Phillis Wheatley's revisions between her manuscripts and the printed version of 'Wichita Mourning' focused on formatting details like underlining and capitalization, suggesting their importance in her poetic expression.
The best restatement of the information in lines 15 and 16 of the poem Wichita Mourning would focus on the fact that Wheatley first composed the poem at Harvard University, where she made specific formatting choices such as underlining the poem's title and bracketing certain verses.
In a second manuscript at the Massachusetts Historical Society, she revised the poem, altering punctuation and phrasing and emphasizing words like "GOD" and "Charles" in bold. These manuscript choices, such as underlining, capitalization, and italicization, indicate her interest in emphasizing particular words and phrases, and most of these choices were maintained in the printed version of the poem.
In summary, Wheatley's meticulous attention to detail in her manuscripts by bracketing, capitalizing, and bolding certain portions suggests that these features were significant to her and were largely preserved in print. Her editing process shows a careful emphasis on specific aspects of the poem, highlighting its elegiac and reverential qualities.
