M. Blundevile his exercises containing sixe treatises, the titles wherof are set down in the next printed page: which treatises are verie necessarie to be read and learned of all yoong gentlemen that haue not bene exercised in such disciplines, and yet are desirous to haue knowledge as well in cosmographie, astronomie, and geographie, as also in the arte of navigation ... To the furtherance of which arte of navigation, the said M. Blundevile speciallie wrote the said treatises and of meere good will doth dedicate the same to all the young gentlemen of this realme.

The vse of the Table.

Now the vse of the saide Table is thus: whensoeuer you would knowe in what houre of the day or night any Planet raigneth, you must first séeke out the houre of the day or night, and if it be of the day, then you shall finde it in the first rowe of the front, if of the night, in the second rowe of the front, as hath béene saide before: and from that houre descende with your finger to the com∣mon Angle standing right against the day which you séeke, and that will shewe you what Planet then raigneth. As for example, if you would know on Wednesday at 8. of the clocke of the day what Planet raigneth, then hauing found the number of 8. in the front, written in Arithmeticall figure, come straight downe from thence with your finger to the common Angle standing right a∣gainst Wednesday, and you shall finde that Mercurie raigneth. And if you would knowe what Planet raigneth the same day at the eight houre of the night, then descende from the houre of the night downe to the common Angle, and you shall finde that the sunne raigneth, and so foorth of all the rest.

The rule contained in one verse, and the vse thereof.

The rule in verse is thus:

Sol, Ve, Mer, Luna, Saturnus, Iupiter, & Mars.

These vii. wordes (the coniunction & being left out) doe signi∣fie the seuen Planets: For Sol is the Sunne, Ve standeth for Venus, Mer for Mercurius, Luna is the Moone, and the other thrée Planets following, as Saturnus, Iupiter, and Mars, doe make vp the number of seuen, which must alwayes followe one another, in such order as they are here set downe in the foresaide verse, and to haue the true vse of this rule, you must first apply euery Planet to his owne proper day, as Sol to Sunday, Luna to Munday, Mars to Tuesday, Mercurius to Wednesday, Iupiter to Thursday, Venus to Friday, and Saturnus to Saturday: for euery one of these Planets gouerneth the first houre of his owne proper day, and the Planet placed next to him in the verse, gouer∣neth the second houre of the same day, and so forth orderly, as for example, if you would knowe what Planet shall raigne on Sun∣day at the third houre of the day, you must first say that Sol doth

raigne the first houre because that is his day, and Venus raigneth the second houre, and Mercurie the third houre according to your rule, & so by kéeping the order of the verse, you shall easily appoint to euery houre both of the day and of the night artificiall his owne gouernour: For though both day and night be deuided ech of them into 12. houres, making in all 24. houres, and that there be but seuen Planets, yet by appointing euery Planet to his owne proper day as gouernour of the first houre of the same day, and by obseruing the order of the verse in repeating the said Planets, you shall not faile to giue to euery houre his proper Planet. Thus hauing sufficiently spoken of the celestiall part, I will now pro∣céede to the Elementall part of the worlde, contained in the se∣cond Booke of this Treatise.
