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.

PROBL. XI.

The Hour of the Day given, to find the Heigth of the Sun.

THe Globe &c. Rectified. Turn about the Globe till the Index of the Hour-Circle point (in the Hour-Cir∣cle) to the Hour of the Day: Then bring the Qua∣drant of Altitude to the Suns Place in the Ecliptick, and the degree on the Quadrant which touches the Suns Place, shall be the number of degrees of the Suns Altitude.

Example.

May 10. here at London; At 53. Minutes past 8. a clock in the Morning, I would know the Heigth of the Sun above the Ho∣rizon. Therefore I turn about the Globe till the Index of the

Hour-Circle come to 53: Minutes past 8. a clock (which is almost 9.) in the Hour-Circle: And keeping the Globe to this Posi∣tion, I bring the Quadrant of Altitude to the Suns place, viz. 〈◊〉〈◊〉 29. (found by the third Probleme) and because the Suns Place touches upon 40. degrees of the Quadrant, therefore I say May 10. 53. Minutes past 8. a clock in the Morning, here at London, The Sun is just 40. degrees above the Horizon; or which is all one, hath 40. degrees of Altitude.
