Mercury, or quicksilver, was one of the seven alchemical metals.  It was believed to transcend the liquid/solid boundary.  It was also known as " Azoth", a word possibly created from the first letter (A) and last letters of the Latin, Greek and Hebrew alphabets (Z/O/Th), representing the beginning and end of all creation.
