k and that of Livy are the
only connected and detailed extant accounts of early Roman history.

Dionysius was also the author of several rhetorical treatises, in which
he shows that he has thoroughly studied the best Attic models:--_The Art
of Rhetoric_ (which is rather a collection of essays on the theory of
rhetoric), incomplete, and certainly not all his work; _The Arrangement
of Words_ ([Greek: Peri syntheseos onomaton]), treating of the
combination of words according to the different styles of oratory; _On
Imitation_ ([Greek: Peri mimeseos]), on the best models in the different
kinds of literature and the way in which they are to be imitated--a
fragmentary work; _Commentaries on the Attic Orators_ ([Greek: Peri ton
archaion rhetoron hypomnematismoi]), which, however, only deal with
Lysias, Isaeus, Isocrates and (by way of supplement) Dinarchus; _On the
admirable Style of Demosthenes_ ([Greek: Peri tes lektikes Demosthenous
deinotetos]); and _On the Character of Thucydides_ ([Greek: Peri tou
Thoukydidou charakteros]), a detailed but on the whole an unfair
estimate. These two treatises are supplemented by letters to Cn.
Pompeius and Ammaeus (two).

Complete edition by J. J. Reiske (1774-1777); of the _Archaeologia_ by
A. Kiessling and V. Prou (1886) and C. Jacoby (1885-1891); Opuscula by
Usener and Radermacher (1899); Eng. translation by E. Spelman (1758).
A full bibliography of the rhetorical works is given in W. Rhys
Roberts's edition of the Three Literary Letters (1901); the same
author published an edition of the _De compositione verborum_ (1910,
with trans.); see also M. Egger, _Denys d'Halicarnasse_ (1902), a very
useful treatise. On the sources of Dionysius see O. Bocksch, "De
fontibus Dion. Halicarnassensis" in _Leipziger Studien_, xvii. (1895).

DIONYSIUS PERIEGETES, author of a [Greek: Periegesis tes oikoumenes], a
description of the habitable world in Greek hexameter verse, written in
a terse and elegant style. Nothing certain is known of the date or
nationality of the writer, but there is some reason for believing that
he was an Alexandrian, who wrote in the time of Hadrian (some put him as
late as the end of the 3rd century). The work enjoyed a high degree of
popularity in ancient times as a school-book; it was translated into
Latin by Rufus Festus Avienus, and by the grammarian Priscian. The
