Classic Poem

Who thou art I know not,
But this much I know:
Thou hast set the Pleiades
In a silver row;

Thou hast sent the trackless winds
Loose upon their way;
Thou hast reared a colored wall
Twixt the night and day;

Thou hast made the flowers to blow,
And the stars to shine;
Hid rare gems of richest ore
In the tunneled mine —

But, chief of all thy wondrous works,
Supreme of all thy plan,
Thou hast put an upward reach
In the heart of Man.
