But there are four differences of visible things, some cannot see but by day, the others, on the contrary, but by night, others by day and night, and others that have no place in darknesse. Colours are not seen but by day, not by night; Of things called resplendent, some by day, others by night, others by day and night; for there are some that are illustrious and cleare, others darke and heavy, and others betwixt both; others that have lustre and splendor, dark and waterish, and are not seene but by night, as the foresaid flyes, worms, fish scales, rotten wood, and the like, for in the day time their splendor is surmounted by another more powerfull which defaceth it; as also there are more stars, so that the darker the night is, the clearer they shine. Those betwixt both, as the Moon and some Stars, by day and by night, as the morning and the evening Stars, called by the Greeks _Phosphor_, by the Latines _Lucifer_, this is _Venus_ Starre. Fire also which pierceth the air more then it may, and illustrates it to demonstrate the colours that are therein; for the rest it is content to make it see, without bringing into action the transparence that is in the air, as we may see in the darke, where wee see fire a great way off, but not by the colours that are betwixt them. By day it shines also, but not act against the air, for that it is suffocated and extinguished by a stronger light. The clearnesse of the Moone likewise, for that shee is not very dark, shee is seen in the day time, but better in the night. _Suidas_ runs through all this; But to the purpose of lights without heat, I have read of nothing more admirable and strange, then that which _Gonzalo de Oviedo_ in the 15. Book 8. chap. of his _Naturall History of the Indies_, alledgeth of a certain little flying animal, of the bignesse of an Hanneton, very frequent in the Isle of _Spaine_, and in other Islands thereabouts, having two wings above, strong and hard, and two below them, two others more thinne and fine. The little beast called _Cocuye_, hath shining eyes as lighted candles, so that wheresoever he passes he illuminates the air, and gives it such a brightnesse that a man may see him a great way off, and in a chamber as dark as it may be, even at midnight, men may read and write by the light that comes from them; So that if a man binde two or three together, this would give more light then a Lanthorne or a Torch, in the field: and amidst the Woods in the night, as darke as may bee, they make themselves to be seen more then a mile. This clearnesse consists not onely in the eyes but also in their flanks, when they open their wings. They are accustomed to serve themselves with them, as we do with a Lamp or other light, to sup at night, and to do the affairs of the house. But when he comes to determine and dye, its light extinguisheth also. The Indians had a custome to make a post of them to strike feare in seeing them by night, for that it seemed that they had
