The story of the discovery of the book here translated so resembles a romance as to appear like a flower in the dry and dusty field of patristic lore. A short treatise called Philosophumena, or "Philosophizings," had long been known, four early copies of it being in existence in the Papal and other libraries of Rome, Florence and Turin. The superscriptions of these texts and a note in the margin of one of them caused the treatise to be attributed to Origen, and its Editio princeps is that published in 1701 at Leipzig by Fabricius with notes by the learned Gronovius. As will be seen later, it is by itself of no great importance to modern scholars, as it throws no new light on the history or nature of Greek philosophy, while it is mainly compiled from some of those epitomes of philosophic opinion current in the early centuries of our era, of which the works of Diogenes Laertius and Aetius are the best known. In the year 1840, however, Mynoïdes Mynas, a learned Greek, was sent by Abel Villemain, then Minister of Public Instruction in the Government of Louis Philippe, on a I voyage of discovery to the monasteries of Mt. Athos, whence he returned with, among other things, the MS. of the last seven books contained in these volumes. This proved on investigation to be Books IV to X inclusive of the original work of which the text published by Fabricius was Book I, and therefore left only Books II and III to be accounted for.
