Shakespeare's 115th sonnet, a sonnet which contains a hidden message that is revealed when the poem is formatted with the appropriate font and character spacing. In the spirit of this, the anagram also contains a similarly-placed message.
Those lines that I before have writ do lie, Even those that said I could not love you dearer, Yet then my judgment knew no reason why, My most full flame should afterwards burn clearer, But reckoning time, whose millioned accidents Creep in 'twixt vows, and change decrees of kings, Tan sacred beauty, blunt the sharp'st intents, Divert strong minds to the course of alt'ring things: Alas why fearing of time's tyranny, Might I not then say 'now I love you best,' When I was certain o'er incertainty, Crowning the present, doubting of the rest? Love is a babe, then might I not say so To give full growth to that which still doth grow. = With vows I've often sworn to bare untruth, In thoughtless wrongs and strained conviction born; Transcending now the ghost-like ties of youth, Time's limit leaves it vacant and forlorn. Though gayly I maintain'd that share of love, Bewitched by trenchant thought beyond belief, Came down relentlessly the guilt thereof To germinate despair and roots of grief. While yet in frantic worry now today We test our climate by 'Who loves me best?', Just as the aging love-force here can't stay When humble courtesy is not expressed. This strange and child-like act I now suspend Until my streaming tears might know their end.
