According to legend, King Hera II of Syria suspected that the gold crown he ordered might have been mixed with other cheap metals, so he asked Archimedes to verify its composition without damaging the crown. Archimedes determined the density of the golden crown by measuring its mass in air and water, using the principle of buoyancy, and found that it was not pure gold.
