  • “Savage and Deformed”: Stigma As Drama in the Tempest Jeffrey R
    “Savage and Deformed”: Stigma as Drama in The Tempest Jeffrey R. Wilson The dramatis personae of The Tempest casts Caliban as “asavageand deformed slave.”1 Since the mid-twentieth century, critics have scrutinized Caliban’s status as a “slave,” developing a riveting post-colonial reading of the play, but I want to address the pairing of “savage and deformed.”2 If not Shakespeare’s own mixture of moral and corporeal abominations, “savage and deformed” is the first editorial comment on Caliban, the “and” here Stigmatized as such, Caliban’s body never comes to us .”ס“ working as an uninterpreted. It is always already laden with meaning. But what, if we try to strip away meaning from fact, does Caliban actually look like? The ambiguous and therefore amorphous nature of Caliban’s deformity has been a perennial problem in both dramaturgical and critical studies of The Tempest at least since George Steevens’s edition of the play (1793), acutely since Alden and Virginia Vaughan’s Shakespeare’s Caliban: A Cultural His- tory (1993), and enduringly in recent readings by Paul Franssen, Julia Lup- ton, and Mark Burnett.3 Of all the “deformed” images that actors, artists, and critics have assigned to Caliban, four stand out as the most popular: the devil, the monster, the humanoid, and the racial other. First, thanks to Prospero’s yarn of a “demi-devil” (5.1.272) or a “born devil” (4.1.188) that was “got by the devil himself” (1.2.319), early critics like John Dryden and Joseph War- ton envisioned a demonic Caliban.4 In a second set of images, the reverbera- tions of “monster” in The Tempest have led writers and artists to envision Caliban as one of three prodigies: an earth creature, a fish-like thing, or an animal-headed man.

Möglichst viele solcher Darstel­ lungen und Vorkommen sollen hier zwar genannt werden (obschon dem Verfasser auch nicht annähernd alle bekannt wurden), wichtiger war aber ein Leitgedanke, der sowohl etwas vom Wesen des Gottes selbst spüren ließ als auch von der Eigenart derer, die ihn dargestellt oder in ihren Werken haben vorkommen lassen, und dieser Leitgedanke war etwa dieser: § 2 Renaissance, Wiedergeburt der Antike - sie geschah mehrfachI), im neunten, im zwölften und besonders erregend im 15. Jahrhundert; aber immer, wenn sie geschah, da­ mals und späterhin wieder im 17. und 19. Jahrhundert, mußten ihre Wiedererwecker die Antike auch aushalten können. Damit ist gemeint, daß z. B. Göttergestalten in der Antike bei aller Menschenähnlichkeit nicht nur immer eine gewaltige Macht behielten, denen die späteren Darstellungen zu entsprechen hatten, sondern daß in ihnen eine Spannung von Gegensätzlichem (Henrichs, Loss 235 ff.; Versne1133) herrschte, welche die Späte• ren nur allzu leicht durch Vereinseitigung oder dadurch ins Harmlose abgleiten ließen, daß sie z. B. die Göttinnen lieblich, die Götter verliebt darstellten und so mit der Wen­ dung ins Intime die uralte Spannung von Furchtbarkeit und Huld aus den Augen verlo­ ren.

  • The Metamorphoses of Magic: the Tempest and a Tempest Read from the Perspective of the Metamorphoses
    6 / JOURNAL OF COMPARATIVE LITERATURE AND AESTHETICS The Metamorphoses of Magic: The Tempest and A Tempest Read from the Perspective of the Metamorphoses Jeremy Patterson Abstract he supernatural almost always plays a role in human myth-making. As a specific instance of the supernatural, magic is a significant element in Ovid’s TMetamorphoses, Shakespeare’s The Tempest, and Aimé Césaire’s A Tempest. These three works demonstrate the updating of magic in relation to sociopolitical concerns through the intertextuality of one speech. This article examines Medea’s speech on magic in the Metamorphoses, Shakespeare’s adaptation of it, and Césaire’s radical rejection and overhaul of it. For these writers, magic is a myth, or at least pales in significance when compared to human action and agency. None of the authors rejects the supernatural itself, but all of them focus their attention on what humans bring to the table, with or without magic. Keywords: Agency, Caribbean, Magic, Myth, Ovid, Shakespeare. 1. Introduction One of humanity’s most resilient cross-cultural myths is that of magic. This is not to say that the supernatural in general (or even the more specific term of magic) is necessarily a myth, but rather that the very possibility of the supernatural is integral to so much of human myth-making. The element of magic is often central to that process, and this article studies the significance of magic in three literary texts (Ovid’s Metamorphoses, Shakespeare’s The Tempest, and Aimé Césaire’s Une Tempête/A Tempest) with historical and cultural disparities, but which together demonstrate the development of the use of magic as a literary device.

    ECLAT D600.1 ECLAT D600.1 Report and “Lessons Learned” from the 1st ECLAT Scientific Workshop October 22 – 24, FMI, Helsinki, Finland Hermann Opgenoorth, IRF The workshop was the first in a sequence of four topically organised ECLAT workshops and it was dedicated to initiate the scientific quality control of the delivered ECLAT data products, in particular the reliability of Cluster footprint mapping using various models during various level of magnetospheric activities, including substorms and localised field aligned currents. The workshop was attended by 30 persons, stemming mainly from the teams of the participating ECLAT partners, CAA and ESA staff, and members of the ECLAT Advisory Board. The program/agenda of the workshop can be found in a separate appendix. All presentations during the workshop have been placed in a dedicated workshop folder on the Internet. In the following we will summarise the discussions under the various agenda items and point out “Lessons Learned” and decisions for “Action Items” for the next ECLAT workshop. Workshop Introductory Talks Steve Milan opened the workshop with a general introduction to the ECLAT project. Rumi Nakamura and Pete Boakes gave a status update on the OEAW region identification product and event finding activities. • The defined and characterised regions are: Lobe, boundary region, outer plasma sheet, inner plasma sheet, the neutral sheet and the plasma sheet boundary layer. • In addition to the identification of such boundaries there will be event lists addressing in particular dynamic features like wavy current sheet, depolarization events and occurrences of thin current sheets and large FACs. • In the following discussion the issue of a difference between OPS (being a region dominated by currents) and PSBL (being dominated by flows) was raised and discussed.

Invent a Planet: Students may create (draw, paint, montage, build from household or classroom items, what- ever!) a planet. Does it have air? What color is its sky? Does it have ground? What is its ground made of? What is it like on this world? Invent an Alien: Students may create (draw, paint, montage, build from household items, etc.) an alien. To be fair to the alien, they should be sure to provide a way for the alien to get food (what is that food?), a way to breathe (if it needs to), ways to sense the environment, and perhaps a way to move around its planet.
