To him was attributed the rain; for he made it, he caused it to come down, he scattered the rain like seed, and also the hail. He cause to sprout, to blossom, to leaf out, to bloom, to ripen, the trees, the plants, our food. And also by him were made floods of water and thunder-bolts. And he was thus decorated: his face was thickly painted black, his face was painted with liquid rubber; it was anointed with black; his face was {spotted} with {a paste of} amaranth seeds. He had a sleeveless cloud-jacket of netted fabric; he had a crown of heron feathers; he had a necklace of green stone jewels. He had foam sandals, and also rattles. He had a plaited-reed banner.
