Nile boat
==Discovery==
The earliest evidence for an ancient boat on the Nile is a rock art pictograph that dates to the Mesolithic. The El Salha Archaeological Project of the Italian Institute for African and Oriental Studies has been working in the central Sudan since the fall of 2000. The project's priority is the archeology of the Mesolithic and Neolithic cultures of this region of the Nile Valley. Of great interest to maritime archeology is an elongated burial mound on the west bank of the Nile, 25 km south of Omdurman. Beneath this Post-Meriotic burial and disturbed deposits was a compact, homogeneous layer of the Khartoum Mesolithic. Diagnostic gastropods were in this layer and radiocarbon dating delineates a time span of 7050 to 6820 BC.
An important artifact that speaks to the early history of boat design and ship building was found in the Khartoum Mesolithic layer. A recognizable outline of Nile boat had been cut into a granite pebble.〔(The oldest representation of a Nile boat ) by D. Usai & S. Salvatori, Antiquity Vol 81 issue 314 December 2007, retrieved July 11, 2008.〕 This is the oldest known representation of a Nile boat, and the oldest depiction of a boat that is more advanced in design than a canoe. The dating of this pictograph pushes back the earliest evidence for Nile boats by 3,000 years.
