Arbitrantur alii tunc iridis formam rebus apparere mundanis, cum altius delatae nubi crassae radii solis infusi, lucem iniecerint liquidam, quae non reperiens exitum, in se conglobata nimio splendescit attritu, et proximos quidem albo colores a sole sublimiore decerpit, subvirides vero a nubis similitudine superiectae, ut in mari solet usu venire, ubi candidae sunt undae quae litoribus illiduntur, interiores sine ulla concretione caerulae.
Others think that the form of the rainbow appears to earthly sight when the rays of the sun penetrate a thick and lofty cloud and fill it with clear light. Since this does not find an outlet, it forms itself into a mass and glows from the intense friction; and it takes the colours nearest to white from the sun higher up, but the greenish shades from resemblance to the cloud just above it. The same thing usually happens with the sea, where the waters that dash upon the shore are white, and those further out without any admixture are blue.
