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.

PROB. I.

The Suns Amplitude and Difference of Ascension gi∣ven, to find the Heigth of the Pole, and Declination of the Sun.

ELevate the Pole so many degrees as the Difference of the Suns Ascension is, and screw the Quadrant of Altitude to the Zenith, and bring the first point of ♈ to the Me∣ridian, then number on the Quadrant of Altitude up∣wards the complement to 90. of the Suns Amplitude, and move the Quadrant of Altitude till that number of degrees cuts the E∣quator; So shall the Quadrant cut in the Horizon the degree of the Pole Elevation; and in the Equator the degree of the Suns Declination.

Example.

The difference of Ascension is 27. degrees 7. minutes. There∣fore I Elevate the Pole 27. degrees 7. minutes above the Hori∣zon, and screw the Quadrant of Altitude to 27. degrees 7. mi∣nutes, which is in the Zenith: then I bring the first point of ♈ to the Meridian, and number on the Quadrant of Altitude up∣wards 56. degrees 40. minutes, the Complement of the Suns Amplitude, and bring that degree to the Equator; then I see in what degree of the Horizon the Quadrant cuts the Horizon, and find 51 ½, which is the Elevation of the Pole: then looking in what degree of the Equator the Quadrant of Altitude cuts the Equator, I find 20 degrees, 5 min. which is the Declination of the Sun at the same Time.
