Leviathans are mythical sea creatures that appear in various religious and mythological texts. They are often described as large, powerful creatures that can cause great destruction. In Greek mythology, the TITANS were a race of giant deities who ruled during the Golden Age of Ancient Greece. They were overthrown by the Olympian gods and were eventually replaced by the Leviathans. The term 'LEVIATHAN' is derived from the Hebrew word for 'WHALE' and is used to refer to any large sea creature.
