Cronus

Cronus (also spelled Cronos or Kronos) was a central figure in Greek mythology, known as the leader of the first-generation Titans. Born to the primordial deities Gaia (Earth) and Uranus (Sky), he was their youngest child. Though Plato presents an alternative genealogy, describing Cronus as one of the eldest offspring of Oceanus and Tethys, along with his siblings Phorcys and Rhea.
Cronus rose to power by overthrowing his father Uranus, using a harpe (a curved blade resembling a scythe or sickle) to castrate him. He then ruled during what mythology calls the Golden Age, until his own son Zeus eventually overthrew him and imprisoned him in Tartarus.
Despite his violent past, Cronus maintained a lasting connection to agriculture and harvest. In Athens, people celebrated a harvest festival called Kronia in his honor on the twelfth day of Hekatombaion (an Attic month). This association likely stemmed from his reign during the Golden Age, which was remembered as a time of virtue and abundance. The Romans later identified Cronus with their god Saturn, incorporating many of his attributes and myths into their own religious tradition.
