Dionysius in Harpers Dictionary of Classical Antiquities
Halicarnassensis or Halicarnasseus, an historian and critic, born at Halicarnassus in the first century B.C. We know nothing of his history beyond what he has told us himself. He states that he came to Italy at the termination of the civil war between Augustus and Antony (B.C. 29), and that he spent the following two-and-twenty years at Rome in learning the Latin language and in collecting materials for his history. He died at Rome, B.C. 7. The principal work of Dionysius is his work on Roman antiquities (Ῥωμαϊκὴ Ἀρχαιολογία), which commenced with the early history of the people of Italy and terminated with the beginning of the First Punic War, B.C. 265. It originally consisted of twenty books, of which the first ten remain entire. The eleventh breaks off in the year B.C. 312, but several fragments of the latter half of the history are preserved in the collection of Constantine Porphyrogenitus, and to these a valuable addition was made in 1816, by Mai, from an old MS. Besides, the first three books of Appian were founded entirely upon Dionysius, and Plutarch's biography of Camillus must also be considered as a compilation mostly taken from the Antiquitates Romanae, so that perhaps, upon the whole, we have not lost much of his work. The intention of the author in writing his history was to give the Greeks a more accurate and favourable idea than they had hitherto entertained of the Roman people and its civilization, for it had always fretted the Easterns to have been conquered by a race of mere "barbarians." The work is founded upon a very careful and thorough study of authorities, and is one of our chief sources of information upon ancient Roman history in its internal and external development. Good editions of the Antiquitates are those of Reiske, 6 vols. (Leipzig, 1774-76), Schwartz (Leipzig, 1877), and Jacoby 2 vols. (1885-88). The first edition in the original Greek was that of R. Stephanus (Paris, 1546).
Dionysius also wrote a treatise on rhetoric (Τέχνη Ρητορική); criticisms (Τῶν Ἀρχαίων Κρίσις） on the style of Thucydides, Lysias, Isocrates, Isaeus , Dinarchus, Plato, and Demosthenes; a treatise on the arrangement of words (Περὶ Συνθέσεως Ὀνομάτων); and some other short essays. The first complete edition of the entire works of Dionysius was that of Sylburg (Frankfort, 1586; reprinted at Leipzig, 1691). More recent editors of the rhetorical works are Gros (Paris, 1826) and Westermann.
Dionysius of Halicarnassus in Wikipedia
Dionysius of Halicarnassus (Greek: Διονύσιος Ἀλεξάνδρου Ἀλικαρνᾱσσεύς, Dionysios son of Aléxandros, of Halikarnassós, c. 60 BC–after 7 BC) was a Greek historian and teacher of rhetoric, who flourished during the reign of Caesar Augustus.
He went to Rome after the termination of the civil wars, and spent twenty-two years in studying the Latin language and literature and preparing materials for his history. During this period he gave lessons in rhetoric, and enjoyed the society of many distinguished men. The date of his death is unknown. It is commonly supposed he is the ancestor of Aelius Dionysius of Halicarnassus.
His great work, entitled Ῥωμαϊκὴ Ἀρχαιολογία (Rhōmaikē archaiologia, Roman Antiquities), embraced the history of Rome from the mythical period to the beginning of the First Punic War. It was divided into twenty books, of which the first nine remain entire, the tenth and eleventh are nearly complete, and the remaining books exist in fragments in the excerpts of Constantine Porphyrogenitus and an epitome discovered by Angelo Mai in a Milan manuscript. The first three books of Appian, and Plutarch's Life of Camillus also embody much of Dionysius.
His chief object was to reconcile the Greeks to the rule of Rome, by dilating upon the good qualities of their conquerors and also by arguing, using more ancient sources, that the Romans were genuine descendants (bοοκ 1,11) of the older Greeks . According to him, history is philosophy teaching by examples, and this idea he has carried out from the point of view of the Greek rhetorician. But he has carefully consulted the best authorities, and his work 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 (Τέχνη ῥητορική, Téchne rhētorikē), which is rather a collection of essays on the theory of rhetoric, incomplete, and certainly not all his work;
* The Arrangement of Words (Περὶ συνθέσεως ὀνομάτων, Perì synthéseōs onomátōn), treating of the combination of words according to the different styles of oratory;
* On Imitation (Περὶ μιμήσεως, Perì mimēseōs), 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 (Περὶ τῶν Ἀττικῶν ῥητόρων, Perì tôn Attikôn rhētórōn), which, however, only deal with Lysias, Isaeus, Isocrates and (by way of supplement) Dinarchus;
* On the Admirable Style of Demosthenes (Περὶ λεκτικῆς Δημοσθένους δεινότητος, Perì lektikês Dēmosthénous deinótētos); and
* On the Character of Thucydides (Περὶ Θουκυδίδου χαρακτῆρος, Perì Thoukydídou charaktêros).
The last two treatises are supplemented by letters to Gn. Pompeius and Ammaeus (two).
He is often cited as Dion. Halic. in print publications.
