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. VI.

To find in what Circle of Position any Star, or any degree of the Ecliptick is.

CIrcles of Position are numbred from the Horizon up∣wards, upon the Quadrant of Altitude placed at the East or West point of the Horizon, Therefore when you would find what Circle of Position any Star or degree of the E∣cliptick is in, Rectifie the Globe and Quadrant of Altitude, and bring the lower end of the Quadrant of Altitude to the East or West point of the Horizon, and lift up the Circle of Position till it come to the Star or degree of the Ecliptick proposed: and the number of degrees the Circle of Position then cuts in the Qua∣drant of Altitude is the number of the Circle of Position that the Star or degree of the Ecliptick is in. If the Star or degree of the Ecliptick be under the Horizon, turn the Globe about till 180, degrees of the Equator pass through the Meridian, then will the Star or degree of the Ecliptick be above the Horizon: Lift up then the Circle of Position (as before) to the Star or degree of the Ecliptick and the number of degrees of the Quadrant of Al∣titude the Circle of Position cuts on the East side, is the number of Circles of Position the Star was under the Horizon on the West side: Or so many degrees as the Circle of Position cuts on the Quadrant of Altitude in the West side the Horizon is the number of the Circles of Position the Star or degree of the Ecliptick was under the Horizon on the East side.
