Update of my huge annotated atlatl/spearthrower bibliography
In this paper we describe a single sample of nineteenth and twentieth century bows and arrows of the Ovambo, Namibia. Unlike some other southern African bow-hunting groups, there is a paucity of literature describing the traditional hunting weapons of the Ovambo. Two types of bows and two broad types of arrows were observed, the latter each with multiple variants. The varied arrow designs reflect different types of prey and hunting techniques. There is apparently greater design affiliation with several Angolan tribes, such as the Ovimbundu, than with the Hei//om hunter-gatherers, with whom the Ovambo also interacted. We argue that the basic Ovambo weapon designs and hunting techniques were well established prior to their entrance into Namibia and was not affected tangibly by contact with the Hei//om. There are several features of the arrows that seem unique to the Ovambo material and are probably of local invention. We postulate probable functions of some of the arrow designs, although others remain ambiguous.

Drawing the Bow: A Re-examination of the Desert Hunt Scene in the Tomb of Khnumhotep II at Beni Hassan.2018 •
A recent publication of the Dynasty 12 tomb of Khnumhotep II (Tomb 3) at Beni Hassan has provided a unique opportunity to re-examine the rich and exceptionally detailed visual and textual repertoire in the tomb. Work undertaken by the Australian Centre for Egyptology has seen the tomb of Khnumhotep II re-recorded and published, highlighting that the earlier records of C.R. Lepsius and P. Newberry are frequently inaccurate and, furthermore, that some material was deliberately omitted. In particular, the line drawings of the walls published by Newberry are inadequate by modern standards as the figures and hieroglyphs as well as selected animal figures and inanimate objects are inexplicably rendered in solid black, obscuring many significant details. The present paper aims to examine the recently published record of the tomb (1) to conduct a visual analysis of the desert hunt scene on the north wall of the chapel of Khnumhotep II, with particular focus on identifying the method of drawing the bow used by the archers, and (2) to consider any discrepancies in the depiction of drawing the bow that are better understood via an appreciation of the established principles of ancient Egyptian two-dimensional representational art.
The study deals with the function of stone projectile points of the Late Pre-Pottery Neolithic B from Tell Halula in northern Syria. The focus of the study lies mainly on the morphological analysis of these tools with the aim of ascertaining the delivery mechanism they used, as such mechanism is only rarely found preserved. In order to achieve this objective, the study has employed recent morphometric methods along with available ethnographic data on projectile points that were retrieved from indigenous societies of North America and Australia as well as data obtained by means of experimental archaeology. Various significant ballistic attributes of the Byblos points of undetermined projectile type have been analysed and compared with samples of known use. The aim of this paper is to ascertain the type of weapons for which these tools were best suited based on morphometric attributes alone.
Projectile weapons affected the human evolutionary trajectory and propelled social and subsistence changes throughout our history. Archaeologists interested in such relationships must overcome two obstacles: How to recognize ancient weapons from fragmentary remains, and the difficulty of understanding their capabilities through experiments. The history of change in weapon systems shows a shift from relatively slow, heavy projectiles propelled by human strength to lighter, faster, mechanically propelled projectiles, which resulted in various effects on social institutions, subsistence, and evolutionary developments. Thrusting spears, hand-thrown javelins, and atlatls are all cited by various researchers as the weaponry used by Paleo hunters to bring down Pleistocene megafauna. A change from thrusting spears and javelins to effective atlatl-propelled projectiles would have made hunting large game substantially safer and increased the number of people in a group who could have participated. The subsequent replacement of atlatls by bows is another issue of wide debate. However, the dynamics of change in these complex systems are frequently debated and before we can compare prehistoric weapons in any meaningful way, we need accurate measurements of performance characteristics. Velocity is one important measure of projectile effect, directly influencing momentum and kinetic energy and thus the damage a projectile can do to its target, but accurate measurements of atlatl dart velocity are rarely reported. Atlatl dart velocity must be measured with naturalistic experiments involving human throwers, and while the problem of assessing discrepancies between the skill and strength of past and modern throwers cannot be fully circumvented, it is addressed here by measuring numerous well-practiced individuals using a variety of atlatl equipment, and comparing the results. We present several different series of experiments with radar gun, film, and chronograph to measure dart velocities. The atlatls used in hunting and warfare probably did not accelerate darts much beyond 35m/s (78 mph). This information is briefly applied to two issues: 1.We discuss Hutchings’ use of fracture velocity measurements on stone points to distinguish Paleoindian projectile systems, which seems promising but needs better experimental support. 2. Using velocity and mass we can calculate kinetic energy and momentum of various projectiles as measures of weapon effect, and consider, for an example, Southwestern atlatls and bows.
