Bekker numbers, the standard form of reference to works in the Corpus Aristotelicum, are based on the page numbers used in the Prussian Academy of Sciences edition of the complete works of Aristotle (
Aristotelis Opera edidit Academia Regia Borussica, Berlin, 1831–1870). They take their name from the editor of that edition, the classical
philologist August Immanuel Bekker (1785–1871).
Fragments Surviving fragments of the many lost works of Aristotle were included in the fifth volume of Bekker's edition, edited by
Valentin Rose. These are not cited by Bekker numbers, however, but according to fragment numbers. Rose's first edition of the fragments of Aristotle was
Aristoteles Pseudepigraphus (1863). As the title suggests, Rose considered these all to be spurious. The numeration of the fragments in a revised edition by Rose, published in the
Teubner series,
Aristotelis qui ferebantur librorum fragmenta, Leipzig, 1886, is still commonly used (indicated by
R3), although there is a more current edition with a different numeration by
Olof Gigon (published in 1987 as a new vol. 3 in
Walter de Gruyter's reprint of the Bekker edition), and a new de Gruyter edition by
Eckart Schütrumpf is in preparation. For a selection of the fragments in English translation, see W. D. Ross,
Select Fragments (Oxford 1952), and
Jonathan Barnes (ed.),
The Complete Works of Aristotle: The Revised Oxford Translation, vol. 2, Princeton 1984, pp. 2384–2465. A new translation exists of the fragments of Aristotle's
Protrepticus, by Hutchinson and Johnson (2015). The works surviving only in fragments include the dialogues
On Philosophy (or
On the Good),
Eudemus (or
On the Soul),
On Justice, and
On Good Birth. The possibly spurious work,
On Ideas survives in quotations by
Alexander of Aphrodisias in his commentary on Aristotle's
Metaphysics. For the dialogues, see also the editions of
Richard Rudolf Walzer,
Aristotelis Dialogorum fragmenta, in usum scholarum (Florence 1934), and Renato Laurenti,
Aristotele: I frammenti dei dialoghi (2 vols.), Naples: Luigi Loffredo, 1987. Additionally, the
Constitution of the Athenians (Greek,
Athenaiōn Politeia; Latin,
Atheniensium Respublica) was not included in Bekker's edition because it was first discovered in 1879.
Printed editions Aristotle's works have been published in many printed editions, either as complete editions of all surviving writings or as partial collections. English complete editions include: • W. D. Ross translation, 12 vols. (Oxford University Press, 1955) • Jonathan Barnes translation, 2 vols., 1984 == Notes ==
