preserved by republication in Oribasius' fourth century Medical Collections. The figure is described as a sling to set and bind a broken jaw, with the chin being placed in the center of the figure and the four loops tied near the top of the head. Called the "Plinthios Brokhos", the resulting figure has been identified by multiple sources as the figure known to Aboriginal Australians as "The Sun Clouded Over". The Inuit are purported to possess a string figure representing the extinct woolly mammoth. String figures were widely studied by anthropologists like James Hornell from the 1880s through around 1900, as they were used in attempts to trace the origin and developments of cultures. String figures, once thought to have proven monogenesis, appear to have arisen independently as an entertainment pastime in many societies. Many figures were collected and described from south-east Asia, Japan, South America, West Indies, Pacific Islanders, Inuit and other Native Americans. Figures have also been collected in Europe and Africa. One of the major works on the subject is String Figures and How to Make Them (), by Caroline Furness Jayne. The International String Figure Association (ISFA) was formed in 1978 with the primary goal of gathering, preserving, and distributing string figure knowledge so that future generations will continue to enjoy this ancient pastime. Terms While in string figure literature there are many phrases often used, there may be some variation with the fingers, loops, and strings indicated in different ways. A loop is the strings that go around the back of a finger, multiple fingers, or another body part such as the wrist. Some authors name the strings, fingers and their loops (near middle finger string, right index finger, pinky loop, for example), while others number them (3n, R1, 5 loop). One of the first methods of recording figures and sets of terminology was an anatomical system proposed in "A Method of Recording String Figures and Tricks" by W. H. R. Rivers and A. C. Haddon. Though location or locations of a string are most often indicated by casual systems of terms such as "near" or "far", the Rivers and Haddon system is far less ambiguous, though this may be unnecessary for the most common, illustrated, figures. Below are some common moves, openings, and extensions. Openings Murray Opening/Index Opening: The loop is grasped with the middle, ring, and little fingers so that there is a
