The Archaeologist has similar functions as in Civilization V: Brave New World, although he can't create Landmark improvements. A single Archaeologist, however, can extract Artifacts from three sites before vanishing, which justifies its high cost and specific requirements. Note that one Archaeological Museum may support only one Archaeologist! After its parent city has produced him, and he has been expended, you will need another Museum in another city to continue exploring Antiquity Sites! The idea is that an Archaeologist is sort of an extension of the Museum, sent by it, as it were, to complete its collection. While there are free slots in the Museum (i.e. the collection is incomplete), it may send out and maintain an Archaeologist; when the collection is complete, the Museum doesn't need Archaeologists anymore.
Archaeologists cannot enter another civilization's territory without an Open Borders treaty, unless your civilization has built the Terracotta Army.
Civilopedia entry Edit
Archaeologists study human behavior in the past, primarily through the excavation and analysis of human fossils, the ruins of buildings, and the remains of human artifacts. Although controversies rage about the ownership of artifacts, treasures, and human remains recovered, thousands of archaeologists still operate around the world at excavations sites, in museums, and on university campuses. These men and women work to undercover the common beliefs and daily activities of various peoples throughout history, furthering our understanding of our own history.
