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.

PROBLEME III.

To find the Place of the Sun in the Ecliptick, the Day of the Moneth being first known.

SEek the Day of the Moneth in the Circle of Moneths upon the Horizon, and right against it in the Circle of Signes is the degree of the Ecliptick the Sun is in.

Example.

Imagine the Day to be given is May 10. therefore I seek on the Horizon in the Circle of Moneths, for May, and find the Moneths divided into so many parts as there is Daies in the Mo∣neth; which parts are marked with Arithmetical figures, from the beginning of the Moneth to the end, and denote the number of the Day of the Moneth that each Division represents: there∣fore among the Divisions I seek for 10, and directly against it in the Circle of Signes, I find ♉ 29. degrees. Therefore I say May 10. the Suns Place is in 29. degrees of ♉.

But note, that if it be Leap Year, instead of the 10. of May you must take the 11. of May: because February having in a Leap Year 29. Daies, the 29. of February must be reckoned for the first of March, and the first of March for the second of March; the second of March for the third of March; and so throughout the year.

The Leap Year is caused by the six od hours more then 365. daies that are assigned to every common Year: so that in a Re∣volution of 4. Years, one Day is gained, which is added to Fe∣bruary; and therefore February hath every fourth or Leap Year 29. Daies.
