Topographical Survey of Thebes, Tápé, Thaba, or Diospolis Magna.

In 1827 and 1828 Wilkinson carried out elaborate excavations at Thebes, where he uncovered and opened many tombs. His topographical efforts eventually crystallised into the first comprehensive plan of Western Thebes. Other maps had been made of the area, but none had the scope and detail of Wilkinson’s. Among the details he chose to include, was the sycamore tree by the landing, drawn prominently and clearly. For some reason of his own, he insert a plan of the pyramid of Giza in this plan. By the time he returned to England it was ready for publication.
Wilkinson prepared this map of the topographical survey, and it was published by the Royal Geographical Society in 1830. Letronne described it as the most complete and substantial work on Egypt since the "Description de l'Egypte" had been published. The " Topography of Thebes " was also intended as a guide for travellers; it was Wilkinson's first popular work.
