Shadows (Howe)/The Horizon at Sea

THE HORIZON AT SEA
A LINE inexorably straight,
In larger truth, a girdling ring,
Fixed either way as firm as fate,
And always onward beckoning.

Clear-cut and far, or near and blurred,
As powers of sun and cloud decree,
By these thy provocations stirred,
We seek the farthest mystery.

Emblem of boundaries strictly set,
Emblem of venturous search and hope,
Circled by thee can man forget
His limitation and his scope?
