3300 BC: The first depiction of a ship using cloth sails in found in Egyptian paintings.It shows a wagon with four wheels and two axles. 3500 BC: The Bronocice pot from Southern Poland illustrates a wheeled vehicle.A rock carving in Azerbaijan dating from ~10,000 BCE shows a reed boat manned by about 20 paddlers. The oldest recovered boat in the world is the 3 meter long Pesse canoe constructed around 8,000 BCE, however far earlier boats most likely existed. Egyptian rock paintings illustrate canoes, dugouts and rafts. The intention of this timeline is to emphasize innovation that has been created, rather than hypothesized, although often both events are cited in this Timeline. Sometimes several inventors create an important innovation around the same time, or an innovation may be invented in an impractical form many years before another inventor improves the invention into a practical form. Note: Dates for inventions are often controversial. If you are aware of a significant mechanical engineering innovation that is not listed, you are encouraged to add it to this timeline. The resulting inventory was then prepared into a Timeline, to which additional mechanical engineering innovations are added periodically as information and documentation becomes available. The extensive inventory then added some items from a listing prepared by the Institution of Mechanical Engineers (IMechE). This timeline initially started as an inventory of significant mechanical engineering innovation by the History and Heritage Committee of the American Society of Mechanical Engineers (ASME).
