Sources tell us that in the 4th century AD the principle of measuring density by immersing an object in fluid was already in use. The Arabic scientist Alhazen in the 11th century describes such an instrument, and states a table of densities. The instrument was a spindle engraved with a scale from which the density and thus the concentration could be read. Today this is known as an areometer.
