<P> The Twelve Tables are sufficiently comprehensive that their substance has been described as a' code', although modern scholars consider this characterisation exaggerated . The Tables were a sequence of definitions of various private rights and procedures . They generally took for granted such things as the institutions of the family and various rituals for formal transactions .

Some scholars dispute the veracity of any claim that the Romans imitated the Greeks in this respect or suggest that they visited the Greek cities of Southern Italy, and did not travel all the way to Greece .
