Pseudo-Elias

Pseudo-Elias (?), also called Pseudo-David, was the author of a set of lectures on logic written in Ancient Greek that form a commentary on Porphyry's Isagoge. The commentary, except for the first seven lectures, survives in a number of medieval manuscripts.

Identity
The manuscripts identify the author of the commentary variously as either Elias or David, two other Neoplatonist commentators on Aristotle. However, modern scholars doubt these ascriptions based on comparisons to those authors' other extant works, and so the author is generally known as Pseudo-Elias or Pseudo-David.

The author of the commentary was probably active at Constantinople, or possibly Thessaloniki, some time before the closure of the University of Constantinople in 726, but probably closer to 600, and no earlier than the late sixth century, after Olympiodorus and Elias. Based on the name attributed to him, and the historical adoption of Neoplatonism by Christian philosophers in the Byzantine empire in the late 7th century, the author is generally identified as a Christian.

Although he was not working in Alexandria or Athens, he may have been educated in Alexandria or by an Alexandrian, as the work shows the influence of the school of Ammonius Hermiae. He may also have been a student of Stephanus of Alexandria, and some scholars have even identified Stephanus as the author of the Commentary.

Modern scholars have debated the relationship between Pseudo-Elias and the three other extant Neoplatonic commentaries on the Isagoge that were written by Ammonius, Elias, and David. Miroslav Marcovich argues that Elias depends on Ammonius, David on Elias and Ammonius, and Pseudo-Elias on Elias and David. Christian Wildberg also accepts Pseudo-Elias's dependence on both Elias and David. Henry Blumenthal, however, argues that Pseudo-Elias depends only on Elias and that David in turn depends on him.

Some modern scholars have suggested that the author was a physician by profession giving introductory lectures on logic, given that although the philosophical content of the work is rather weak, the author demonstrates special interest in Ancient Greek medicine and especially in the writings of Galen.

Lectures on Porphyry's Isagoge


The Commentary is divided into 51 lectures, which can be divided into three sections:
 * Lectures 1-23, of which the first seven are missing in all manuscripts, form the prolegomena to philosophy.
 * Lectures 24-27 are a prolegomena to the Isagoge
 * Lectures 28-51 form the commentary proper.

The division of the work into separate lectures follows the practice common to Neoplatonic commentaries following Olympiodorus, and the content of both introductions and the commentary itself are "substantially the same" as in David's Commentary on the Isagoge, but the commentary itself is the most original part of the work.

As philosophy, the commentary is rather weak. The weakness of the argumentation may, in some cases, be the fault of the transcriptionist who recorded the lectures, but the misunderstandings of Aristotle and ignorance of Plato belong to the lecturer.

Manuscript tradition
Three manuscripts of the sixteenth century contain almost the complete text, minus the first seven lectures. These fuller copies name the philosopher David, which may be a guess of the scribes based on style.

 * Munich, Bayerische Staatsbibliothek, gr. 399, at folios 162r–268r
 * Turin, Biblioteca Nazionale Universitaria, C. II. 7 (gr. 108), at folios 9r–138r

Two manuscripts of the fourteenth century contain excerpts, which may have been made from complete texts that were not missing the first seven lectures. These manuscripts name the author as Elias.
