122 MOTION OF THE COMET OF 1577. 



LIB. in. they should be fixt, without mooving circularly, if the sphere 

 where they are did not moove ; if it be not as we faine, that 

 some Angell or intellectuall Spirite dooth walke with the 

 Cornet, guiding it circularly. In the yeere of our Lord God 

 one thousand five hundred seaventy and seaven appeered 

 that wonderfull Comet (in forme like vnto a feather) from 

 the horizon almost to the middest of heaven, and continued 

 from the first of November vntil the eight of December. I 

 say from the first of November, for although in Spaine it 

 was noted but the ninth of November (according to the testi 

 mony of Writers of that time), yet at Peru, where I was then, 

 I remember well we did see it and observe it eight dayes 

 before, and all the time after. Touching the cause of this 

 i diversity (some may dilate vpon it particularly) I will onely 

 show that during those fourtie dayes which it continued we 

 all observed (both such as were in Spaine and we that lived 

 then at the Indies) that it mooved daily with an vniversall 

 motion, from East to Weast, as the Moone and other 

 Planets, wherby it appeeres that the sphere of the aire 

 being its Region, the element it selfe must of necessitie 

 moove after the same sort. We noted also, that besides 

 this vniversall motion it had an other particular, by which it 

 moved with the planets fro west to east, for every night it 

 turned more Eastward, like vnto the Moone, Sunne, and 

 Planet of Venus. Wee did also observe a third particular 

 motion, whereby it mooved from the zodiacke towards the 

 North ; for after some nights it was found nearer vnto the 

 Septentrionall signes. And it may be this was the reason 

 why the great Comet was sooner seene by those that were 

 southerly, as at Peru, and later discovered by them of 

 Europe ; for by this third motion (as I have saide) it 

 approached neerer the Northerne Regions. Yet every one 

 may well observe the differences of this motion, so, as wee 

 may well perceive, that many and sundry celestiall bodies 

 give their impressions to the sphere of the aire. In like
