and _Sterres_, to be to vs, for _Signes_, and knowledge of Seasons, and for Distinctions of Dayes, and yeares. Many wordes nede not. But I wish, euery man should way this word, _Signes_. And besides that, conferre it also with the tenth Chapter of _Hieremie_. And though Some thinke, that there, they haue found a rod: Yet Modest Reason, will be indifferent Iudge, who ought to be beaten therwith, in respect of our purpose. Leauing that: I pray you vnderstand this: that without great diligence of Obseruation, examination and Calculation, their periods and courses (wherby _Distinction_ of Seasons, yeares, and New Mones might precisely be knowne) could not exactely be certified. Which thing to performe, is that _Art_, which we here haue Defined to be _Astronomie_. Wherby, we may haue the distinct Course of Times, dayes, yeares, and Ages: aswell for Consideratiõ of Sacred Prophesies, accomplished in due time, foretold: as for high Mysticall Solemnities holding: And for all other humaine affaires, Conditions, and couenantes, vpon certaine time, betwene man and man: with many other great vses: Wherin, (verely), would be great incertainty, Confusion, vntruth, and brutish Barbarousnes: without the wonderfull diligence and skill of this Arte: continually learning, and determining Times, and periodes of Time, by the Record of the heauenly booke, wherin all times are written: and to be read with an _Astronomicall staffe_, in stede of a festue. +‡Musike‡+, of Motion, hath his Originall cause: Therfore, after the motions most swift, and most Slow, which are in the Firmament, of Nature performed: and vnder the _Astronomers Consideration_: now I will Speake of an other kinde of _Motion_, producing sound, audible, and of Man numerable. _Musike_ I call here that _Science_, which of the Grekes is called _Harmonice_. Not medling with the Controuersie betwene the auncient _Harmonistes_, and _Canonistes_. +Musike is a Mathematicall Science, which teacheth, by sense and reason, perfectly to iudge, and order the diuersities of soundes, hye and low.+ _Astronomie_ and _Musike_ are Sisters, saith _Plato_. As, for _Astronomie_, the eyes: So, for _Harmonious Motion_, the eares were made. But as _Astronomie_ hath a more diuine Contemplation, and cõmodity, then mortall eye can perceiue: So, is _Musike_ to be considered, [1.] that the * Minde may be preferred, before the eare. And from audible sound, we ought to ascende, to the examination: which numbers are _Harmonious_, and which not. And why, either, the one are: or the other are not. I could at large, [2.] in the heauenly * motions and distances, describe a meruailous Harmonie, of _Pythagoras_ Harpe [3.] with eight stringes. Also, somwhat might be sayd of _Mercurius_ * two Harpes, [4.] eche of foure Stringes Elementall. And very straunge matter, might be alledged of the _Harmonie_, [5.]
