Petra,taxes and trade reconsidered in the light of the Petra Church archive

Much has been written about the Petra Papyri since their discovery in 1993. However, little has been published on their connection with taxes, and our understanding of Petra and trade has changed considerably in the last couple of decades. The papyri provide plenty of information concerning the material culture of Byzantine Petra. The purpose of this paper is to review the economic and historical information in the papyri related to taxes on the land, and to understand the economic reality in Petra and its hinterland during the Byzantine period. The papyri indicate the existence of a stable society and continuity of human settlement in Petra and its neighbouring areas such as Udhruh and Al-Sadaqa, especially after the frequent earthquakes that threatened the region between the fourth- and seventh-centuries AD. It is clear from the papyri that there is an advanced tax system in the Petra region during the sixth-century AD.     

Feeding the scavengers. Actualistic taphonomy in the Jordan Valley,Israel

This paper describes the results of a 3‐year project carried out in the Jordan Valley, Israel, in which the influence of specific local environmental conditions, such as scavenging, weathering and scattering of carcasses, were related to the rate of their bone survival. During the 3 year period, the taphonomy of 16 whole animal carcasses, deposited in a nature reserve and agricultural cultivated area were compared. The exact age, date of death and weight of all animals was known. Results of animal scavenging activities on the carcasses, such as disappearance of bones and damage, such as tooth marks, breakage, gnawing to the leftover bones, were recorded at the end of the initial, intensive scavenging period (Phase I), and at later dates. Bone scattering maps were drawn at the end of Phase I and 2.5 and 3 years later. Weathering of surviving bones at the sites is described. Results show that in the Jordan Valley Nature Reserve, scavenging is the most important taphonomic agent causing total disappearance of all bones of young dairy calves, and reducing amount of bones remaining of more mature animals to a minimum. These small number of leftover bones, after only 2–3 years are the only candidates for eventual burial and fossilization. The loss of most of the bones through scavenging in the nature reserve might cause serious bias to conclusions about subsistence behaviour of prehistoric man. This is a taphonomic actualistic analogue to eventual conditions in prehistoric times. Copyright © 2000 John Wiley & Sons, Ltd.     

The titles of Petra in the sixth century: the evidence from the Petra papyri

Since their discovery in 1993, the Petra papyri have drawn the attention of both historians and archaeologists because of the amount of information they contain. The content of the papyri essentially deals with the property inheritance and transaction of a certain Theodoros son of Obodianos and his family in Petra and its vicinity, in the period between AD 537 and 593. The present paper focuses on the titles of Petra mentioned in these papyri and on their importance for the understanding of Petra in the Roman and Byzantine periods. Petra's full titles are: ‘Imperial Colony Antoniana, Distinguished, Holy (?), Mother of the Colonies, Hadriana Petra, and Metropolis of [the Province] Tertia Palaestina Salutaris’. The main components of these titles are attested elsewhere, but they appear in their entirety in the Petra papyri for the first time. The various titles of Petra as they appear in the papyri concerned clearly indicate that Petra continued to style itself as an important place in the Byzantine Empire. The picture that emerges from Petra's titles and other evidence from the papyri is that, in the sixth century Petra was still a place inhabited by relatively wealthy people, which had a major role in the economy of the Byzantine Empire.     

Agriculture in sixth‐century Petra and its hinterland,the evidence from the Petra papyri

Since their discovery in 1993 the Petra papyri have drawn the attention of both historians and archaeologists because of the amount of information they contain. They deal with the property of Theodoros, son of Obodianus, and his family in Petra and its vicinity in the period between AD 537 and 593. This paper focuses on agriculture and its importance in Petra and the surrounding area in the sixth century AD, according to the information derived from the scrolls. It appears that agriculture played a major role in the economy of Petra and its hinterland at the time these documents were written. The papyri repeatedly mention agricultural lands throughout the region and in many cases specify their locations and toponyms. Some of the latter are significantly still in use. There is also information about springs, some of which are still active and contribute to local agriculture. Some papyri even contain information about the type of plants grown in the area. Finally, the authors present the current state of agriculture at selected places and compare it with the state of agriculture in the sixth century AD in the study area.     

3D Digital Documentation,Assessment, and Damage Quantifi cation of the Al-Deir Monument in the Ancient City of Petra,Jordan

Abstract

The rock-cut monuments in the ancient city of Petra in Jordan form an outstanding tangible heritage site. Unfortunately, this important part of the world's cultural heritage is gradually being diminished due to weathering and erosion problems. In this research, an approach combining in situ surveying and laboratory analysis is applied in order to provide sufficient and comprehensive data regarding the documentation and evaluation of the status of the Al-Deir monument in Petra. The purpose was not only to quantify the damage, but also to make a first step towards creating a 3D monitoring programme of the deterioration rate. The approach presents a correlation study between the environmental condition and the surface weathering damage, using 2D mapping of the weathering form and accurate 3D realistic modelling from laser scanning and digital photogrammetry. The 2D mapping provides detailed weathering damage information for the entire stone surface of the monument, whereas the 3D modelling provides information on the spatial distribution and texture of the damage. Additionally, the 3D digital model can provide reference data as an exact guide to the restoration needed. In order to support the visual presentation of 3D surface details, a hybrid approach combining data from laser scanning and digital imagery was developed.

Studies of stone texture and spatial distribution of soluble salts were carried out at the monument in order to explain the mechanism of the weathering problem. Relative humidity, temperature, and wind are the main factors in the salt damage process. In order to study the effect of these conditions in the salt crystallization process a series of fieldwork investigations and laboratory work were undertaken. The results show that visible zoning of weathering damage is correlated to different salt concentrations.

Life under lockdown: Notes on Covid-19 in Silicon Valley

This article is a preliminary exploration of the effects of Covid-19 in Silicon Valley, one of three pandemic ‘hotspots’ on America’s west coast. In particular, it describes how the crisis has deepened and magnified social and economic inequalities in a region where poverty, homelessness and gentrification are rife. Despite the fact that many technology firms are reaping massive profits in the wake of ‘shelter in place’ orders, many Silicon Valley workers have lost their jobs and are struggling to cope with the consequences of Covid-19. The article also analyzes the different meanings of ‘lockdown’ by comparing examples from China, Brazil, Taiwan and the United States. The authors conclude that anthropologists have a significant role to play in helping to understand how and why communicable diseases emerge, the underlying social and environmental conditions that fuel them and cross-cultural strategies for the effective mitigation of epidemics and pandemics.     

Multiple assessments of local properties,production, and performance in metal objects: an experimental case study from Petra,Jordan

This object-specific case study focuses on cupreous artifacts excavated from the Great Temple complex of Petra, Jordan to demonstrate how the use of compositional X-ray analyses alongside two experimental applications (ImageJ software and nanoindentation) have the potential to generate different and otherwise unobtainable information about archaeological metals. The study highlights the value of using multiple techniques as a means of resolving the ambiguities that tend to arise from interpretations of single-sited measurements on objects and from single-instrumental analyses during studies of production processes and consequent material performance. Employing different techniques on multiple localities within a sample permits the gathering of precise information about the behavior of and interrelationships between variables that affect the objects’ fabrication and use, particularly composition, structure, and hardness properties. The resulting data are interpreted in association with contextual archaeological information from Petra to consider the use-life and potential significance of these objects.     

Site conservation during excavation: treatment of masonry,wall plaster and floor mosaic remains of a Byzantine church in Petra,Jordan

Abstract

The conservation treatments carried out between June 1992 and August 1993 on the architectural remains of a Byzantine basilica in Petra, Jordan, during and immediately after the excavation are described. The treatments completed during excavation included: stabilization and consolidation of certain sections of the basilica's sandstone ashlar masonry; cleaning and consolidation of the unpainted lime wall plaster decorating the basilica interior; cleaning and consolidation in situ of the extensive remains of a figurative mosaic pavement in the two side aisles, and the fragmentary remains of the opus sectile pavement in the central aisle. The consolidation treatments included injection grouting using hydraulic mortar mixes produced in Italy, and mortar repairs using slaked lime and hydraulic lime. The existence of the mosaic required preventive conservation measures during the excavation, such as the construction of a temporary shelter over the site during the winter, the use of temporary protective facings over damaged areas of the mosaic, as well as the temporary backfilling of the mosaic with soil over a layer of geotextile in order to protect the mosaic between the initial phase of conservation work and the construction of a permanent shelter for the site in the near future. The importance of having a conservator present on site during the critical phase of excavation, when all materials are most susceptible to damage, is emphasized. The Petra Church Project will hopefully serve as a model for future excavations in that it employed two conservators from the beginning of the excavation: one for small finds, the other responsible for the site and the architectural remains removed from the site during the excavation.     

Towards a Risk Management and Conservation Plan for the Djin Blocks at the World Heritage Site of Petra,Jordan: The Case of Djin Block No. 9

Cultural heritage is subjected to many pressures and risks. Over the past few years, the use of digital technologies has significantly changed the approaches to cultural heritage documentation for the purpose of condition assessment and conservation. The integration of novel approaches and techniques has permitted a detailed examination and assessment of damage, deterioration due to weathering and erosion, and their mechanisms. This study seeks to contribute to the preservation and conservation of the significant heritage of the so-called Djin Blocks at the World Heritage Site of Petra in Jordan. While these three dimensional cuboid rock-cut monuments have been subject to extensive conservation studies, this is the first time they have been subjected to 3D recording and multispectral photography, with the aim of recording damage caused by the ravages of time.

This study presents the results of the documentation of the case study Djin Block No. 9. A variety of systematic documentation techniques were used, including 3D recording with terrestrial laser scanning (TLS), close-range photogrammetry, multispectral imaging, and thermography records. In addition, pathological studies of the erosion from various causes and an analysis of the effect of weathering on Djin Block No. 9 are performed. Based on this data, the paper presents recommendations for developing risk management and conservation planning of Djin Block No. 9.
