Iohannis Scotti Annotationes in Marcianum THE MEDIAEVAL ACADEMY OF AMERICA PUBLICATION No. 34 IOHANNIS SCOTTI ANNOTATIONES IN MARCIANUM IOHANNIS SCOTTI ANNOTATIONES IN MARCIANUM EDITED BY CORA E. LUTZ Wilson College THE MEDIAEVAL ACADEMY OF AMERICA CAMBRIDGE, MASSACHUSETTS 1939 The publication of this book was made possible by grants of funds to the Academy from the Carnegie Corporation of New Tork and the American Council of Learned Societies. COPYRIGHT BY THE MEDIAEVAL ACADEMY OF AMERICA '939 Printed in U. S. A. PUNTED BY THE WAVISLY FKES3, INC. BALTIMORE, MARYLAND PREFACE EDIAEVALISTS have long felt the need for an edition of the M only work of John the Scot which has hitherto remained un- published, his commentary on the De nuptiis Philologiae et Mercurii of Martianus Capella. I first became interested in this problem while a student at the Yale Graduate School. There, under the guidance of Professor E. T. Silk, I made a study of the ninth-century commentaries on the seven liberal arts with especial reference to John the Scot, and presented it, together with a critical edition of four books of his commen- tary, as a dissertation for the doctor's degree. Since then, I have com- pleted the text, and have incorporated, with some revision, the pertinent conclusions of the earlier study into the introduction to the present edi- tion. I have taken the opportunity to suggest a few of the interesting problems which a consideration of the commentary has brought to my attention, although my main purpose has always been simply to make available this important treatise. Constantly, during the course of my work, I have taken advantage of the knowledge and interest of Professor Silk. Professor Rand has been very kind in encouraging the project. The Bibliotheque Nationale gave generous permission to have the manuscript of the commentary photo- graphed. The librarians of Yale University, Trini ty College, and Wilson College have been gracious in cooperating with me in my research. The publication of the edition has been most generously undertaken by the Mediaeval Academy of America with the assistance of the Carnegie Corporation of New York and the American Council of Learned Societies.

HISTORY AND AUTHORSHIP REEMINENT among the Irish scholars who made important P contributions to the intellectual life of Europe in the ninth century stands John the Scot. A long series of studies, from the early edition of the De divisione naturae made by Thomas Gale1 down to the recent exhaustive treatment of Cappuyns,2 have been successful in solving a great many of the problems connected with the life and writings of this great thinker. Yet until comparatively recently one of his works, a commentary on the De nuptiis Philologiae et Mercurii of Martianus Capella, was almost unknown.8 It is this commentary, entitled Annota- tiones in Marcianum in the unique manuscript, which I have undertaken to edit.* 1 Oxford, 1681. •M. Cappuyns, Jean Scot £riglne, sa vie, son oeuvre, sa pensie (Louvain, 1933). This book contains a very complete bibliography of John the Scot. 1 Some others of his philological works have suffered similar neglect. The commentaries on the Opuscula sacra of Boethius were first brought to light by Rand in 1906 ('Johannes Scottus,' Quellen und Untersuchungen zur lateinhchen Philologie des Mittelalters, 1). Since then, Cappuyns ('Le plus ancien commentaire des Opuscula Sacra et son origine,' Recherches de Thiologie ancienne et tnldilvale, 111 [1931], 237-272) has made an impressive case for the identification of the work as that of Remigius, but Rand maintains his original position ('The Supposed Commentary of John the Scot on the Opuscula Sacra of Boethius,' RSvue Nioscolastique, xxxvi [1934], 67-77). The question of the authorship of the Excerpta Macrobii de differentia et societatibus Graeci Latinique verbi is still being debated. Cf. P. G. Thery, 'Scot £rigene, Traducteur de Denys, 'Bulletin Du Cange, vi (1931), 217-218; J. Sandys, History of Classical Scholarship (3rd ed., Cambridge, 1921), 1, 495; H. Keil, Grammatici Latini (Leipzig, 1878), v, 595; L. Traube, 'O Roma Nobilis,' Abhandlungen der koniglich bayerischen Akademie der Wissenschaften, Philosophisch-philologische und historische Klasse, xix (1892), 355; M. R. James, Cambridge Medieval History, m, Ch. 20, p. 525; F. Vernet, Dictionnaire de Thfologie catholique (Paris, 1913), v, 409. M. Melandre ('Iepa ou Scot Erigene,' Archives a"His- toire doctrinale et littiraire du moyen age, vi [1931], 277-286) would make John the Scot the author of some glosses on the Jsagogae of Porphyrius which are ascribed to the unidentified Iepa. Recently E. T. Silk has presented very convincing evidence to support the thesis that an important anony- mous commentary on the Consolatio Philosophiae of Boethius is the work of John the Scot. Cf. Saeculi noni auctoris in Boetii Consolationem Philosophiae commentarius, Papers and Monographs of the American Academy in Rome, ix (1935), xxvii-1. 4 There is no mention of John the Scot's commentary on Martianus Capella in any of the sources. The little information that has been preserved relevant to the subject serves only to indicate that it is not improbable that the Irish scholar should have written glosses on the De nuptiis. For instance, one sentence in a letter by an unknown student who calls himself A to his master E, written sometime between the years 862 and 875, vouches for John the Scot's pursuit of grammar. He says: 'Imitatote etiam ... qualiter cantetur apud vestrates in responsorio "Domine pater," et "animo" (vel "animae") "inreverenti et infrunito" (aut "infronito" sive "infrodito") antepenultimo acuto secundum doctrinam Iohannis Scotti' (E. Dummler, 'Epistulae variorum inde a saeculo nono medio ix x Introduction The history of our knowledge of the commentary is very brief. It began in 1849, when Cardinal Pitra happened upon a manuscript of Mar- tianus Capella with scholia. He was led to the conclusion that the glosses originated with John the Scot. H. Floss, editor of the monu- mental edition of 1853 of the works of John the Scot, expressed his opinion that an anonymous commentary in a Paris manuscript, Bibli- otheque Nationale, jonds lat., MS 12960 (which will hereafter be called C for Corbeiensis),1 would bear investigation, since he suspected that the work could be identified as that of the Irish philosopher.2 Quite unaware of Floss' acquaintance with the manuscript, but defiant of the judgment of earlier scholars that no commentary of John the Scot existed,* Haureau made a thorough investigation of the subject. At last, in the Bibli- otheque Nationale, in the same ninth-century manuscript, C, which had been referred to by Floss, he came upon the anonymous commentary on Martianus Capella, and immediately set out to prove it the work of John the Scot.4 At that time a superficial study had been made of some three or four copies of a Martianus commentary written by a young contemporary of the Irishman, Remigius of Auxerre. From these glosses, which seem to be little more than an amplified copy of the older commentary, Haureau derived three proofs for the identity of John the Scot's commentary. On folio 27' of B.N.lat. 8674 °ftne Remigius 5 commentary he found the gloss: 'HEUS vocantis adverbium est. Joannes Scotus HEUS UBI ES resolvebat.' On folio 697 of the anonymous commen- usque ad mortem Karoli II imperatoris collectae,' Monumenta Germaniae Hislorica, Epistulae, vi, 184). In a record of the bishops of Auxerre, given in Gallia Christiana, one finds the following entry in the account of Wibaudus, bishop in the year 879: 'Nobilissimus parentibus Leutfrido atque Doda in civitate Cameracensi satus Wibaudus, adhuc juvenis Johanni Scoto, per Gallias magistro quam famosissimo, traditus est erudiendus, sub quo divinis aeque ac humanis disciplinis apprime fuit informatus' (D. de Sainte-Marthe, Gallia Christiana, XII, 277, 278). Of far greater significance, however, is a charge made against John the Scot by Prudentius, bishop of Troyes, in the course of his great denunciation of the treatise De praedestinatione. Instead of following the Scriptures and the Fathers, the Irishman, Prudentius maintains, made himself adept in the wiles of the rhetoricians and at last became inextricably enmeshed in the labyrinth of error through Martianus Capella: 'Nam ille tuus Capella, exceptis aliis, vel maxime te in hunc labyrinthum induxisse creditur, cujus meditatione magis quam veritati evangelicae animum appulisti. Quin etiam cum legeres beati Augustini libros, quos De Civitate Dei adversus paganorum fallacissimas falsissimasque opiniones mirabili affluentia digessit, invenisti eum posuisse ac destruxisse quaedam ex libris Varronis, quibus, quoniam Capellae tuo consona videbantur, potius assentiri quam veridici Augustini allegationibus fidem adhibere delegisti' (J. Migne, Patrologia Latina, cxv, 1294). 1 The history of this ninth-century manuscript, originally from Corbie, is given below. * Cf. Migne, P. L., cxxn, xviii, xix. • E.g., J. Fabricius, Bibliotheca Latina mediae et infimae aetatis, iv, 407: 'Omitto tanquam incerta vel alii tribuenda Joanni—Commentaries in Martianum Capellam.' * B.

    STAR OF THE WEEK: THUBAN The star Thuban in the constellation Draco (the Dragon) was the North Pole Star some 5,000 years ago, when the Egyptians were building the pyramids. Thuban is not a particularly bright star. At magnitude 3.7 and known as alpha draconis it is not even the brightest star in its constellation. What is Thuban’s connection with the pyramids of Egypt? Among the many mysteries surrounding Egypt’s pyramids are the so-called “air shafts” in the Great Pyramid of Giza. These narrow passageways were once thought to serve for ventilation as the The Great Pyramid of Giza, an enduring monument of ancient pyramids were being built. In the 1960s, though, Egypt. Egyptologists believe that it was built as a tomb for fourth dynasty Egyptian Pharaoh Khufu around 2560 BC the air shafts were recognized as being aligned with stars or areas of sky as the sky appeared for the pyramids’ builders 5,000 years ago. To this day, the purpose of all these passageways inside the Great Pyramid isn’t clear, although some might have been connected to rituals associated with the king’s ascension to the heavens. Whatever their purpose, the Great Pyramid of Giza reveals that its builders knew the starry skies intimately. They surely knew Thuban was their Pole Star, the point around which the heavens appeared to turn. Various sources claim that Thuban almost exactly pinpointed the position of the north celestial pole in the This diagram shows the so-called air shafts in the Great year 2787 B.C.

  • New Atmospheric Parameters and Spectral Interpolator for the MILES Cool Stars Kaushal Sharma1,2,3, Philippe Prugniel1,2, and Harinder P

The full spectrum fitting of stellar spectra against a library of empirical spectra is a well-established approach to measure the atmospheric parameters of FGK stars with a high internal consistency. Extending it towards cooler stars still remains a challenge. Aims. We address this question by improving the interpolator of the Medium-resolution INT Library of Empirical Spectra (MILES) library in the low effective temperature regime (Teff < 4800 K), and we refine the determination of the parameters of the cool MILES stars. Methods. We use the ULySS package to determine the atmospheric parameters (Teff,logg and [Fe/H]), and measure the biases of the results with respect to our updated compilation of parameters calibrated against theoretical spectra. After correcting some systematic effects, we compute a new interpolator that we finally use to redetermine the atmospheric parameters homogeneously and assess the biases. Results. Based on an updated literature compilation, we determine Teff in a more accurate and unbiased manner compared to those determined with the original interpolator.

  • Dhruva the Ancient Indian Pole Star: Fixity, Rotation and Movement
    Indian Journal of History of Science, 46.1 (2011) 23-39 DHRUVA THE ANCIENT INDIAN POLE STAR: FIXITY, ROTATION AND MOVEMENT R N IYENGAR* (Received 1 February 2010; revised 24 January 2011) Ancient historical layers of Hindu astronomy are explored in this paper with the help of the Purân.as and the Vedic texts. It is found that Dhruva as described in the Brahmân.d.a and the Vis.n.u purân.a was a star located at the tail of a celestial animal figure known as the Úiúumâra or the Dolphin. This constellation, which can be easily recognized as the modern Draco, is described vividly and accurately in the ancient texts. The body parts of the animal figure are made of fourteen stars, the last four of which including Dhruva on the tail are said to never set. The Taittirîya Âran.yaka text of the Kr.s.n.a-yajurveda school which is more ancient than the above Purân.as describes this constellation by the same name and lists fourteen stars the last among them being named Abhaya, equated with Dhruva, at the tail end of the figure. The accented Vedic text Ekâgni-kân.d.a of the same school recommends observation of Dhruva the fixed Pole Star during marriages. The above Vedic texts are more ancient than the Gr.hya-sûtra literature which was the basis for indologists to deny the existence of a fixed North Star during the Vedic period. However the various Purân.ic and Vedic textual evidence studied here for the first time, leads to the conclusion that in India for the Yajurvedic people Thuban (α-Draconis) was Dhruva the Pole Star c 2800 BC.

  • About the Foroughi Cup and About the Seven Planets in the Ancient World
    Archaeoastronomy and Ancient Technologies 2018, 6(2), 31–37; http://aaatec.org/art/a_cm2 www.aaatec.org ISSN 2310-2144 About the Foroughi Cup and about the seven planets in the Ancient World Mario Codebò 1, Henry De Santis 2 1 Archeoastronomia Ligustica, S.I.A., SAIt, Genoa, Italy; E-Mail: [email protected] 2 Archeoastronomia Ligustica, S.I.A., SAIt, Genoa, Italy; E-Mail: [email protected] Abstract The Foroughi Cup is an artefact of the 8th century BC of Aramaic cultural context, inside which images of stars and constellations are reproduced. In this study of ours we start from the conclusions reached by Amadasi Guzzo and Castellani in their two works of 2005 and 2006 and we add some further considerations and identifications. We then explain the hypothesis that some cultures of the Ancient World include seven planets, excluding the Moon and the Sun, because Mercury and Venus, always visible only at dawn or at sunset, were perhaps considered four different planets. Finally, we propose the thesis that their evil character depends, as for every new star (novae, supernovae, comets, etc.), on the fact that they alter the synchrony of the cosmos with their variable motion (variable declination heaven bodies). Keywords: Foroughi Cup, planets, Moon, Sun, Aramaic culture. The Foroughi Cup The Foroughi Cup is a bronze artefact (fig. 1), dated to the first half of the 1st millennium BC, containing in its concave interior a representation of the celestial vault and seven very small Aramaic inscriptions, only three of which are quite legible: ŠMŠ = Sun (above the representation of the Sun, in which a lion's head is also engraved); ŠHR = Moon (above the representation of the crescent of the Moon); hypothetically R'Š ŠR' = Head of the Bull (above the bucranium).

  • A Brief History of Beiji 北极 (Northern Culmen), with an Excursus on the Origin of the Character Di 帝”
    DRAFT OF WORK IN PROGRESS: NOT FOR CIRCULATION OR CITATION “A Brief History of Beiji 北极 (Northern Culmen), with an Excursus on the Origin of the Character di 帝” David W. Pankenier Lehigh University Abstract: In ancient Chinese astral lore, the imperial nomenclature associated with the circumpolar stars in the Palace of Purple Tenuity 紫微垣 points to the crucial importance of the north-pole in astrological, calendrical, and spiritual contexts. But preoccupation with this numinous region has a history dating back far earlier than the Qin and Han empires. This paper briefly surveys what is known about the pre-imperial history of the region of the ‘Northern Culmen,’ with particular reference to spiritual and metaphysical conceptions concerning the Northern Dipper, and to the void at the pivot of the heavens, where there was no prominent pole star throughout much of the formative period of classical Chinese civilization. The discussion concludes with a hypothesis about possible astral origins of the ancient form of the character used to denote the High God di 帝. Chinese preoccupation with astronomical orientation has a very long history. Archaeological evidence from the 5th millennium BCE Neolithic cultures of North China shows that burials and dwellings were already being oriented with particular attention to the diurnal and seasonal variations in the Sun’s position.1 With the beginning of the Bronze Age in the early 2nd millennium BCE and the inception of early state formation, such concepts had progressed to the point where ritually and politically important structures were uniformly quadrilateral in shape and cardinally oriented, with the longitudinal axis aligned with varying precision in a north-south direction.2 Palatial structures and royal tombs from the earliest dynastic states in the 2nd millennium BCE, that is, Xia,3 Shang, and Zhou, consistently display such orientation.

  • Extrasolar Planets and Their Host Stars
    Kaspar von Braun & Tabetha S. Boyajian Extrasolar Planets and Their Host Stars July 25, 2017 arXiv:1707.07405v1 [astro-ph.EP] 24 Jul 2017 Springer Preface In astronomy or indeed any collaborative environment, it pays to figure out with whom one can work well. From existing projects or simply conversations, research ideas appear, are developed, take shape, sometimes take a detour into some un- expected directions, often need to be refocused, are sometimes divided up and/or distributed among collaborators, and are (hopefully) published. After a number of these cycles repeat, something bigger may be born, all of which one then tries to simultaneously fit into one’s head for what feels like a challenging amount of time. That was certainly the case a long time ago when writing a PhD dissertation. Since then, there have been postdoctoral fellowships and appointments, permanent and adjunct positions, and former, current, and future collaborators. And yet, con- versations spawn research ideas, which take many different turns and may divide up into a multitude of approaches or related or perhaps unrelated subjects. Again, one had better figure out with whom one likes to work. And again, in the process of writing this Brief, one needs create something bigger by focusing the relevant pieces of work into one (hopefully) coherent manuscript. It is an honor, a privi- lege, an amazing experience, and simply a lot of fun to be and have been working with all the people who have had an influence on our work and thereby on this book. To quote the late and great Jim Croce: ”If you dig it, do it.
