Book art as historical evidence: disputation and representation in late medieval Germany

ABSTRACT

The increase in the distribution and availability of images for personal use in the late Middle Ages raises the question of their potential historical value for understanding the societies that produced and made use of them. This paper exposes the effects and the historical meanings of some woodcut illustrations of disputations between Jews and Christians: the woodcuts were widespread during the 1470s and 1480s in Swabia and Bavaria and surrounding areas, and they are still familiar and continue to play a role in shaping perceptions of Jewish-Christian relations of that period. These images do not reflect actual events: rather they are misrepresentations of polemical anti-Jewish sermons, designed as fictitious scholarly discourses. Their historical value is not limited to their ability to expose hidden angles. They can guide us to a better understanding of the written sources and to find new meanings there.     

A Late Hellenistic–Early Roman Fortress at Khirbat Mudayna as-Saliya,Central Jordan

ABSTRACT

Mudayna as-Saliya is a fortress site at the summit of an isolated promontory near the eastern end of Wadi Mujib, central Jordan. Archaeological surveys of the site have exposed potential evidence of Iron Age and classical period use with its occupational zenith in the late Hellenistic-early Roman period. The ruin on the surface is remarkably similar in architectural and hydrological design to the fortress of Machaerus. This paper, based on available survey data, suggests that the Hasmoneans were responsible for the construction of the fortress at Mudayna as-Saliya, which was reused by the Nabateans during the early Roman period. Finding a potential Hasmonean desert fortress on the desert fringe of eastern Transjordan was unexpected, and it might have significant ramifications for the study of Hasmonean, Herodian, and Nabatean kingdoms in central Jordan.     

Hydraulic engineering and irrigation agriculture in the Moche Valley,Peru: c. A.D. 1250–1532

This paper examines the hydraulic properties (i.e. velocity and discharge) of the main late prehistoric canals of the Moche Valley. Velocities, estimated from excavated canal sections using the Manning flow equation, are compared to tables of maximum permissible velocities and reveal that canals were constructed to transport water efficiently, but that on gradients steeper than 1:100 the Chimu and Inca engineers were unable to transport large discharges without severe erosional problems. Discharge estimates are compared with modern field requirements, using a known ethnographic watering cycle. This demonstrates that in almost every instance the channel size was of the same order of magnitude as that predicted from the requirements. The construction of the Inter-valley canal to bring water to the state lands in Moche was a technological disaster.
