both poets and orators, may be considered as half-Greek: I speak of
Livius [844] and Ennius [845], who are acknowledged to have taught both
languages as well at Rome as in foreign parts [846]. But they (507) only
translated from the Greek, and if they composed anything of their own in
Latin, it was only from what they had before read. For although there
are those who say that this Ennius published two books, one on "Letters
and Syllables," and the other on "Metres," Lucius Cotta has
satisfactorily proved that they are not the works of the poet Ennius, but
of another writer of the same name, to whom also the treatise on the
"Rules of Augury" is attributed.

II. Crates of Mallos [847], then, was, in our opinion, the first who
introduced the study of grammar at Rome. He was cotemporary with
Aristarchus [848], and having been sent by king Attalus as envoy to the
senate in the interval between the second and third Punic wars [849],
soon after the death of Ennius [850], he had the misfortune to fall into
an open sewer in the Palatine quarter of the city, and broke his leg.
After which, during the whole period of his embassy and convalescence, he
gave frequent lectures, taking much pains to instruct his hearers, and he
has left us an example well worthy of imitation. It was so far followed,
that poems hitherto little known, the works either of deceased friends or
other approved writers, were brought to light, and being read and
commented on, were explained to others. Thus, Caius Octavius Lampadio
edited the Punic War of Naevius [851], which having been written in one
volume without any break in the manuscript, he divided into seven books.
After that, Quintus Vargonteius undertook the Annals of Ennius, which he
read on certain fixed days to crowded audiences. So Laelius Archelaus,
and Vectius Philocomus, read and commented on the Satires of their friend
Lucilius [852], which Lenaeus Pompeius, a freedman, tells us he studied
under Archelaus; and Valerius Cato, under Philocomus. Two others also
