Shakespeare and perfume
Then were not summer's distillation left, A liquid prisoner pent in walls of glass, Beauty's effect with beauty were bereft, Nor it nor no remembrance what it was. But flowers distilled, though they with winter meet, Leese but their show; their substance still lives sweet.
What it means: If we didn't have perfume distilled from summer flowers to keep in a jar, the effects of summer would vanish at the end of the season. Without perfume, we'd have no way of remembering the summer itself or its beauty. But the flowers used to make perfume lose only their outward beauty when winter comes; their beautiful scent lives on sweetly.
Shakespeare Sonnet 5
