now remain only a few fragments, scattered in
different parts of his other writings. He published, about the same
time, a collection of the principal speeches which he had made in his
consulship, under the title of his Consular Orations. They consisted
originally of twelve; but four are entirely lost, and some of the rest
are imperfect. He now published also, in Latin verse, a translation of
the Prognostics of Aratus, of which work no more than two or three small
fragments now remain. A few years after, he put the last hand to his
Dialogues upon the Character and Idea of the perfect Orator. This
admirable work remains entire; a monument both of the astonishing
industry and transcendent abilities of its author. At his Cuman villa,
he next began a Treatise on Politics, or on the best State of a City, and
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

several ages, though it is now unfortunately lost. From the fragments
which remain, it appears to have been a masterly production, in which all

occupied the thoughts of this celebrated personage, he yet found leisure
to write several philosophical tracts, which still subsist, to the
gratification of the literary world. He composed a treatise on the
Nature of the Gods, in three books, containing a comprehensive view of
religion, faith, oaths, ceremonies, etc. In elucidating this important
subject, he not only delivers the opinions of all the philosophers who
had written anything concerning it, but weighs and compares attentively
all the arguments with each other; forming upon the whole such a rational
and perfect system of natural religion, as never before was presented to
the consideration of mankind, and approaching nearly to revelation. He
now likewise composed in two books, a discourse on Divination, in which
he discusses at large all the arguments that may be advanced for and
against the actual existence of such a species of knowledge. Like the
preceding works, it is written in the form of dialogue, and i
