Millet microremains—an alternative approach to understand cultivation and use of critical crops in Prehistory

The term “millets” is used to identify several genera of grasses (Poaceae), most of which belong to the subfamily Panicoideae. Millets are one of the major food sources in arid and semi-arid areas of the world and they have been important crops in the prehistory of Africa and Eurasia. In this paper, we discuss phytoliths and starch grains from two of the less studied major millets (Pennisetum glaucum and Sorghum bicolor) as well as from some small millet species that are not normally considered of much importance (so-called forgotten millets: Digitaria ciliaris, Echinochloa colona, Echinochloa frumentacea, Brachiaria ramosa, Setaria pumila and Setaria verticillata). The preliminary results of this study on phytolith morphology, both at single and joined (silica skeletons) morphotypes, and starch grains show great potentials for the identification of different genus or species on the basis of microremains.     

Cultural quarters and urban regeneration – the case of Cathedral Quarter Belfast

Elements of culture and cultural policy have now become firmly integrated within urban design and regeneration practice. Culture is recognised as a driver of economic renewal and many cities have utilised culture as an additional means of achieving regeneration outcomes through the application of designated cultural quarters. This study provides a critical evaluation of the regeneration and development of Cathedral Quarter Belfast, exploring the integration of cultural and economic strategies to encourage greater cultural provision and economic development as well as examining the role of culture as a catalyst in the regeneration process. It does so by utilising a mixed methodology incorporating qualitative key informant interviews and a quantitative survey of visitors to the quarter. This research examines and challenges existing theories in relation to culture-led regeneration making a valuable contribution to the literature on the application of cultural quarters and identifies areas for further investigation.     

Of Gates in the Ground and Castles in the Air: A Case of Biblical Unreal Estate

ABSTRACT

The latter part of Psalm 24 describes the personified gates of Jerusalem as raising themselves up in order to allow the King of Glory to en-ter. This, in addition to the rest of the strong mythical overtones of the psalm, creates an image of architecture coming alive to join in the celebratory entry of the divine ruler.

There are numerous, but no definitive, suggestions as to the identity of who or what is supposed to be entering the gates and under what circum-stances as well as how the raising gates are to be understood. In this essay it is argued that the psalm only supplies half the data and that it forms the optimis-tic complementary ending to the anguished cry of despair of Lam 2,8–9. Ap-plying critical spatial analysis to these two texts, in addition to other support-ing material, will not only show that one is a response to the other, but may also provide a more secure dating for the psalm and its social setting as well as a clearer understanding of the specific metaphor of personified architec-ture.     

Studying the Cannons of Punta Santa Anna,Spain: In Situ Conservation,Promoting Public Access,and Monitoring Iron Corrosion

The 2001 UNESCO convention for the Protection of Underwater Cultural Heritage (UCH) encourages and supports projects that would make accessible to the general public underwater cultural sites. Since 2010 the Catalonian Federation of the World Underwater Federation (FECDAS), have been developing outreach activities with the objective of promoting the protection of the UCH among recreational scuba divers. The purpose of this paper is to introduce one such project, the Punta Santa Anna in Blanes, Spain. This project has three objectives: the promotion of UCH to the general public, the in situ protection of this underwater archaeological site, and a case study on iron corrosion processes. FECDAS/CMAS will create an underwater archaeological park where recreational scuba divers will be able to visit some purposely selected archaeological iron cannons. To expose UCH to the general public will potentially affect the integrity of these artefacts. This risks potential damage and so, with the objective of minimizing potential threats, a series of protective measures and a systematic monitoring programme have been planned. The programme is designed to study the relationship between the underwater environment and the artefacts. The aim is to acquire a better understanding of the corrosion processes of iron objects present in marine underwater sites.     

Archaeometric investigation of Roman tesserae from Herculaneum (Italy) by the combined use of complementary micro-destructive analytical techniques

Vitreous tesserae from two mosaics in Herculaneum (Italy) dating from the 1st century AD have been investigated in order to gather information on Imperial Age opaque glass. The combined use of complementary micro-destructive analytical techniques, namely optical microscopy (OM), scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS), inductively coupled plasma-mass spectrometry (ICP-MS), transmission electron microscopy (TEM), and X-ray powder diffraction (XRPD) allowed to define the nature of formers, fluxes, chromophores and opacifying compounds and to determine the type of raw materials employed for their introduction. The results confirmed the high technological level of Imperial Age glassmakers and clarified some details of the production processes. Experimental data have been obtained concerning formation of antimony-based opacifiers. The presence of tin-containing Ca- and Pb-antimonates has been ascertained in various green, yellow and turquoise tesserae. Moreover, unusual divergences from the established Roman age ‘low magnesia–low potash’ (LMLK) glass composition have been found for some red and green samples.
