What was the thing that Mick was swinging around that made all that noise on the top of the mountain? And what was the point? To scare the bad guys I thought but I wasnt sure. Thanx for the help!!!
shareThe telephone, how communications were done by the locals

I figure that Wiki can describe it better:
The bullroarer, rhombus or turndun is an ancient ritual musical instrument and a device historically used for communicating over greatly extended distances. It dates to the Paleolithic period, being found in Ukraine dating from 17,000 BC. Anthropologist Michael Boyd, a Bullroarer expert, documents a number found in Europe, Asia, the Indian sub-continent, Africa, the Americas, and Australia.
In ancient Greece it was a sacred instrument used in the Dionysian Mysteries and is still used in rituals worldwide.
Along with the didgeridoo, it was a prominent musical technology among the Australian Aborigines, used in ceremonies across the continent.
A bullroarer consists of a weighted aerofoil (a rectangular thin slat of wood about 15 cm (6 in) to 60 cm (24 in) long and about 1.25 cm (0.5 in) to 5 cm (2 in) wide) attached to a long cord. Typically, the wood slat is trimmed down to a sharp edge around the edges, and serrations along the length of the wooden slat may or may not be used, depending on the cultural traditions of the region in question.
The cord is given a slight initial twist, and the roarer is then swung in a large circle in a horizontal plane, or in a smaller circle in a vertical plane. The aerodynamics of the roarer will keep it spinning about its axis even after the initial twist has unwound. The cord winds fully first in one direction and then the other, alternating.
It makes a characteristic roaring vibrato sound with notable sound modulations occurring from the rotation of the roarer along its longitudinal axis, and the choice of whether a shorter or longer length of cord is used to spin the bullroarer. By modifying the expansiveness of its circuit and the speed given it, and by changing the plane in which the bullroarer is whirled from horizontal to vertical or vice versa, the modulation of the sound produced can be controlled, making the coding of information possible. The low-frequency component of the sound travels extremely long distances, clearly audible over many miles on a quiet night.
