Olynthos was a key city in 4th century Greece, famous for its fall to Philip of Macedon's seige and its subsequent abandonment. That even makes the site unique since it was never again settled, thus preserving the site in a way that has drawn comparisons to Pompeii. David Robinson was the first to excavate this important site, and this is the second of his site reports published in the American Journal of Archeology. It includes photographs, topographical charts, and the city plan, and includes more single artifacts than the first report, including what may be a urinal and the remains of the Byzantine church near the site. This article is of interest to historians of Greece, Macedonia, and the history of Archeology.
