Sonnet Cxcvi:

My stain of earth hath mingled with the stream Of love that kisses thus thy ivory feet-- Perennial fountain, ever bland and sweet. Unvexed, and clearer than yon heavenly beam. Rages of passion, haply, sometimes seem To tear the dwelling where my heart doth beat; Or oftener still, its strait and dark retreat Groans with the nightmare of some hideous dream. Yet o'er this wrath, and this complaining moan, For many a day, my wizard love has stood, Ruling the issues of the heady flood; So that before thee it hath ever flown A crystal tide, with music in its tone, Albeit, within, distilled from very blood.
