tinguished pupil, Dionysius Thrax (born c. 166 B.C.), drew up a Greek
grammar which continued in use for more than thirteen centuries. The
most industrious of the successors of Aristarchus was Didymus (c. 65
B.C.-A.D. 10), who, in his work on the Homeric poems, aimed at restoring
the lost recensions of Aristarchus. He also composed commentaries on the
lyric and comic poets and on Thucydides and Demosthenes; part of his
commentary on this last author was first published in 1904. He was a
teacher in Alexandria (and perhaps also in Rome); and his death, about
A.D. 10, marks the close of the Alexandrian age. He is the industrious
compiler who gathered up the remnants of the learning of his
predecessors and transmitted them to posterity. The poets of that age,
including Callimachus and Theocritus, were subsequently expounded by
Theon, who flourished under Tiberius, and has been well described as
"the Didymus of the Alexandrian poets."

The Alexandrian canon of the Greek classics, which probably had its
origin in the lists drawn up by Callimachus, Aristophanes of Byzantium
and Aristarchus, included the following authors:--

_Epic poets_ (5): Homer, Hesiod, Peisander, Panyasis, Antimachus.

_Iambic poets_ (3): Simonides of Amorgos, Archilochus, Hipponax.

_Tragic poets_ (5): Aeschylus, Sophocles, Euripides, Ion, Achaeus.

_Comic poets, Old_ (7): Epicharmus, Cratinus, Eupolis, Aristophanes,
Pherecrates, Crates, Plato. _Middle_ (2): Antiphanes, Alexis. _New_
(5): Menander, Philippides, Diphilus, Philemon, Apollodorus.

_Elegiac poets_ (4): Callinus, Mimnermus, Philetas, Callimachus.

_Lyric poets_ (9): Alcman, Alcaeus, Sappho, Stesichorus, Pindar,
Bacchylides, Ibycus, Anacreon, Simonides of Ceos.

_Orators_ (10): Demosthenes, Lysias, Hypereides, Isocrates, Aeschines,
Lycurgus, Isaeus, Antiphon, Andocides, Deinarchus.

_Historians_ (10): Thucydides, Herodotus, Xenophon, Philistius,
Theopompus, Ephorus, Anaximenes, Callisthenes, Hellanicus, Polybius.

The latest name in the above list is that of Polybius, who died about
123 B.C. Apollonius Rhodius, Aratus and Theocritus were subsequently
added to the "epic" poets. Philosophers, such as Plato and Aristotle,
were possibly classed in a separate "canon."

While the scholars of Alexandria were mainly interested in the _verbal
criticism_ of the Greek _poets_, a wider variety of studies was the
characteristic of the school of Pergamum, the literary riv
