A still—Volcano—Life—
That flickered in the night—
When it was dark enough to do
Without erasing sight—
A quiet—Earthquake Style—
Too subtle to suspect
By natures this side Naples—
The North cannot detect
The pattern of  oxymora  is continued here, this time with “quiet” and “Earthquake.” It should be noted that, in the oxymora of the first line of each stanza (“A still – Volcano – Life” / “A quiet – Earthquake Style” / “The Solemn – Torrid – Symbol –”), the opposites are used to define “Life,” “style,” and “Symbol.” In the second stanza, the idea of “style” could refer to both Dickinson’s poetic style (brief yet powerful) or, more personally, her own self (quiet yet quaking with perceptiveness).
