Thinking through “Vernacular Cosmopolitanisms”: Historical Archaeology in Senegal and the Material Contours of the African Atlantic

This article draws on recent archaeological research on coastal Senegal to examine how the concept of “vernacular cosmopolitanism” can contribute to scholarship about the construction of cultural hybridity in West Africa during the Atlantic era. It argues that Senegambia between the seventeenth and nineteenth centuries was a vibrant theater of international exchanges, and that archaeological examinations of these processes can both assist our understanding of regional history and enrich discussions about the African diaspora, diasporic identities, French imperialism, and Atlantic modernity. The study of material experiences can also raise critical questions about our conceptual categories and limits to our understanding of the Atlantic past.     

The Invention of History: The Pre‐History of a Concept from Homer to Herodotus

The following pages, which deal with the pre‐history of the concept of history from Homer to Herodotus, first propose to decenter and historicize the Greek experience. After briefly presenting earlier and different experiences, they focus on three figures: the soothsayer, the bard, and the historian. Starting from a series of Mesopotamian oracles (known as “historical oracles” because they make use in the apodosis of the perfect and not the future tense), they question the relations between divination and history, conceived as two, certainly different, sciences of the past, but which share the same intellectual space in the hands of the same specialists. The Greek choices were different. Their historiography presupposes the epic, which played the role of a generative matrix. Herodotus wished to rival Homer; what he ultimately became was Herodotus. Writing dominates; prose replaces verse; the Muse, who sees and knows everything, is no longer around. So I would suggest understanding the emblematic word “historia” as a subsititute, which operates as an analogue of the (previous) omnivision of the Muse. But before that, Herodotean “invention”— the meeting of Odysseus and the bard Demodocus, where for the first time the fall of Troy is told—can be seen as the beginning, poetically speaking at least, of the category of history.     

Experimental characterization of the constitutive materials composing an old masonry vaulted tunnel of the Paris subway system

A significant proportion of the Paris metro tunnels comprise a masonry vault built out of stone blocks and mortar joints, and sidewalls and slabs made of unreinforced concrete. In order to provide the necessary data for future structural evaluation, an extensive laboratory testing programme has been conducted to characterize the materials of the tunnel separately, i.e., mortar, stone, and concrete. The tests, carried out on specimens taken from cores extracted from a 1930s tunnel, enabled to determine the mechanical properties, including direct tensile, shear strength, and mode I fracture energy, as well as the properties of the stone-mortar interface. Results show that the masonry mortar joints could reach 10 cm in width, and that blocks of stone varied in composition and porosity, thus producing a wide range of mechanical properties. The concrete was composed of large-sized aggregates and showed low stiffness and strength. Based on these experimental results, ratios between mechanical characteristics are hereby proposed. Perspectives on the use of this experimental data in a finite element model are then discussed.     

History and Characteristics of Construction Techniques Used in Traditional Timber Ottoman Houses

The aim of this article is to make a comprehensive review of the traditional timber house constructions in Turkey, which constitutes the majority of the existing Ottoman architectural legacy. After a short historical background focused on the Ottoman territory, the first section explores regional differences in the housing tradition, developed according to local features and defined by architectural features, material characteristics, and availability of materials. Derived from these regional differences, in the second section diversity in traditional timber construction systems in Turkey is described with special emphasis on the Ottoman h?m?? system. In this part, besides the discussion of the h?m?? technique which spread over Ottoman lands from the Balkans to Syria, the timber masonry and frame systems of the Eastern Black Sea Region and Thrace are presented in detail with visual support.
