Product description
Vikings are said to have used a 'sunstone' for their navigation at sea: a piece of calcite that splits sunlight into two beams of light. By the stone By rotating until both beams have equal intensity, you can determine the position of the sun — even in cloudy, fog or twilight conditions.
This set contains the calcite sunstone in a fabric pouch with drawstring, plus a card with instructions for use. An attractive, functional object for Viking reenactment.
