Slate spindles are known to have been in use in Europe ever since the Stone Age, but in Finland they were especially common during the Iron Age and the Finnish Middle Ages, i.e. 500 BCE–1200 CE and 1200–1500 CE respectively. A spindle was an essential tool in a household and it was used for spinning yarn before the invention of the spinning wheel. A swastika has been carved on one side of this simple model for good luck. This spindle was found in the archaeological excavation of Aboa Vetus taking place this summer.
