One of the earliest Mother's Day celebrations can be traced back to the celebration of Rhea, the Mother of Gods, by ancient Greeks.

• Herstory of Rhea
  In classical Greek mythology, Rhea was the Titaness daughter of Uranus (Father Sky/Father Heaven) and Gaia (Mother Earth) in classical Greek mythology.

  Rhea was married to his brother Titan, whom castrated Uranus to take over the throne as the King of Gods. Uranus predicted that Cronus was destined to be overcome by his own child as he had overthrown his own father. Cronus was adamant in not fulfilling this prophecy and resorted to swallowing his children (Hestia, Demeter, Hera, Hades, and Poseidon) as soon as Rhea had given birth to them.

• A Mother's Love
  When Rhea was pregnant with her sixth child (later named Zeus), Rhea was determined to save him from his husband's malevolence. With the help of Uranus and Gaia, Rhea devised a plan so that both Rhea and Uranus would get their retribution for Cronus' evil acts of overthrowing Uranus and killing her children.

  Rhea gave birth to Zeus in Crete, one of the thirteen peripheries of Greece, and handed Cronus a stone bundled in clothes which Cronus quickly swallowed. Rhea then hid Zeus in a cave on Mount Ida in Crete where it was believed Gaia raised him. Some believed that Zeus was suckled by a goat while a company of Kouretes, soldiers, and smaller gods made noise so that Cronus would not hear the Zeus' cries. Others believed that Zues was raised by a nymph who fed him goat milk and dangled him on a rope from a tree so he was suspended between earth, sea, and sky and thus, invisible to his father.

• A Child's Gratitude
  When Zeus was much bigger, he forced Cronus to disgorge the children he had swallowed – Cronus' brothers (the Gigantes, the Hecatonchires and the Cyclopes ) and Zeus siblings. Then, Zeus and his siblings, together with the Gigantes, Hecatonchires, and Cyclopes, overthrew Cronus and the other Titans.

• Celebrating the Mother of Gods
  The ancient Greeks partook in spring rites to honour Rhea. These celebrations were probably where modern-day Mother's Day celebrations were derived from. Today, Rhea is remembered in astrology as the name of the second largest of Saturn's (Zeuss) 14 satellites (moons).
