, including many motifs, like the scarab, sacred beetle, the solar disk, and the vulture. They described the changes the Pharaoh would go through to become a god. As early as 2600 BC the architect Imhotep made use
