‘Etruscan religion’ aims to shed light on the apparent ‘mysterious origins’ of Etruscan religious practices. Evidence of sanctuaries and temples shows lavish architecture expenditure from the late sixth century onwards. Inscriptions indicate the formulaic and rule-bound nature of worship. We have two significant sources of evidence on Etruscan religion: burials and mirrors. Another interesting question is how the Etruscans imagined their deities. It is doubtful that they saw them in human form. They were much more interested in phenomena. Although the influence of the Greeks appears again here, they changed some aspects of this. Without losing the specificities of their own religion, the Etruscans perhaps found aspects of the Greek mythological world appropriate to their own.
