Much of Roman Religion was derived from the Etruscans, but the Roman preferred to seek Greek roots.  Roman origin myths, on the other hand, said that they sprung from Aeneas, A Trojan.  Roman death and afterlife beliefs also had Etruscan roots, but they assiduously altered them to mimic Greek belief structures.
