Toward the top of the Gorge, the river is known as the Dictynna. When it goes underground for a distance, it is known as the Aphaia, or "hidden one". Where it springs up again at Kefalovrysi ("Springhead") it then is knonw as the Britomartis. Dictynna was an ancient Minoan goddess and the Gorge was believed to belong to her. Britomartis was her daughter, first "hidden" in her mother's body, and then springing to life.
