Rome, though in what consulship, or under what emperor, it is
impossible to determine. He married a woman of a noble family, by whom
he had two sons. The mother died in the flower of her age, and the sons,
at the distance of some time from each other, when their father was
advanced in years. The precise time of Quintilian's own death is
equally inauthenticated with that of his birth; nor can we rely upon an
author of suspicious veracity, who says that he passed the latter part of
his life in a state of indigence which was alleviated by the liberality
of his pupil, Pliny the Younger. Quintilian opened a school of rhetoric
at Rome, where he not only discharged that labourious employment with
great applause, (499) during more than twenty years, but pleaded at the
bar, and was the first who obtained a salary from the state, for
executing the office of a public teacher. He was also appointed by
Domitian preceptor to the two young princes who were intended to succeed
him on the throne.

After his retirement from the situation of a teacher, Quintilian devoted
his attention to the study of literature, and composed a treatise on the
Causes of the Corruption of Eloquence. At the earnest solicitation of
his friends, he was afterwards induced to undertake his Institutiones
Oratoriae, the most elaborate system of oratory extant in any language.
This work is divided into twelve books, in which the author treats with
great precision of the qualities of a perfect orator; explaining not only
the fundamental principles of eloquence, as connected with the
constitution of the human mind, but pointing out, both by argument and
observation, the most successful method of exercising that admirable art,
for the accomplishment of its purpose. So minutely, and upon so
extensive a plan, has he prosecuted the subject, that he delineates the
education suitable to a perfect orator, from the stage of infancy in the
cradle, to the consummation of rhetorical fame, in the pursuits of the
bar, or those, in general, of any public assembly. It is sufficient to
say, that in the execution of this elaborate work, Quintilian has called
to the assistance of his own acute and comprehensive understanding, the
profound penetration of Aristotle, the exquisite graces of Cicero; all
the stores of observation, experience, and practice; and in a word, the
whole accumulated exertions of ancient genius on the subject of oratory.

It may justly be regarded as an
