The sacred Betis strewed the wavy shore

"The sacred Betis strewed the wavy shore With purple flowers, fine emeralds, golden ore, And tender pearls; toward heaven he raised his head, Adorned with grasses, reeds, and corals red; Spread o'er the sands the moving glass that shot Capricious lustres round his shadowy grot; Then stretched his humid horns, increasing so His affluent floods, dilated in their flow;— Swift roll his billows, murmuring, pure, and cool, And into ocean far extend his rule."
