How does Etruscan Art influence the Latin populace with its architecture, sculp/paintings and decorative arts?
This is a rather large subject, and the fact is that Roman art was a synthesis of Greek, Etruscan and more original Roman elements. By the time of the Empire, it had really thrown off Etruscan influence. Architecture — especially temples — was probably the most heavily affected by Etruscan temple types. You can read the site below and others on Roman and Etruscan art, but you really should be looking at books on both Etruscan and Roman material. Some bibliography is included on the second site I’ve given you.
