This Elements series’ geographical scope dispels the traditional framework that typically separates studies of ancient Anatolia, the Caucasus, Arabia, Syria, Mesopotamia, Iran and Afghanistan. With maritime and overland routes linking the Mediterranean Sea and the Indian Ocean, West Asia played a highly significant role in ancient geopolitics and economics. Interdisciplinary in approach, volumes in this series synthesize the history, politics, economies, archaeology, architecture, art and religions of the region during the Hellenistic, Roman, Arsacid Parthian and Sasanian periods (ca. 350 BCE–650 CE). This was an era of exceptional contact between cultures, as well as political and religious change, that has received limited attention in publications intended for a wide audience. The series is organized into four broad categories: “Cities and Subregions,” “Politics, Economies and Networks,” “Cultural and Religious Life,” and “History of the Field” Overall, volumes cut across disciplinary boundaries and help the next generation of scholars and students continue to dissolve divisions between Parthian/Sasanian and Graeco-Roman studies.
