In Classical Greek mythology, the Titans (Greek: Τῑτάν Tītán; plural: Τῑτᾶνες Tītânes) and Titanesses (or Titanides) (Greek: Τῑτᾱνίς Tītānís; plural: Τῑτᾱνίδες Tītānídes) were members of the second order of divine beings, descending from the primordial deities and preceding the Olympian deities. Based on Mount Othrys, the Titans most famously included the first twelve children of the primordial Gaia (Mother Earth) and Uranus (Father Sky). They were giant deities of incredible strength, who ruled during the legendary Golden Age, and also composed the first pantheon of Greek deities.
