Who ambushes whom in Dickinson

Who ambushes whom in the "fond Ambush" in Emily Dickinson's "I know that he exists" (365) can be addressed in ever wider contexts: one can look in the poem (for phrases, lines, or images that point in either direction) or in the poet's work as a whole, as in "He lived the Life of Ambush" (1571) or the veil in "My life closed twice before it's close" (1773); one can research such figures in Dickinson's poetic and theological contemporaries or beyond them to the literary and religious history of tropes of ambush and revelation. If this leaves the issue unresolved, the process still enriches understanding of the poem and the poet. (Andrew Shields, #111words, 17 April)
