gen
Sonnenkreise der Alten_ (1863), and several papers which he published in
the _Transactions of the Berlin Academy_. Bockh also occupied himself
with philosophy. One of his earliest papers was on the Platonic doctrine
of the world, _De Platonica corporis mundani fabrica_ (1809), followed
by _De Platonico Systemate Caelestium globorum et de vera Indole
Astronomiae Philolaice_ (1810), to which may be added _Manetho und die
Hundsternperiode_ (1845). In opposition to Otto Gruppe (1804-1876), he
denied that Plato affirmed the diurnal rotation of the earth
(_Untersuchungen uber das kosmische System des Platon_, 1852), and when
in opposition to him Grote published his opinions on the subject (Plato
and the Rotation of the Earth) Bockh was ready with his reply. Another
of his earlier papers, and one frequently referred to, was _Commentatio
Academica de simultate quae Platoni cum Xenophonte intercessisse fertur_
(1811). Other philosophical writings were _Commentatio in Platonis qui
vulgo fertur Minoem_ (1806), and _Philolaos' des Pythagoreers Lehren
nebst den Bruchstucken_ (1819), in which he endeavoured to show the
genuineness of the fragments.

Besides his edition of Pindar, Bockh published an edition of the
Antigone of Sophocles (1843) with a poetical translation and essays. An
early and important work on the Greek tragedians is his _Graecae
Tragoediae Principum ... num ea quae supersunt et genuina omnia sint et
forma primitiva servata_ (1808).

The smaller writings of Bockh began to be collected in his lifetime.
Three of the volumes were published before his death, and four after
(_Gesammelte kleine Schriften_, 1858-1874). The first two consist of
orations delivered in the university or academy of Berlin, or on
public occasions. The third, fourth, fifth and sixth contain his
contributions to the _Transactions of the Berlin Academy_, and the
seventh contains his critiques. Bockh's lectures, delivered from
1809-1865, were published by Bratuschek under the title of
_Encyclopadie und Methodologie der philologischen Wissenschaften_ (2nd
ed, Klussmann, 1886). His philological and scientific theories are set
forth in Elze, _Uber Philologie als System_ (1845), and Reichhardt,
_Die Gliederung der Philologie entwickelt_ (1846). His correspondence
with Ottfried Muller appeared at Leipzig in 1883. See Sachse,
