piracy as a means of acquiring valuable resources, such as land, prestige, goods, and slaves. It is likely that individuals taken in battle would be ransomed back to their families and clans at high cost. Prisoners could also potentially be sacrificed on tombs as an honor to fallen leaders of Etruscan society, not unlike the sacrifices made by Achilles for Patrocles. Cities The range of Etruscan civilization is marked by its cities. They were entirely assimilated by Italic, Celtic, or Roman ethnic groups, but the names survive from inscriptions and their ruins are of aesthetic and historic interest in most of the cities of central Italy. Etruscan cities flourished over most of Italy during the Roman Iron Age, marking the farthest extent of Etruscan civilization. They were gradually assimilated first by Italics in the south, then by Celts in the north and finally in Etruria itself by the growing Roman Republic. That many Roman cities were formerly Etruscan was well known to all the Roman authors. Some cities were founded by Etruscans in prehistoric times, and bore entirely Etruscan names. Others were colonized by Etruscans who Etruscanized the name, usually Italic. Culture Religion The Etruscan system of belief was an immanent polytheism; that is, all visible phenomena were considered to be a manifestation of divine power and that power was subdivided into deities that acted continually on the world of man and could be dissuaded or persuaded in favour of human affairs. How to understand the will of deities, and how to behave, had been revealed to the Etruscans by two initiators, Tages, a childlike figure born from tilled land and immediately gifted with prescience, and Vegoia, a female figure. Their teachings were kept in a series of sacred books. Three layers of deities are evident in the extensive Etruscan art motifs. One appears to be divinities of an indigenous nature: Catha and Usil, the sun; Tivr, the moon; Selvans, a civil god; Turan, the goddess of love; Laran, the god of war; Leinth, the goddess of death; Maris; Thalna; Turms; and the ever-popular Fufluns, whose name is related in some way to the city of Populonia and the populus Romanus, possibly, the god of the people. Ruling over this pantheon of lesser deities were higher ones that seem to reflect the Indo-European system: Tin or Tinia, the sky, Uni his wife (Juno), and Cel, the earth goddess. In addition,
