I am a belt that holds a vast, blue gown. You cannot buckle me up or down. Ships cross my line, but I am never wet.

I appear as triangle, but I am not geometric. People associate me with river.

Each day, I rise, I recede, never fall: lands of earth know my touch, one and all- The wise once saw me as proof, the world is round: for heavens move me, a truth profound.

I stand tall and wrapped in stripes The fat of giant sea beasts fuels my light My glowing eye burns through the grey A mighty guide till the break of day

I can never be found but all know my name. I appear on no map and stay where I stay.
