the work has been lost, but having been substantially quoted by augustine in his "de civitate dei" (published ad 426) its contents can be reconstructed in parts. to a lesser extent, quotes from the work have also been transmitted by other authors, including (among others) pliny (1st c.), gellius (2nd c.), censorinus (3rd c.), servius (4th/5th c.), nonius (4th/5th c.), macrobius (5th c.), priscian (5th/6th c.).
