The "Anonymous Philosophical Treatise" was preserved only in Armenian. It was published first half-a-century ago in Armenian and in Russian translation, but is barely known to western scholarship. Here a new edition is presented, prepared on computer, together with critical apparatuses, translation and commentary. A variety of tools for the study of the text are included: a concordance, a word list of the English translation, triliteral tables of Armenian - Greek - English technical terminology and more.
