"Acheiro-poïétique" du cinéma: le Christ révélé par l'écran

Selon la tradition orientale, les représentations de Jésus trouveraient toutes leur origine dans les images acheiropoïètes, c'est-à-dire dans des figurations de la "Sainte Face" du Christ non faites de main d'homme, mais survenues par apparition divine -sur le voile de Véronique, le Saint Suaire, le mandylion d'Edesse, etc. Ces images qui, pour des théologiens de l'icône tels que Léonide Ouspensky, ne sont rien moins que "la manifestation du miracle fondamental : la venue du Créateur dans sa création" (in L'Image du Christ non faite de main d'homme, 1989), ont toujours été le ferment d'expérimentations multiples chez les peintres et les sculpteurs.Mais la réflexion artistique s'est cristallisée au moment où ces images sont devenues l'apanage de médiums issus de "l'ère de la reproductibilité technique" chère à Benjamin. En effet, les images "théographes" auraient pour spécificité d'être engendrées et de se multiplier par empreinte immédiate: une toile quelconque n'aurait qu'à être touchée par le visage du Christ pour devenir instantanément le support du divin portrait, et acquérir dès lors le "pouvoir reconnu aux acheiropoïètes de créer des doubles de même valeur, par simple contact" (François Boespflug, Dieu et ses images. Une histoire de l'Eternel dans l'art, 2008). Comment mieux faire écho aux principes mêmes de l'image (ciné)photographique, générée par indicialité et reproductibilité? André Bazin a eu l'intuition de cette parenté dans le cadre de sa théorisation sur le pouvoir "révélateur" de l'image (ciné)photographique qui selon lui procéderait "par sa genèse" de "l'ontologie du modèle" et "serait" le modèle; il a évoqué le Saint Suaire de Turin comme rejouant, voire emblématisant cette même "ontologie de l'image photographique" (dans l'article homonyme de 1945). Si Bazin ne développe pas plus avant ses considérations, la corrélation des dispositifs (ciné)photographique et acheiropoïète a connu un questionnement « en actes », au sein des films cherchant à représenter Jésus.Valentine Robert s'intéresse à ces expérimentations, à commencer par un projet de film d'Abel Gance de 1947, resté inachevé, où le suaire de Turin devait se transformer en écran de cinéma. Plusieurs autres productions seront abordées, telles que Civilization ou The Robe, qui explorent les effets visuels permis par la pellicule pour montrer le Christ en surimpression, dans une sorte d'"apparition technologique", ou telles que The Jesus Film ou The Passion of the Christ, dont la projection a été reçue par certains publics comme une apparition sacrée réactualisant l'Incarnation. Les modalités de la représentation des images acheiropoïètes et plus généralement de l'apparition de Jésus à l'écran seront enfin évoquées - de la tradition hollywoodiennes qui consistait à refuser l'accès de la "Sainte Face" à la pellicule et de la rejeter hors-champ jusqu'aux séquences d'Ecce Homo de Scorsese et Zeffirelli, en passant par la révélation visuelle inaugurant The King of Kings, qui pousse à son paroxysme la collusion entre apparition divine et apparition cinématographique.

Molluscicidal action of the latex of Euphorbia splendens var. hislopii N.E.B. ("Christ's Crown") (Euphorbiaceae) against Lymnaea columella (Say, 1817) (Pulmonata: Lymnaeidae), intermediate host of Fasciola hepatica Linnaeus, 1758 (Trematode: Fasciolidae): 1- test in laboratory

The latex action of Euphorbia splendens var. hislopii (Christ's Crown) against snails Lymnaea columella, intermediate host of Fasciola hepatica, derived from irrigation ditches of the Station of Pisciculture at Universidade Federal Rural do Rio de Janeiro, was studied in the laboratory. Lab bioassays, using aqueous solutions of the latex, varying between 0.1 and 10 mg/l, have proven molluscicidal activity of the product collected on the same day the tests were performed, during the four seasons of the year, finding the following lethal concentrations (LC90): 1.51 mg/l in the spring; 0.55 mg/l in the summer; 0.74 mg/l in the fall and 0.93 mg/l in winter, after 24 h exposure of the snails, showing significant differences among the seasons of the year (ANOVA test, F = 11.01, G.L.= 3/33, p < 0.05), as well as among the concentrations (ANOVA test, F = 27.38, G.L.= 11/33, p < 0.05). In the summer, mortality reached 100% from concentration at 0.6 mg/l, the same during fall and in winter as of 1 mg/l, while in spring it only reached 100% mortality as of 2 mg/l. Mortality in the controls was low, reaching 5% in the summer and winter and 10% in the fall and spring. None of the samples died. During the assay, with an aqueous solution of the latex at a concentration of 5 mg/l, in order to check the time of duration of the product effect, in the laboratory, it was observed that the molluscicidal activity remained stable up to the 15th day after the beginning of the test with 100% mortality of L. columella, gradually losing its effect until the 23rd day, when we no longer observed animal mortality. In the control group, there was a random daily variation in mortality rate ranging 0-50% after 48 h of observation for 30 days.

The girl from the Church of the Sacrament: a case of congenital syphilis in XVIII century Lisbon

Syphilis is a sexually or congenitally transmitted infectious disease with an impact on the health of human populations that has undergone important cycles in different countries and periods of history. Its presence was first diagnosed in Europe in the late XIV century. In Portugal, although there are various written records of the infection in the last centuries, there are rare references to it in archeological findings (mummified bodies are also rare in Portugal). The current study describes a probable case of congenital syphilis in an 18-month-old girl buried in the Church of the Sacrament in Lisbon. Her body, dating to the XVIII century, was found mummified together with dozens of others, still not studied. Symmetrical periostitis of the long bones, osteitis, metaphyseal lesions, left knee articular, and epiphyseal destruction, and a rarefied lesion with a radiological appearance compatible with Wimberger's sign all point to a diagnosis of congenital syphilis. The diagnosis of this severe form of the infection, possibly related to the cause of death in this upper-class girl, calls attention to the disease's presence in XVIII century Lisbon and is consistent with the intense mobilization at the time in relation to the risks posed by so-called heredosyphilis. It is the first case of congenital syphilis in a child reported in archeological findings in Portugal, and can be correlated with other cases in skeletons of adults buried in cemeteries in Lisbon (in the XVI to XVIII centuries) and Coimbra (XIX century). Finally, this finding highlights the need to study the entire series of mummified bodies in the Church of the Sacrament in order to compare the paleopathological findings and existing historical documents on syphilis, so as to expand the paleoepidemiological knowledge of this infection in XVIII century Lisbon.

Paleoparasitologic, paleogenetic and paleobotanic analysis of XVIII century coprolites from the church La Concepción in Santa Cruz de Tenerife, Canary Islands, Spain

We present the results of a paleoparasitologic, paleogenetic and paleobotanic analysis of coprolites recovered during the excavation of the church La Concepción in Santa Cruz de Tenerife. Coprolites (n = 4) were rehydrated and a multidisciplinary analysis was conducted. The paleobotanic analysis showed numerous silicates, seeds and fruits of the family Moraceae. In the paleoparasitologic study, Ascaris sp. eggs (n = 344) were identified. The paleogenetic results confirmed the Ascaris sp. infection as well as the European origin of human remains. These findings contribute to our knowledge of ancient helminthes infections and are the first paleoparasitological record of Ascaris sp. infection in Spain.

Impact of thermal proofing of a church on its indoor air-quality - The combustion of candles and incense as a source of pollution

Some years ago, a parish in Geneva decided to reduce heating costs by insulating its church to make it more energy efficient. Three years after the last renovations, it was observed that the internal surfaces of the naves had already become dusty compared with the customary frequency of 10-12 years. Dust even deposited on various surfaces during religious services. Our investigation showed that nearly all the dust found inside the church may in fact be soot from incense and candle combustion. Incense appears to be a significant source of polycyclic aromatic hydrocarbons. With a mechanical ventilation system and petrol lamps resembling candles the problem can be resolved.

A genealogical conceptual model using ontologies

Roughly fifteen years ago, the Church of Jesus Christ of Latter-day Saints published a new proposed standard file format. They call it GEDCOM. It was designed to allow different genealogy programs to exchange data.Five years later, in may 2000, appeared the GENTECH Data Modeling Project, with the support of the Federation of Genealogical Societies (FGS) and other American genealogical societies. They attempted to define a genealogical logic data model to facilitate data exchange between different genealogical programs. Although genealogists deal with an enormous variety of data sources, one of the central concepts of this data model was that all genealogical data could be broken down into a series of short, formal genealogical statements. It was something more versatile than only export/import data records on a predefined fields. This project was finally absorbed in 2004 by the National Genealogical Society (NGS).Despite being a genealogical reference in many applications, these models have serious drawbacks to adapt to different cultural and social environments. At the present time we have no formal proposal for a recognized standard to represent the family domain.Here we propose an alternative conceptual model, largely inherited from aforementioned models. The design is intended to overcome their limitations. However, its major innovation lies in applying the ontological paradigm when modeling statements and entities.
