the Duties of a Citizen. He calls it a great and a laborious work, yet
worthy of his pains, if he could succeed in it. This likewise was
written in the form of a dialogue, in which the speakers were Scipio,
Laelius, Philus, Manilius, and other great persons in the former times of
the Republic. It was comprised in six books, and survived him for
several ages, though it is now unfortunately lost. From the fragments
which remain, it appears to have been a masterly production, in which all
