Poeticon Astronomicon, with a treatise on agriculture, commentaries on Virgil, the lives of eminent men, and some other productions now lost. His remaining works are much mutilated, and, if genuine, afford an unfavourable specimen of his elegance and correctness as a writer.
CELSUS was a physician in the time of Tiberius, and has written eight books, De Medicina, in which he has collected and digested into order all that is valuable on the subject, in the Greek and Roman authors.
The professors of Medicine were at that time divided into three sects, viz., the Dogmatists, Empirics, and Methodists; the first of whom deviated less than the others from the plan of Hippocrates; but they were in general irreconcilable to each other, in respect both of their opinions and practice.
Celsus, with great judgment, has occasionally adopted particular doctrines from each of them; and whatever he admits into his system, he not only establishes by the most rational observations, but confirms by its practical utility.
In justness of remark, in force of argument, in precision and perspicuity, as well as in elegance of expression, he deservedly occupies the most distinguished rank amongst the medical writers of antiquity.
It appears that Celsus likewise wrote on agriculture, rhetoric, and military affairs; but of those several treatises no fragments now remain.
