Anemoscope
An anemoscope is a device designed to show the direction of the wind, or to indicate a change of wind direction. The name is usually applied to an apparatus consisting of a wind vane above, connecting to a building below by some kind of coupling, and with a dial or index with pointers to show the direction and changes of the wind.
Anemoscopes existed in antiquity and have evolved into modern mechanical and electronic instruments. The word is first recorded in English in the period 1700–10. It derives from the Greek word for wind + -scope.
Should not be confused with the anemometer, a device to measure the speed of the wind, alongside which it is often deployed.
In antiquity the direction of the wind was indicated by the direction of smoke or the lifting of a flag. The anemoscope then formed a base by which the formal direction of the wind could be gauged.
The wind indicator (anemoscope) of Timosthenes (fl. 270 BCE) consisted of a disc with radius which indicated the direction of the system of twelve winds devised by him . (Aparctias, Boreas, Kaikias, Apeliotes, Euros, Euronotos, Notos, Libonotos, Lips, Zephyros, Argestes, Thrascias).
Tower of the Winds, is 2nd century BC structure in Athens. A bronze Triton once served as a weather-vane but has been lost. Eight sculptures remain around the base. These bass relief flying figures representing the winds, and under each was once a sun-dial.There was also a water-clock. As the tower was forty feet in height and twenty-seven in diameter, it still forms a striking object. This Tower of the Winds is the oldest known construction for observing the winds,
An ancient anemoscope described by Vitruvius (1st century BCE), seems to have been intended to show which way the wind actually blew, rather than to foretell into which quarter it would change. The later anemoscope of Eftropiou is of similar design.
Hygroscopic devices, in particular those utilizing catgut, were considered as very good anemoscopes, seldom failing to foretell the shifting of the wind.[citation needed]
