Artifact from an Ancient Civilization!
Found this in my garden in the spring and it is called a single tree hook. It is where a horse's harness attaches to a single tree which allows a horse to pull a wagon, plow, or other implement. It also hardly qualifies as coming from an ancient civilization as horses were commonly used, in day to day life, in the early parts of the 20th century! Just serves as a reminder that while today we expect our online orders to be delivered, from the other side of the country, in two days that it was not that long ago that visiting your nearest large city would have taken that long!
Always important to value what we have today and to also keep your focus on what really matters!
