Lake Urmi is identified as the lake of Zarathustra’s home and as part of the starting point for his journey into the mountains. Though the text gives no further description of the lake, its place in the opening establishes the home he leaves behind before beginning ten years of solitude and, eventually, his descent among humanity.

Identity and Setting

The opening account places Lake Urmi alongside Zarathustra’s home: at thirty, he leaves both and goes into the mountains. The later prologue passage describes it as the lake of his home, confirming its association with his point of departure without supplying further geographical or physical detail.

Role in Zarathustra’s Departure

The lake belongs to the threshold between Zarathustra’s former home and the mountain solitude he chooses. He remains in the mountains for ten years, enjoying his spirit and solitude, before his heart turns and he rises at dawn to address the sun. The narrative thus makes Lake Urmi part of the setting for a decisive movement away from home, while the mountains become the place from which his later journey down among people begins.

Narrative Significance

Lake Urmi appears only briefly, but its placement gives the prologue a clear point of origin. Zarathustra’s departure is not presented as an abstract change of mood: he leaves a named lake associated with home, enters the mountains, and later resolves to descend and distribute the wisdom he has gathered. The lake marks the first leg of that movement from home, through solitude, toward human company.
