Et quoniam indicium est permutationis aurae (ut diximus), a sudo aere nubium concitans globos, aut contra ex concreto mutans in serenam laetitiam caelum, ideo apud poetas legimus saepe, Irim de caelo tunc mitti, cum praesentium rerum verti necesse sit status.
And since the rainbow is an indication of a change of weather (as I have said), from sunny skies bringing up masses of clouds, or on the contrary changing an overcast sky to one that is calm and pleasant, we often read in the poets that Iris is sent from heaven when it is necessary to change the present condition of affairs.
