I am kind of surprised Egyptians weren't the first. As a fan of the Chinese's Three Kingdoms (both the history and the novel), I remember Zhuge Liang (諸葛亮) invented a wheelbarrow called Wooden Ox (木牛流马) during the war (according to the legend his design was really intelligent). The sad thing is his design was completely destroyed and unclear what the wheelbarrow actually look like.
