His model explained • variation in brightness of planets • changes in angular speed Ptolemy (AD 100 – c. 170): Almagest summarized ancient ideas about solar system. He himself proposed “equant point”: eccentric point about which planet moved with constant angular speed. Not true uniform circular motion, but explained data better. Ptolemaic universe (Equant point suppressed) • Note: this picture puts planets at a distance relative to Earth corresponding to our modern knowledge, but Ptolemaic system did not predict order of planets (or care!) • Exception: inner planets had to have orbits that kept them between Earth and Sun • Why epicycles? Not asked. Clicker quickies Q1: Ptolemy’s model explained retrograde motion of the planets. This means that A. Some planets moved clockwise while others moved counterclockwise along their orbits B. Some planets moved outside the plane of the ecliptic C. Some planets were observed to stop in the sky, move apparently backwards along their path, forward again D. -
Philoponus on Topos
Philoponus on τόπος. Redefining Place in Late Antiquity D i s s e r t a t i o n zur Erlangung des akademischen Grades Doctor philosophiae (Dr. phil.) eingereicht an der Philosophischen Fakultät I der Humboldt-Universität zu Berlin und verteidigt am 25. October 2013 von Ioannis Papachristou Der Präsident der Humboldt-Universität zu Berlin Prof. Dr. Jan-Hendrik Olbertz Der Dekan der Philosophischen Fakultät I Prof. Michael Seadle, PhD Gutachter Erstgutachter: Prof. Dr. Christoph Helmig Zweitgutachter: Prof. Dr. Christian Wildberg The dissertation attempts to interpret afresh, on the one hand, the form, methodology and structure of Philoponus’ commentary on the Physics and, on the other hand, to study in depth his theory of place (topos). The book extends over five chapters and includes a preface, an epilogue and a bibliography. Philoponus attempts a double determination of place. He distinguishes between the place which is void, three-dimensional extension that is ontological different from bodies, and the concept of place that is filled by bodies. Philoponus wishes to redefine the relationship between place and body and he underlines the ontological difference that a bodiless extension should have from a bodily extension. The thesis also focuses on Philoponus’ critique of Aristotle’s definition of place and the Peripatetic tradition (Eudemus, Themistius) regarding the place of the heavens. The book concludes that, Philoponus’ strategy in the digressions of the commentary, but also in certain parts of his exegeses, can be seen in three stages: first, he repudiates the cogency of Aristotle’s and Themistius’ critique to the concept of local extension; second, he attacks the Aristotelian definition of place by showing its weaknesses and inconsistencies with the nature of things; and third, he establishes his own theory of place. -

Iamblichus and Julian‟s “Third Demiurge”: A Proposition Adrien Lecerf Ecole Normale Supérieure, Paris, France [email protected] ABSTRACT. In the Emperor Julian's Oration To the Mother of the Gods, a philosophical interpretation of the myth of Cybele and Attis, reference is made to an enigmatic "third Demiurge". Contrary to a common opinion identifying him to the visible Helios (the Sun), or to tempting identifications to Amelius' and Theodorus of Asine's three Demiurges, I suggest that a better idea would be to compare Julian's text to Proclus' system of Demiurges (as exposed and explained in a Jan Opsomer article, "La démiurgie des jeunes dieux selon Proclus", Les Etudes Classiques, 71, 2003, pp. -
Pythagorean Music in Boethius's Consolation of Philosophy
32 RAMIFY 8.1 (2019) “How Pythagoras Cured by Music”: Pythagorean Music in Boethius’s Consolation of Philosophy KIMBERLY D. HEIL Interpretive schemata for reading Boethius’s Consolation of Philosophy are plentiful. Some of the more popular of those schema read the work along the divided line from Plato’s Republic, taking as programmatic the passage from Book Five in which Boethius discusses the ways in which man comes to know through sensation first, then imagination, then reason, and finally understanding.1 Others read the work as Mneppian Satire because of its prosimetron format. Some scholars study character development in the KIMBERLY D. HEIL is a PhD candidate in Philosophy at the Institute of Philosophic Studies at the University of Dallas; she received a BA in Philosophy from the University of Nebraska at Kearney and an MA in Philosophy from the University of South Florida. She is currently a Wojtyła Graduate Teaching Fellow at the University of Dallas, where she teaches core curriculum philosophy classes. She is writing a dissertation on the relationship between philosophy and Christianity in Augustine of Hippo’s De Beata Vita. The title of this piece is taken from a section subtitle in the work The Life of Pythagoras by the second-century Neopythagorean Iamblichus. 1 See, for instance, McMahon, Understanding the Medieval Meditative Ascent, 215. He references two other similar but competing interpretations using the same methodology. “How Pythagoras Cured by Music” : HEIL 33 work as it echoes Platonic-style dialogues. Still others approach the work as composed of several books, each representing a distinct school of philosophy.2 Furthermore, seeing it as an eclectic mixture of propositions from various schools of philosophy re-purposed and molded to suit Boethius’s own needs, regardless of the literary form and patterns, is commonly agreed upon in the secondary literature. -
Automatic Action in Plotinus
Created on 26 November 2007 at 17.13 hours page 373 AUTOMATIC ACTION IN PLOTINUS JAMES WILBERDING 1. Introduction Plotinus scholars have recently called attention to a kind of action in the sensible world, which one could call ‘spontaneous’ or ‘automatic’ action, that is supposed to result automatically from the contemplation of the intelligible.1 Such action is meant to be opposed to actions that result from reason, calculation, and plan- ning, and has been put to work to provide a way for Plotinus’ sage to act, and in particular to act morally, without compromising his ã James Wilberding 2008 A version of this paper was presented at the Katholieke Universiteit Leuven in 2006, where it received a helpful discussion. For comments and suggestions I am par- ticularly indebted to Peter Adamson, Julie Cassiday, Christoph Helmig, Christoph Horn, Jan Opsomer, David Sedley, and Carlos Steel. I have also profited greatly from a reading group held in autumn 2005 at King’s College London on Ennead 3. 8 with Peter Adamson, Verity Harte, M. M. McCabe, and others. I would like to thank Williams College and the Humboldt-Stiftung for funding the research leave during which this paper was written, and Andreas Speer for welcoming me into the Thomas-Institut for this period. 1 e.g. A.

A Correspondent of Iamblichus TD Barnes
A Correspondent of Iamblichus Barnes, T D Greek, Roman and Byzantine Studies; Jan 1, 1978; 19, 1; ProQuest pg. 99 A Correspondent of Iamblichus T. D. Barnes HE CORRESPONDENCE of the emperor Julian, as transmitted in T various manuscripts, includes six letters addressed to the philosopher Iamblichus (Epp. 181, 183-187 Bidez-Cumont).l Since Iamblichus died before Julian was born, it is impossible that the emperor could ever have written to the philosopher. On the other hand, the letters do not read like the productions of a deliberate forger, nor do they simulate an emperor's authorship. On internal criteria, one would naturally interpret them as letters from an absent pupil to his former teacher. Accordingly, Franz Cumont argued that these six letters, together with another two (Epp. 180, 182) and possibly another ten (Epp. 188-197), are genuine letters, which were mistakenly attributed to the emperor Julian because their real author was Julianus of Caesarea, otherwise known as a sophist active in Athens in the early fourth century.2 Joseph Bidez subsequently amplified Cumont's arguments into a study of Iamblichus and his circle which remains, after more than fifty years, the standard account of the philosopher's life. 3 The central thesis of Cumont and Bidez seems as secure as the nature of the case admits, but their deductions from it need some important modifications. First, as Bidez and Cumont later realised, a sophist from Caesarea in Cappadocia (Suda I 435) cannot be supposed to have written these letters,4 for one of the letters to Iamblichus states that writer and recipient share the same fatherland (Ep. -
375 A. Mark Smith A. Mark Smith's Lucidly Written Account of The
book reviews Early Science and Medicine 21 (2016) 375-377 375 A. Mark Smith From Sight to Light: The Passage from Ancient to Modern Optics (Chicago: University of Chicago Press, 2015), pp. 480, $45.00 (cloth), ISBN 978 02 261 7476 1. A. Mark Smith’s lucidly written account of the history of optics, from the an- cient world to the late seventeenth century, is comprehensive in scope and presents a radical break from the traditional narrative of the role medieval per- spectiva played in Johannes Kepler’s visual theory. Smith argues in a convinc- ing manner that while Kepler was clearly aware of perspectival sources, several elements of his thinking, and particularly his decision to accept the inverted retinal image as the principal means of sight, indicates a revolutionary turn away from the medieval tradition. This “Keplerian turn” had both analytic and epistemological elements, which Smith details at great length in his penulti- mate chapter. Smith characterizes his work as a “revamping” of David Lind- berg’s equally grand historical narrative Theories of Vision from Al-Kindi to Kepler, first published in 1976 (p. 4). In many ways this is an accurate assess- ment, barring Smith’s significant argumentative departure from the idea that Kepler relied on a firm grounding in perspectiva. Smith shifts his focus away from solely technical descriptions of optical theories, which can be found in Lindberg, and provides a much more inclusive history that treats the im- portance of psychological and theological texts in the development of perspec- tiva. Smith begins his narrative by exploring the earliest roots of perspectiva in the ancient sources, particularly Plato, Aristotle, Galen, Euclid, and Ptolemy. -
Iamblichus' Exegesis of Parmenides'
IAMBLICHUS’ EXEGESIS OF PARMENIDES’ HYPOTHESES AND HIS DOCTRINE OF DIVINE HENADS Svetlana Mesyats 1. Henads and the Problem of the Transcendent First Principle The question about the First Principle is one of the central problems of Neoplatonism as well as that of every monistic system of philosophy, that considers the world as a creation of a single divine Cause. The problem here is the following: the absolutely transcendent and self-su cient Principle does not need to cause anything outside itself, because to be transcendent means to be entirely independent from all the rest. But a principle, which is entirely independent from its own efects, cannot be a cause, since causality presupposes some relationship between the causative principle and its efects. Consequently we are faced with a dilemma: either to de ne some principle as a cause, so that it depends by nature on its own efects and is no longer transcendent; or to de ne it as transcendent, so that it cannot be a cause. In the history of Platonic philosophy there were many eforts to solve this dilemma. In one of his treatises Plotinus described the One as a “productive power of all things” (δύναµις τῶν πάντων)1 and so to some extent introduced into the Absolute all the plurality of its efects, at least in the mode of potency, power. Plotinus’ pupil Porphyry abandoned the idea of the transcendent Principle and identi ed the supreme One with Being.2 Iamblichus after him proposed the theory of “two” Ones, rst of which he thought to be completely inefable and inexpressible, whereas the second one he understood as a cause in the true sense of the word in so far as it 1 Plotinus, Enneads III, 8, 10, 1. -

Damian Caluori (Trinity University) Rhetoric and Platonism in Fifth-Century Athens There are reasons to believe that relations between Platonism and rhetoric in Athens during the fifth century CE were rather close.Z Both were major pillars of pagan cul- ture, or paideia, and thus essential elements in the defense of paganism against in- creasingly powerful and repressive Christian opponents. It is easy to imagine that, under these circumstances, paganism was closing ranks and that philosophers and orators united in their efforts to save traditional ways and values. Although there is no doubt some truth to this view, a closer look reveals that the relations be- tween philosophy and rhetoric were rather more complicated. In what follows, I will discuss these relations with a view to the Platonist school of Athens. By “the Platon- ist school of Athens” I mean the Platonist school founded by Plutarch of Athens in the late fourth century CE, and reaching a famous end under the leadership of Dam- ascius in 529.X I will first survey the evidence for the attitudes towards rhetoric pre- vailing amongst the most important Athenian Platonists of the time. -

Translated by Owen Goldin & Marije Martijn. Bloomsbury, 2012. Pp. vi + 217. Philoponus, On Aristotle: Physics 4.1-5. Translated by Keimpe Algra & Johannes van Ophuijsen. Bloomsbury, 2012. Pp. vii + 151. Philoponus, On Aristotle: Physics 4.6-9. Translated by Pamela Huby. Bloomsbury, 2012. Pp. vi + 138. Philoponus, On Aristotle: Meteorology 1.4-9,12. Translated by Inna Kupreeva. Bloomsbury, 2012. Pp. vii + 198. These four volumes constitute the most recent translations of Philoponus’ commentaries to appear in the Ancient Commentators on Aristotle series edited by Richard Sorabji. They also bring to completion the translation of Philoponus’ extant commentaries on Aristotle’s Posterior Analytics, Physics, and Book 1 of the Meteorology in the Ancient Commentators series, along with the majority of the texts of Philoponus edited in the Commentaria in Aristotelem Graeca. The exceptions are Philoponus’ commentaries on the Categories and Prior Analytics for which there are only currently limited plans (although a forthcoming joint volume of his commentary on Categories 1-5 along with his A Treatise on Whole and Parts is now planned for 2015). Since first appearing in hardcover, they are also now available both in paperback and eBook versions (a very welcome development for the series as a whole). Each of the four volumes supplies useful information for Philoponus’ approach and interpretation of Aristotle.
