I don't know how to translate the title of the above painting by Julio Romero de Torres -- every possible rendition of
¡Viva el Pelo! into English sounds silly -- but el pelo means the hair, so you get the idea.  The image reminds me of a line by the poet Robert Duncan, "in the dark of the moon the hair rules".  This in turn reminds me of something the poet Robert Browning said about his wife Elizabeth Barrett Browning after her death, when he was asked what it was like being married to such a famous person (she was far more famous than he was during her lifetime.)  Yes, she was known to the world, Browning admitted, "but I knew her on the dark side of the moon" -- the side of the moon the world never sees . . . where the hair rules.
