OF TYCHO BRAHE

A CALCULATION PLACING THE COURSES AND ALTITUDES OF THE PLANETS BEFORE THE EYES.

A detailed hand-colored engraved celestial diagram illustrating the Tychonic system. The Earth is positioned at the center, with the Sun orbiting it. The other planets (Mercury, Venus, Mars, Jupiter, and Saturn) orbit the Sun. Large concentric rings represent the spaces between planetary spheres, labeled with distances and relative altitudes. The outermost ring depicts the Zodiac with symbols and figures for the twelve constellations. The corners feature decorative cartouches and figures: an astronomer with a quadrant, another with a celestial globe, and two putti in the bottom corners with astronomical instruments. The central part of the diagram contains a vertical axis labeled "Diameter of the Firmament."

THE ZODIAC OR DODECAMORION division into twelve parts OR THE GREATEST CIRCLE OF THE EIGHTH SPHERE COMPREHENDING THE TWELVE CELESTIAL SIGNS, CONCENTRIC TO THE EARTH, ECCENTRIC TO THE SUN.

BETWEEN THE SPHERE OF THE FIXED STARS AND THE ORBIT OF SATURN

SATURN'S GREATEST BOREAL northern ALTITUDE, OR ELONGATION, AND DISTANCE FROM THE TERRESTRIAL GLOBE, WHEN IT IS IN APOGEE.

Saturn's least boreal altitude, or elongation, the distance from the Terrestrial Globe when it is in perigee

The distance and mean, or moderate, elongation of Saturn

BETWEEN THE SPHERE OF SATURN AND JUPITER

JUPITER'S GREATEST ALTITUDE, OR BOREAL APOGEAN ELONGATION
