Then Zephyr, the West Wind, blew away the clouds so that Apollo, the sun god, could shine and make the flower bloom. And so the rose was born and was immediately crowned Queen of the Flowers" (Pickles, 88). The first red roses were supposed to have sprung from the blood of Adonis, Aphrodite's lover.
