Behold the Sea, The opaline, the plentiful and strong, Yet beautiful as is the rose in June, Fresh as the trickling rainbow of July; Sea full of food, the nourisher of kinds, Purger of earth, and medicine of men; Creating a sweet climate by my breath, Washing out harms and griefs from memory, And, in my mathematic ebb and flow, Giving a hint of that which changes not.
