Donatus is to be distinguished from Tiberius Claudius Donatus,
the author of a commentary (_Interpretationes_) on the Aeneid (of far
less value than that of Servius), who lived about fifty years later.

The best text of the _Ars_ and the commentaries upon it by Servius and
others is in H. Keil, _Grammatici Latini_, iv.; of the commentary on
Terence there is an edition by P. Wessner (1902, Teubner series), with
bibliography and full account of MSS. See generally E. A. Grafenhan,
_Geschichte der klassischen Philologie im Altertum_, iv. (1850); P.
Rosenstock, _De Donato, Terenti ... explicatore_ (1886); H. T.
Karsten, _De comm. Don. ad Terenti fabulas origine et compositione_
(Leiden, 1907). For the commentary of Tiberius Donatus see O. Ribbeck,
Prolegomena to Virgil, Grafenhan (as above), and V. Burkas, _De
Tiberii Claudii Donati in Aeneidem commentario_ (1889). The text will
be found in G. Fabricius's edition of Virgil (1561), ed. by H. George,
i. (1905 foll.).

DONAUWORTH, a town of Germany in the kingdom of Bavaria, on the left
bank of the Danube, at the confluence of the Wornitz, 25 m. N. of
Augsburg by rail and at the junction of lines to Ulm and Ingolstadt.
Pop. 5000. It is an ancient town and has several medieval buildings of
interest. Notable among its seven churches (six Roman Catholic) are the
Kloster-Kirche (monasterial), a beautiful Gothic edifice with the
sarcophagus of Maria of Brabant, and that of the former Benedictine
abbey, Heilig-Kreuz, with a lofty tower. Remarkable among secular
buildings are the Gothic town hall, and the so-called Tanz-haus, which
now includes both a theatre and a school. The industries embrace
machinery, brewing and saw-milling; the place is of some importance as a
river port, and the centre of a considerable agricultural trade.

Donauworth grew up in the course of the 11th and 12th centuries under
the protection of the castle of Mangoldstein, became in the 13th a seat
of the duke of Upper Bavaria, who, however, soon withdrew to Munich to
escape from the _manes_ of his wife Maria of Brabant, whom he had there
beheaded on an unfounded suspicion of infidelity. The town received the
freedom of the Empire in 1308, and maintained its position in spite of
the encroachments of Bavaria till 1607, when the interference of the
Protestant inhabitants with the abbot of the Heilig-Kreuz called forth
an imperial law authorizing the duke of Bavaria to inflict chastis
