Great Temple of the Aten, timber was used for structural support and the public buildings within the Temple had stone columns and were built of other stones for more support. Stone columns conformed to the usual style found elsewhere in Egypt, representing either palm-frond or papyrus. To lay out structural elements like offering tables and pits on a plaster floor, string was used. The string was first dipped in black paint and stretched tightly and was allowed to touch the ground, leaving a mark. In some instances the string was even pushed into the plaster floor, leaving a shallow groove. A similar technique was used to divide up wall surfaces before they were decorated with relief. The actual construction of the temple was accomplished in a series of steps. Before anything was built, there was already some kind of dedication ceremony at the site. A ceremonial gateway with receptacles for liquid offerings stood at the beginning of a paved avenue. The avenue extended eastward and was lined with sphinxes, but they were later replaced by trees (tree pits, some still containing tree roots, have been excavated). The avenue led up to a small mud-brick shrine which was later built into the main design scheme of the Temple. The first main construction undertaken by Akhenaten was the building of the temenos wall, enclosing a huge area of 229m x 730m. As the wall was being completed, the stone Sanctuary at the east end of the enclosure was built. This Sanctuary seemed to function on its own for some time until a few years later when Akhenaten added the Gem-Aten on the west side of the enclosure. With this addition, the original ceremonial gate had to be taken down and a raised causeway was built over it. The Gem-Aten was originally constructed in stone, but it seems that as time went on Akhenaten ran low on materials and the latter part of the Gem-Aten was finished with mud-brick. It is unknown exactly how the Temple walls were decorated because the entire area was destroyed later on, but fragments that have been found show that there were many statues of Akhenaten and his family placed all around the Temple. Layout The Great Temple of the Aten lay to the north of the Central City part of Akhetaten and was separated from the Palace by many storehouses. The Temple was oriented on an east-west
