We synthesize environmental and cultural change following a volcanic eruption at A.D. 846–848 in Subarctic North America to demonstrate how social relationships shaped responses to natural disasters. Ethnohistoric accounts and archaeometric studies reveal differences in human adaptations in the Yukon and Mackenzie river basins that relate to exertions of power over contested resources versus affordances of security to intercept dispersed migrating animals. The ways that pre-contact hunter-gatherers maintained or redressed ecological imbalances influenced respective trajectories of resilience to a major event. Adaptive responses to a volcanic eruption affected the movement of bow and arrow technology and the proliferation of copper use in northwest North America.

Abstract The accurate prediction of warm-season convective systems and the heavy rainfall and severe weather associated with them remains a challenge for numerical weather prediction models. This study looks at a circumstance in which quasi-stationary convection forms perpendicular to, and above the cold-pool behind strong bow echoes. The authors refer to this phenomenon as a “bow and arrow” because on radar imagery the two convective lines resemble an archer’s bow and arrow. The “arrow” can produce heavy rainfall and severe weather, extending over hundreds of kilometers. These events are challenging to forecast because they require an accurate forecast of earlier convection and the effects of that convection on the environment. In this study, basic characteristics of 14 events are documented, and observations of 4 events are presented to identify common environmental conditions prior to the development of the back-building convection. Simulations of three cases using the Weather Research and Forecasting Model (WRF) are analyzed in an attempt to understand the mechanisms responsible for initiating and maintaining the convective line. In each case, strong southwesterly flow (inducing warm air advection and gradual isentropic lifting), in addition to directional and speed convergence into the convective arrow appear to contribute to initiation of convection. The linear orientation of the arrow may be associated with a combination of increased wind speeds and horizontal shear in the arrow region. When these ingredients are combined with thermodynamic instability, there appears to be a greater possibility of formation and maintenance of a convective arrow behind a bow echo.

The origin and dating of the bow and arrow in the Great Basin has been a key issue in a recent debate concerning a cultural hiatus between Archaic and Fremont. New stratigraphic and chronometric data from Dry Creek Rockshelter are presented to support previous evidence for an Archaic rather than a Fremont origin for this new weapon.

The focus of this paper is on the traditional Saami hunting in relation to the animal and hunting motifs on their drum, more specifially the southern Saami drums. One may wonder if it is possible for anyone to interpret a picture unconditionally. One has a certain ground of one's own to stand on and the question arises of whether this is the correct position, when -as in the present case — we approach another culture. We naturally include the experiences of our own culture in interpretations of another culture. The animal which is the commonest species on the southern Saami drums, is the reindeer. Other animals that occur are elks, wolves, beavers, foxes, snakes, among others. Considering the Saamis' hunting weapons, the most important of these were the bow and arrow, and the spear or spear shaft. Of these weapons it is the bow which is most often portrayed on drums. Also some trapping implement like a gin may appear on a drum, but in general we have little or no information about hunting or trapping methods at all.

This review focuses on the technical and social details of production, training, and use of archery equipment by a Native American tribe, the Apaches. The study aims to understand the use of the bow in the Mesolithic and Early and Middle Neolithic societies of the Old World. The paper further describes arrow ballistics. An arrow and bow with similar dimensions and materials to those used by the Apaches was reconstructed and used in ballistic experiments. Shooting and the subsequent model calculation showed that the effective range of arrows made of reed and projected by a bow of medium strength (16–18kg) was not more than approx. 20m. Due to the initial flat part of the ballistic trajectory, such arrows were quite efficient in close-range contests. Within the model calculation, a regression procedure was introduced to determine the arrow air-drag parameters from an ensemble of shots.

AbstractThe timing of the arrival of the bow and arrow in the New World and reasons for its adoption have long been discussed by archaeologists. It typically has been assumed that the bow and arrow provided mechanical and physical advantages over the atlatl and dart, particularly in long-range killing power. This experimental study examines the effectiveness of traditional bows and arrows to deliver lethal wounds to prey species of different sizes. The results suggest that the bow and arrow was effective in hunting prey species such as antelope and deer but ineffective in bringing down larger animals unless changes in hunting strategies were adopted. In contrast, the atlatl and dart would have excelled in large game hunting. It is proposed that the adoption of the bow and arrow and the abandonment of the atlatl and dart were conditioned by their distinct performance advantages and changes in the game species targeted over time.

AbstractThis is a short report on a selection of the small finds from the excavations of a Roman house which lies to the west of the theatre at Lepcis Magna. The pottery and coins from the current levels of excavation have been dated to the late 5th and early 6th centuries AD; however, many of the objects seem to be residual. One of the most interesting finds was a solid bronze ring, decorated with two female figures. The object seems to have been functional, with the ring and the bars on which the woman are seated being attached to a soft material such as leather. These characteristics, which can be found on parallel examples, along with other bronze artefacts from the site suggest that the former was part of the decoration of a horse drawn carriage. Several pieces of jewellery were found including two gemstones which were once part of a finger ring, dating from the 2nd century AD. The first is a garnet and shows the goddess Artemis/Diane in her role of huntress, holding a bow and arrow. The second, which is a cornelian, is decorated with a portrait of a youth and may well be a local copy of a type circulating at the time. Many pieces of locally crafted bone and ivory were also found, including a bone plaque with a floral decoration which was originally intended as a decorative inlay for a small object such as a box. A similar piece from Egypt has been dated to around the 3rd or 4th centuries AD.
