The religiosity of the Etruscans most clearly manifested itself in the so-called 'discipline', that complex of rules regulating relations between men and gods. Its main basis was the scrupulous search for the divine will by all available means; ... the reading and interpretation of animal entrails, especially the liver ... and the interpretation of lightning.
