Stretching from the beaches of the Adriatic Sea to the banks of the Indus River, Alexander the Great’s empire was the largest the world had ever seen when he died in 323 BCE. His empire broke into several smaller kingdoms soon after, but his enduring legacy can be found in signs of Hellenistic cultural diffusion in ancient artifacts that survive today. The Metropolitan Museum of Art’s latest exhibition, Pergamon and the Hellenistic Kingdoms of the Ancient World, is a testament to this cultural interaction and the footprint Alexander left in history far beyond what his imagination could have conceived.
