Analysis of You know that Portrait in the Moon

You know that Portrait in the Moon—
So tell me who 'tis like—
The very Brow—the stooping eyes—
A fog for—Say—Whose Sake?

The very Pattern of the Cheek—
It varies—in the Chin—
But—Ishmael—since we met—'tis long—
And fashions—intervene—

When Moon's at full—'Tis Thou—I say—
My lips just hold the name—
When crescent—Thou art worn—I note—
But—there—the Golden Same—

And when—Some Night—Bold—slashing Clouds
Cut Thee away from Me—
That's easier—than the other film
That glazes Holiday—
