*Mythological Reference:
Cronus, youngest of the Greek Titans, was the son of Uranus and Gaia. After Cronus assumed the throne, he learned that he was fated to be overthrown by one of his own children. To prevent this, he would swallow his children whole after their birth. Rhea, Cronus's wife, hid her son Zeus. After Zeus had grown into a young man, he led a revolt against his father, defeated him and banished him along with all the Titans.
Teal'c's father was once first prime of Cronus, but was executed for failing a mission. Because of this, Teal'c chose to become first prime of Apophis and vowed vengence on Cronus. Cronus owes his life to Major Carter, who saved him using a Goa'uld healing device after Nirrti tried to kill him.
