The seed plough allowed ancient farmers to minimise their hours of toil, enabling them to turn the soil, deposit seeds into the furrow, and turn back the soil in one pass. A Mesopotamian invention, it is said that the god Enlil provided the inspiration for the device by outlining his designs in the stars. While this invention saved both time and resources, it also made ploughing a skill in its own right, which contributed to the growth of specialisation in agriculture. Regions began to organise their skilled workers and natural resources to focus on a single crop.
