Historians have no literature or original Etruscan religious or philosophical texts on which to base knowledge of their civilization, so much of what is known is derived from grave goods and tomb findings. Princely tombs did not house individuals, but families who were interred over long periods. The decorations and objects included at these sites paint a picture of Etruscan social and political life. For instance, wealth from trade seems to have supported the rise of aristocratic families who in turn were likely foundational to the Etruscan oligarchic system of governance. Indeed, at some Etruscan tombs, physical evidence of trade has been found in the form of grave goods, including fine faience ware cups, which was likely the result of trade with Egypt. Additionally, the depiction of married couples on many sarcophagi provide insight into the respect and freedoms granted to women within Etruscan society as well as the emphasis placed on romantic love as a basis for marriage pairings.

Although many Etruscan cities were later assimilated by Italic, Celtic, or Roman ethnic groups, the Etruscan names and inscriptions that survive within the ruins provide historic evidence as to the range of settlements the Etruscans constructed. Etruscan cities flourished over most of Italy during the Roman Iron Age. According to ancient sources, some cities were founded by the Etruscans in prehistoric times and bore entirely Etruscan names. Others were later colonized by the Etruscans from Italic groups.
Nonetheless, relatively little is known about the architecture of the ancient Etruscans. What is known is that they adapted the native Italic styles with influence from the external appearance of Greek architecture. Etruscan architecture is not generally considered part of the body of Greco-Roman classical architecture. Though the houses of the wealthy were evidently very large and comfortable, the burial chambers of tombs and the grave-goods that filled them survived in greater numbers. In the southern Etruscan area, tombs contain large rock-cut chambers under a tumulus in large necropoli.
There is some debate among historians as to whether Rome was founded by Italic cultures and then invaded by the Etruscans, or whether Etruscan cultural objects were adopted subsequently by Roman peoples. In other words, it is unclear whether Etruscan cultural objects are influences upon Roman culture or part of native Roman heritage. Among archaeologists, the main criteria for deciding whether or not an object originated in Rome or descended to the Romans from the Etruscans is the date of the object, which is often determined by process of carbon dating. After this process, the opinion of ancient sources is consulted.
Although Diodorus of Sicily wrote in the first century of the great achievements of the Etruscans, little survives or is known of it. Most Etruscan script that does survive are fragments of religious and funeral texts. It is evident, however, from Etruscan visual art that Greek myths were well known.
