A common misconception about the Parthians is that they lacked interest in the development of learning, science and technology. This belief is derived from the paucity of the available evidence, the lack of archaeological studies as well as subjective bias.
Technology certainly continued to evolve during Parthian rule. A dramatic discovery of a tomb by German Archaeologist Wilhelm Konig at Khujut Rabu (near modern Baghdad in Iraq) in 1936 found two near intact jars dated to the Parthian dynasty (approx. 250 BC-224 AD) which are possibly the world’s oldest batteries.
