Did you ever stand in a Cavern's Mouth

Did you ever stand in a Cavern's Mouth—
Widths out of the Sun—
And look—and shudder, and block your breath—
And deem to be alone

In such a place, what horror,
How Goblin it would be—
And fly, as 'twere pursuing you?
Then Loneliness—looks so—

Did you ever look in a Cannon's face—
Between whose Yellow eye—
And yours—the Judgment intervened—
The Question of "To die"—

Extemporizing in your ear
As cool as Satyr's Drums—
If you remember, and were saved—
It's liker so—it seems—
