A silver Peruvian atlatl from the 12th-15th century Atlatl in use. A spear-thrower, spear-throwing lever, or atlatl (pronounced / ˈ æ t l æ t əl / ⓘ [1] or / ˈ ɑː t l ɑː t əl /; [2] Nahuatl ahtlatl [ˈaʔt͡ɬat͡ɬ]) is a tool that uses leverage to achieve greater velocity in dart or javelin-throwing, and includes a bearing surface that allows the user to store energy during the ...
Spear-thrower or atlatl, a tool that uses leverage to achieve greater velocity in dart-throwing, and includes a bearing surface which allows the user to store energy during the throw; Woomera (spear-thrower), a wooden Australian Aboriginal spear-throwing device similar to an atlatl
A Swiss arrow [1] (also known as a Yorkshire arrow, Dutch arrow, Scotch arrow, or Gypsy arrow) is a type of enlarged dart in the shape of an arrow that is thrown with the aid of a lanyard, which is retained by a small notch close to the fletching. It is very similar to an amentum and uses the same throwing principle as a spear-thrower.
A woomera is an Australian Aboriginal wooden spear-throwing device. [1] [2] [3] Similar to an atlatl, it serves as an extension of the human arm, enabling a spear to travel at a greater speed and force than possible with only the arm.
Depending on your height, you'll want to use a dart that's about a foot taller than you are for better accuracy. Using an atlatl can be easy. Hitting a target is another story.
Stability in flight was important because it allowed the javelin to land on its point, which was the only way the throw could be accurately recorded in competition or be useful against a live target. An amentum also increased the effective length of the throwing arm, as does a spear-thrower, so enhanced speed. It is very similar to the Swiss arrow.
'arrow, dart', and μαντεία, manteia, 'divination'. Belomancy was anciently practiced at least by Babylonians, Greeks, Arabs and Scythians. The arrows were typically marked with occult symbols and had to have feathers for every method. In one method, different possible answers to a given question were written and tied to each arrow.
Posner devised a scheme of using valid and invalid cues across trials. In valid trials, the stimulus is presented in the area as indicated by the cue. For example, if the cue was an arrow pointing to the right, the subsequent stimulus indeed did appear in the box on the right.
