Extract

The reputation Theologoumena Arithmeticae has acquired is largely that of being an odd, and frequently opaque, compilation of arithmological lore. As a sourcebook for this aspect of the Pythagorean tradition it is, of course, invaluable. However, its poor reputation is increased, and its historical value lessened, by the depredations time has wrought on the text. ThA was never great prose: it is a compilation, largely from the lost Theologoumena Arithmeticae of Nicomachus of Gerasa and from Anatolius' Peri Dekados; and the text which cannot be safely or conjecturally assigned to these two sources often reads like little more than the written-up notes of some student. However, the treatise contains passages of considerable lucidity, within the context of its peculiar framework.

1 I am grateful to the anonymous referee, to Professor John Dillon, and to the Editors for help both general and particular.

2 By F. Ast (Leipzig, 1817) and V. de Falco (Leipzig, 1922; Teubner series). De Falco's edition gained extra notes by U. Klein in 1975. The only edition prior to Ast's was Wechel's, C.editio princeps (Paris, 1543)Google Scholar, which de Falco dismisses as ‘nullius pretii’. Ast's edition was based on theeditio princeps, but has the saving grace of a number of judicious emendations. De Falco, however, was the first to undertake a thorough collation of the manuscripts.

3 The bibliography is not extensive: the only substantial item to add to Klein's bibliography on pp. xviii–xxiii of the Teubner is Tarán, L., Speusippus of Athens (Leiden, 1981), 140–2, 257–98CrossRefGoogle Scholar.

4 Of course, the opacity of the subject matter means that in emending the text one has to beware of emendations which are suggested merely by one's own incomprehension.

6 Oppermann (see previous note) contains the best analysis of the structure of ThA, as consisting of excerpts from various sources. Note, however, that Oppermann overlooks the excerptor's ὅτι at 71.13.

9 Heteromecic numbers are oblong numbers whose sides differ by a factor of 1. These were the type of oblong numbers with which the Pythagoreans were most impressed, because any heteromecic number is the sum of two equal triangular numbers, and is also the sum of successive even numbers.
