A tutor to astronomie and geographie, or, An easie and speedy way to know the use of both the globes, coelestial and terrestrial in six books : the first teaching the rudiments of astronomy and geography, the 2. shewing by the globes the solution of astronomical & geographical probl., the 3. shewing by the globes the solution of problems in navigation, the 4. shewing by the globes the solution of astrological problemes, the 5. shewing by the globes the solution of gnomonical problemes, the 6. shewing by the globes the solution of of [sic] spherical triangles : more fully and amply then hath ever been set forth either by Gemma Frisius, Metius, Hues, Wright, Blaew, or any others that have taught the use of the globes : and that so plainly and methodically that the meanest capacity may at first reading apprehend it, and with a little practise grow expert in these divine sciences / by Joseph Moxon ; whereunto is added Antient poetical stories of the stars, shewing reasons why the several shapes and forms are pictured on the coelestial globe, collected from Dr. Hood ; as also a Discourse of the antiquity, progress and augmentation of astronomie.

Example.

Spica Virgo is observed to have 28. degrees 57. min Meri∣dian Altitude; therefore I bring Spica Virgo to the Meridian, and raise it or depress it higher or lower as I find occasion, till it is just 28. degrees 57. min. above the Horizon: Then I count the number of degrees between the Pole and the Horizon, and find them 51½. Therefore I say the Elevation of the Pole is here at London 51½. Yet note, If the Star whose Altitude you observe have fewer number of degrees of Declination from the Pole, then the Elevation of the Pole, you may be apt to mistake in its coming to the Meridian; for those Stars never set; and there∣fore are twice Visible in the Meridian in 24. hours, once above the Pole, and once under the Pole.

If your Star have greater Altitude then the North Star, it is above the Pole; but if it have less, it is below the Pole: so that if you know but whether it be above or below, it is enough; for so you may accordingly raise it to the Altitude on the Me∣ridian it hath in Heaven, and joyn it to the Meridian either above or beneath the Pole, as the Star is placed in Heaven: and then the arch of the Meridian comprehended between the Pole and the Horizon, is the Elevation of the Pole, as aforesaid.
