according to ancient greek myth who is the chief god
Zeus Zeus (/zjuːs/;[3] Greek: Ζεύς Zeús [zdeǔ̯s])[4] is the sky and thunder god in ancient Greek religion, who ruled as king of the gods of Mount Olympus. His name is cognate with the first element of his Roman equivalent Jupiter. His mythologies and powers are similar, though not identical, to those of Indo-European deities such as Indra, Jupiter, Perun, Thor, and Odin.[5][6][7]
Titan (mythology) In Greek mythology, the Titans (Greek: Τιτάν, Titán, plural: Τiτᾶνες, Titânes) and Titanesses (or Titanides; Greek: Τιτανίς, Titanís, plural: Τιτανίδες, Titanídes) were members of the second generation of divine beings, descending from the primordial deities and preceding the Olympians. Based on Mount Othrys, the Titans most famously included the first twelve children of Gaia (Mother Earth) and Uranus (Father Sky). They ruled during the legendary Golden Age, and also comprised the first pantheon of Greek deities.
