The Romans were fascinated by the Etruscans. They adopted much of their culture and even compiled a significant written history of them. Sadly those manuscripts have not survived. Hopefully an intact, well preserved library will one day be found at Pompeii or somewhere.
That would be nice. Emperor Claudius studied Etruscan and wrote a history of the Etruscans (all his work is lost, apart from some quotes I think), and the inscriptions of the Etruscans are largely short and/or abbrev. and carved on grave monuments. A couple weeks ago I was working on an Etruscan topic which I haven't used yet, will soon, which was primarily about one of the longer known texts, a grave monument that is large and inscribed on all sides.
The Romans got a lot of civil engineering techniques from the Etruscans, probably because they conquered Etruria (Roman kings had been Etruscans long before). This pyramidal altar stands in a valley that has Etruscan burials and other traces -- and the valley itself is artificial, literally carved down out of the rock.
