Saturnís ring

Saturnís ring

Fig. 1.18 . In 1659 Christiaan Huygens (1629-1695) published this drawing of Saturn and its ring in his monograph Systemia Saturnium. Huygens recognized that a detached ring would explain the planetís ever-changing appearance, and announced his discovery in the form of an anagram, a succession of scrambled letters. The drawing shown here was accompanied by the deciphered anagram ďSaturn is girdled by a thin flat ring, nowhere touching it, and inclined to the ecliptic."
