In the Fall of 2017 the Penn Museum will open a new installation of its important collection of artifacts from the MIddle East. These artifacts were acquired by the Museum during decades of excavations carried out at sites in Iraq and Iran, including the sites of Ur, Nippur, Gawra and Khafajeh in Iraq and Hissar, Tureng Tepe, Chesm Ali/Rayy, Hasanlu and Surkh Dum in Iran. The galleries are conceived as a JOURNEY TO THE CITY. Through this lens we tell and illustrate the evolving story of human society from early villages to the great Urban centers of the ancient and Medieval world. In this website we explore one of the most important cross cutting themes is trade and exchange. This activity is almost as fundamental to humans as language and it serves to differentiate us from all other primates. This website is the product of a curatorial seminar in which students from a variety of interests joined together to explore trade and exchange across time and space.
