nocte volat caeli medio terraeque per umbram, stridens, nec dulci declinat lumina somno; luce sedet custos aut summi culmine tecti, turribus aut altis, et magnas territat urbes, tam ficti pravique tenax quam nuntia veri.
By night, midway between heaven and earth, she flies through the gloom, screeching, and droops not her eyes in sweet sleep; by day she sits on guard on high rooftop or lofty turrets, and affrights great cities, clinging to the false and wrong, yet heralding truth.
