The association with the Leviathan makes it a symbol of depth and surfacing. The multiple crossroads of two crosses can be interpreted as a sign of free choice, it can also be seen as a stroke-through "equal-to" (=) to show that every person has their own life.
Sulfur (“Leviathan Cross”) A symbol for the alchemical element Sulfur, (Brimstone) which is spiritually analogous to the human soul. Alchemically, sulfur has the qualities of masculine, hot and dry. Combined with Mercury (feminine, cool and moist), the pair were considered the parents of all metals.
Alchemical drawings often portray Sulfur as the sun. (In some views, sulfur and salt are the parents of Mercury) The symbol of sulfur is often used as an identifying symbol by Satanists, due to sulfur’s historical asociation with the devil.
