Note: One of the things the Etruscans passed down to the Romans was the art of divination. "The inspection of the entrails of a sacrificial victim, especially of the liver ... was thought to give a clue to the future," according to Arcana Mundi: Magic and the Occult in the Greek and Roman Worlds (p.309). The technique was called Etrusca disciplina 'Etruscan art,' or haruspicina ... and its practitioners were called haruspices." According to the Encyclopedia Britannica, this kind of divination was Mesopotamian in origin, suggesting that the Etruscans had some kind of contact with the Near East.
"The haruspices observed and interpreted three kinds of phenomena: the entrails of animals; unnatural things or events in nature; and lightning," according to Cicero (Arcana Mundi, p. 310). "In Rome, a body of sixty haruspices, headed by a chief haruspex, became a threat to the augures, a rival group, but the two techniques were practiced side by side for centuries." (Ibid) The augurs interpreted"the will of the gods by studying the flight of birds: whether they are flying in groups or alone, what noises they make as they fly, direction of flight and what kind of birds they are. This was known as 'taking the auspices.'" (Wikipedia)
