The Society of Antiquaries and the Invention of the History of Parliament
Authors: Gajda Alexandra
Published: September 2024

ABSTRACT: Soon after the accession of James I to the English throne, the Society of Antiquaries debated the origins of the English Parliament. Records of their debates, notably the tract of Sir John Doddridge, were compiled and circulated widely in manuscript before their print publication during the Interregnum. The tracts asserted that parliaments had ancient origins predating the Norman Conquest and, in Doddridge’s case, even the origins of monarchy in England. Scholars have argued that these tracts articulated an understanding of England’s immutable “ancient constitution,” in which a stance on Parliament’s antiquity defined a position on the scope and limitations of royal power. This article explores the tracts in light of the context in which they were written—the putative Jacobean Union, and the new king’s assumption of the royal supremacy over the Church of England. It argues that the assertion of the antiquity of Parliament was not incompatible with an understanding of the complex development of the assembly’s history over time, especially its mutability at the hands of the Crown. As such, these early attempts to understand the institution’s history, and its transformations under different monarchs, may have fueled the existential fears for Parliament’s future that characterized the turbulent parliaments of the 1620s.
Mercurius Aulicus , The Court Mercury: Royalist Journalism and Political Factionalism, 1643–1645
Authors: Macadam Joyce
Published: September 2024

ABSTRACT: Due to the paucity of Royalist material that survived the first English Civil War, the Oxford newsbook Mercurius Aulicus , which ran almost continuously from January 1643 to September 1645, is an invaluable source for historians of the period. However, few scholars have examined the entire run of the journal in detail. This article’s major theme is the extent to which evidence of factionalism among the king’s most important advisers, civilian and military, can be deduced from the newsbook. It begins with an examination of the practical aspects of Aulicus ’s publication, its editorial staff, its intended readership, the nature of its content and sources of intelligence, and the overall strategy and tactics it employed to convey its message, all of which is essential for an understanding of Aulicus ’s position with regard to Royalist factionalism. The article then analyzes the journal’s text for evidence of the divisions that plagued Royalist counsels during the first civil war. It concludes with an assessment of Aulicus ’s representations of Charles I, and the difficulties faced by the newsbook in this regard.
The Noahide Commandments in the Jerusalem Talmud from a Cairo Geniza Fragment
Authors: Cherlow Elyashiv
Published: September 2024

Abstract: Numerous quotations by medieval scholars from tractate ‘Avodah Zarah of the Jerusalem Talmud are not to be found in extant texts. This has led some scholars to suggest that a long passage, probably dealing with the Noahide commandments, is missing from our extant editions. Other scholars have argued that this was not an original passage in the Jerusalem Talmud but rather a later addition known to these medieval scholars. This article presents for the first time a direct textual witness of this passage from the Cairo Geniza. This new finding raises the need to reexamine the question of the provenance of this passage.
Yehuda Amichai’s “Hayi Shalom” and Other Partings
Authors: Gold Nili
Published: September 2024

Abstract: This essay broadens Yehuda Amichai’s corpus in order to understand the multiple sources—textual, intertextual, and autobiographical—that came together into the poem “Hayi shalom” (“Farewell”). This analysis of the poem incorporates, for the first time, the hundred love letters Amichai wrote to his girlfriend Ruth Hermann in 1947–48; interviews and conversations with Dr. Clarice Kestenbaum, the woman who is the subject of the poem; and remnants of Clarice’s correspondence with Amichai in 1958–61. Through an idiosyncratic kind of interpretation, an essentially personal one, using sources often overlooked in scholarship, the analysis deciphers the secret language of the poem, tracing linguistic footprints from letters as well as the poet’s notes and drafts. Through the story of Amichai’s 1958 separation from Clarice Kestenbaum, the article reveals how their Jerusalem love affair is encoded in the language of “Hayi shalom.” Moreover, it demonstrates how, through the linguistic and experiential texture of the poem, the separation from Clarice joins with other partings in Amichai’s life—especially the unknown story of his heartbreak over Ruth Hermann. Finally, the grief for Amichai’s childhood friend “Little” Ruth Hanover, who perished in the Holocaust, forms the base of the fundamental, formative loss in the poem—and, in fact, in Amichai’s oeuvre. While “Hayi shalom” is dedicated to the day of separation from Clarice, in its hidden corners lie the partings and abandonments that preceded it. In its indirect way, the poem confronts two deaths.
Shema as Memory Palace: A Medieval Hebrew Ars Memorativa
Authors: Katz Rachel B.
Published: September 2024

Abstract: Leon Modena’s Lev ha-Aryeh (seventeenth-century Italy) has long been recognized as the first Hebrew treatise on mnemonics. This article points to an earlier source: gate 90 of Isaac Arama’s ‘Akedat Yits@hak . Arama not only describes the locative memory palace developed by Roman orators and popular throughout Latin Christendom. He contends that the original memory palace was given by God to the Israelites and consists in none other than the central prayers of Jewish liturgy, the Shema and ve-ahavta . On Arama’s reading, the Shema and ve-ahavta are designed as a sort of verbal memory palace to help store and recollect all the commandments. In addition to introducing Arama’s memory device and adaptation of classical ars memorativa into Hebrew, I show how Arama’s interest in memory reflects a departure from earlier trends in medieval Hebrew philosophical literature. Surveying Hebrew philosophical literature across Spain and southern France from the thirteenth through mid-fifteenth centuries, I argue that although Jewish authors conceptualized memory as a faculty and internal sense according to the framework of Aristotelian psychology, they did not seem to be especially interested in the subject of memory as compared with their Christian peers. I conclude by hypothesizing what may have precipitated renewed Jewish interest in memory in late fifteenth-century Spain.
Jewish History Must Be Defended
Authors: Stern Adam Y.
Published: September 2024

Abstract: This essay stages an encounter between Michel Foucault and Franz Rosenzweig by juxtaposing their parallel observations on the continuity between history and war. While Foucault analyzes the strategies organizing seventeenth-century historical writing about the Norman conquest of England and the Frankish invasion of Gaul, Rosenzweig opposes the warlike progress of Christian history to the eternal peace of Jewish time. Through this comparison, the essay reevaluates the terms governing well-known debates about Jewish history and Jewish memory. It asks what role the concept of “war” has played in the emergence of modern Jewish historicism and the so-called Jewish return to history. The essay concludes by submitting the Israelite conquest of Canaan as a supplement to Foucault’s examples and as a critical index of the bellicose grammar underwriting the representation of Jewish history as a field of struggle.
Another Place, Another Prison: Marie Mancini Colonna's Negotiation of Autonomy
Authors: Nelson Sarah
Published: September 2024

Abstract: Marie Mancini (1639-1715) is best known today as Louis XIV's first love, but when it was determined that he was to marry the Spanish infanta, she was obliged to leave the French court and accept marriage to Rome's leading nobleman, Lorenzo Onofrio Colonna. The couple reigned supreme over the musical and theatrical culture of Rome for a decade before their relations soured and Marie began to fear that her husband might lock her away or perhaps even kill her. She and her sister Hortense, who had come to Rome after fleeing her own marriage in Paris, took the risky and scandalous step of running away together and beginning lives on the road, seeking a way of living independently under the protection of sovereigns throughout much of Western Europe. It could be said that Marie Mancini's life was one long struggle for autonomy and freedom. She took bold, unconventional, even scandalous steps to win her freedom, and over and over, she resorted to "deploying" her own confinement in pursuit of greater liberty. This article focuses on three types of confinement which threatened Marie—physical imprisonment, social/political constraint, and narrative circumscription—and analyzes the strategies she employed to counter them.
Cronos and the Queer Belly: A Politics of Confinement in the Work of Linda Lê
Authors: Sherman Elara
Published: September 2024

Abstract: The word "sickness" falls short in encompassing the plethora of rashes, expectorations, phobias, fantasies, tumors, nostalgias, quarantines, suicides… which clutter the pages of Linda Lê's novel, Cronos . Held hostage by her love for her ailing father, Una describes her father's dementia as a regression into childhood. Meanwhile, the tyrannical Karaci writhes behind closed doors in a state of "lycanthropie"—he is a "squelette ambulant," who, in moments of extreme illness, resembles a fetus (Lê 13; 16). This essay employs the resources of disability and postcolonial studies to analyze the often-disturbing depictions of human bodies in Cronos , in terms both of a general language of "health" and "sickness" as well as particular visions of children and pregnancy. Furthermore, I connect this analysis of human bodies to the political body—one which is repeatedly described as rife with "cancer" (136). In her depictions of "sickness" and "health," Lê draws upon a rich history in political philosophy of comparing the health of the city-state to that of the (male) human being, and, further, makes an important intervention into this tradition by foregrounding gender through themes of caretaking and pregnancy. In a novel rife with illnesses, real and imagined, Lê's writing of gendered modes of resistance upsets a discourse of disability and violence surrounding "young," "underdeveloped" nations. Furthermore, I argue that this gendered resistance, rather than centering feminine (anti)maternity, finds its power in the figure of the queer belly. Neither stably gendered, nor precisely human, neither curative nor diagnosable, the queer bellies of Cronos suggest what I would like to call "a politics of confinement" at the heart of Lê's feverish text.
Is the Rhetorical Ethos a Gendered Form of Confinement? The Case of Christine de Pizan
Authors: Montenegro Tina
Published: September 2024

Abstract: Influenced by the long-lasting metaphorical association of enclosure and confinement with the feminine, this article asks if Christine de Pizan was "confined" by the art of rhetoric—in particular, the rhetorical ethos —when she wrote, and if we are "confined" by our desire to find the truth about Christine's life in her writings. An analysis of Christine's prologues shows how she weaves together the topoï of feminine humility, domestic education, and widowhood with seemingly personalized circumstances to give readers a credible image of the woman author. The Aristotelian concept of ethos is precisely both textual and referential and, as such, does not distinguish between one and the other, its only criterium is credibility. In this sense, Christine was not more "confined" than her fellow male authors; the conventional way for her to build credibility was simply different, as she was a rare case. In contrast, we are "confined" by our modern desires when we read Christine, which does not mean that we do not benefit from trying to use historicized concepts in our analyses.
Constrained Intimacy: Sexual Productions in Sophie Calle's Les dormeurs
Authors: Carr Jennifer
Published: September 2024

Abstract: Over nine consecutive days in April 1979, Sophie Calle invited friends, family, and strangers to occupy her bed, which became a cloistered site of sleep, conversation, and erotic possibility. Confined to Calle's Paris apartment, participants were photographed and interviewed, the results exhibited and eventually published under the title Les dormeurs (2000). This article reads both the procedural constraints that govern Calle's original project (pre-determined parameters that structure her interactions with participants) and the (para)textual strategies Calle later used to shape Les dormeurs , the published text, as generative devices. Together, they activate narrative conventions that, in the project's intimate bedroom setting, correlate with narrativizations of conventional sexuality. Confronted by the latent eroticism and ambient queerness of Les dormeurs's unsettled bounds (between artist and subject, ordinary and strange), participants—confined to a domestic space suddenly rendered uncanny—are compelled to reconsider sex's familiar apparatus: the bed. Their consequent insistence on the comparably familiar apparatus of normative sexuality lends it a compulsory, performative aspect as, within Les dormeurs's artificiallydetermined bounds, participants' claims to heteronormative desires are all the more troubled for being asserted as self-evident.
DMD and microlens array as a switchable module for illumination angle scanning in optical diffraction tomography
Authors: Yang Siqi , Kim Jeongsoo , Swartz Mary E. , Eberhart Johann K. , Chowdhury Shwetadwip
Published: September 2024

Optical diffraction tomography (ODT) enables label-free and morphological 3D imaging of biological samples using refractive-index (RI) contrast. To accomplish this, ODT systems typically capture multiple angular-specific scattering measurements, which are used to computationally reconstruct a sample’s 3D RI. Standard ODT systems employ scanning mirrors to generate angular illuminations. However, scanning mirrors are limited to illuminating the sample from only one angle at a time. Furthermore, when operated at high speeds, these mirrors may exhibit mechanical instabilities that compromise image quality and measurement speed. Recently, newer ODT systems have been introduced that utilize digital-micromirror devices (DMD), spatial light modulators (SLMs), or LED arrays to achieve switchable angle-scanning with no physically-scanning components. However, these systems associate with power inefficiencies and/or spurious diffraction orders that can also limit imaging performance. In this work, we developed a novel non-interferometric ODT system that utilizes a fully switchable module for angle scanning composed of a DMD and microlens array (MLA). Compared to other switchable ODT systems, this module enables each illumination angle to be generated fully independently from every other illumination angle (i.e., no spurious diffraction orders) while also optimizing the power efficiency based on the required density of illumination angles. We validate the quantitative imaging capability of this system using calibration microspheres. We also demonstrate its capability for imaging multiple-scattering samples by imaging an early-stage zebrafish embryo.

Published: September 2024

It's fascinating to witness the significant progress achieved in leveraging colloidal nanocrystals as a viable platform for infrared optoelectronics. Their adaptability as a spin-coatable resist with infrared photoactive properties has spurred developments that transcend mere material advancements and delve deeply into advanced device design. A standout accomplishment in the infrared domain is the development of infrared cameras utilizing nanocrystal thin films as their active layers. This marks a paradigm shift in infrared imaging, challenging the long-held focus on high-quality monocrystalline thin films. The emergence of nanocrystal films, despite being highly polycrystalline, enables the fabrication of cost-effective sensors that are beginning to rival established technologies like InGaAs, especially in the short-wave infrared.Among potential materials, HgTe1 stands out as the most versatile platform, capable of spanning the entire infrared spectrum from visible wavelengths for the most confined forms to THz2 frequencies for bulk-like particles. In this presentation, I will begin by reviewing recent advancements in transitioning HgTe nanocrystal films from single-pixel sensors to high-quality imagers34.However, achieving such imagers marks just the beginning of the journey. One key challenge revolves around the interaction between light and matter. The polycrystalline nature, while enabling cost-effective sensors, does come with a trade-off – reduced mobility compared to bulk films, limiting the efficiency of charge collection. Therefore, introducing processes to focus light on a film thickness within which transport remains efficient becomes critical. In the latter part of the presentation, I will demonstrate how the incorporation of nanophotonic structures can introduce new functionalities such as actively reconfigurable spectral responses5 and the extension of the device's spectral response into the mid-infrared range.The broad spectral tunability of HgTe nanocrystals also positions them favorably for thermal imaging. However, in this spectral range, the entire device architecture needs a reevaluation compared to visible wavelengths. Notably, the transparent conductive oxide layers typically used as electrodes exhibit weak transmission characteristics, necessitating alternative designs for transparent and conductive electrodes. Here, I will illustrate how the utilization of exalted transmission effects can enhance the design of high-performance mid-infrared sensors.6Schematic illustrating transformation of nanocrystal solution into an infrared focal plane array and finally exemple of image obtained with the imager
