This large and heavy copper alloy axe is from the ancient culture(s) of Northern Iran. The convex cutting edges are perpendicular to each other. It has a vertical shaft hole with a collar/ridge around the bottom. There are some obvious chips to the vertical cutting blade but it is otherwise very solid, stable and complete. Axes such as this one were in use from the late third millennium BCE throughout the second millennium BCE. The larger size indicates a date later in that timeframe. This particular specimen weighs an impressive 1964 grams. It is just over 27 cm in length and roughly 6 cm in height. Deshayes J. Les outils de bronze, de L'indus au Danube (IVe au IIe Millenaire).
