Cronos - Saturn
In Greek mythology, Cronus, Cronos, or Kronos was the leader and youngest of the first generation of Titans, the divine descendants of Uranus, the sky, and Gaia, the earth. He overthrew his father and ruled during the mythological Golden Age, until he was overthrown by his own son Zeus and imprisoned in Tartarus. According to Plato, however, the deities Phorcys, Cronus, and Rhea were the eldest children of Oceanus and Tethys.
Cronus was usually depicted with a harpe, scythe or a sickle, which was the instrument he used to castrate and depose Uranus, his father. In Athens, on the twelfth day of the Attic month of Hekatombaion, a festival called Kronia was held in honour of Cronus to celebrate the harvest, suggesting that, as a result of his association with the virtuous Golden Age, Cronus continued to preside as a patron of the harvest. Cronus was also identified in classical antiquity with the Roman deity Saturn.

In fear of a prophecy that he would in turn be overthrown by his own son, Kronos swallowed each of his children as they were born. Rhea managed to save the youngest, Zeus, by hiding him away on the island of Krete (Crete), and fed Kronos a stone wrapped in swaddling clothes. The god grew up, forced Kronos to disgorge his swallowed offspring, and led the Olympians in a ten year war against the Titanes (Titans), driving them in defeat into the pit of Tartaros (Tartarus).
During antiquity, Cronus was occasionally interpreted as Chronos, the personification of time. The Roman philosopher Cicero (1st century BCE) elaborated on this by saying that the Greek name Cronus is synonymous to chronos (time) since he maintains the course and cycles of seasons and the periods of time, whereas the Latin name Saturn denotes that he is saturated with years since he was devouring his sons, which implies that time devours the ages and gorges.
During the Renaissance, the identification of Cronus and Chronos gave rise to "Father Time" wielding the harvesting scythe.
