Rhea was the Goddess of female fertility, motherhood, and generation
One of the most interesting facts about Rhea is she was the Goddess of female fertility, motherhood, and generation. Rhea, a titan goddess, demonstrated her procreative ability by giving birth to six of the most powerful gods and goddesses. She was revered by the Greeks as the goddess of maternity, birthing children, and providing for them.
Her body is connected to the flow of time, menstrual blood, birth waters, milk, and ease and flow, as her name implies. Menstrual blood and birth water flowed, symbolizing fertility.
And the passage of time or generation is referred to as the "flow of time." Rhea, Cronus's wife and mother of the Olympians lived through Titan and Olympian ages. She was hence referred to as the Greek Goddess of generation.
She was also revered as the Goddess of ease and comfort. "The gods who live at their Rhea (ease)," was the phrase used to sanctify her name.
